To qualify myself, I am 68, have the equivalent of two degrees in marine electronics from English
Royal Navy and 46 years hands on successful experience. I run my own marine electronics company,
eliminating electrolysis corrosion and providing testimonials with references and contact details.
There have been no claims since we began commercialization in 1993. See
www.seabis.com/testimonials.html
ABYC Wiring Rules, available here, mandate that neither battery terminal via any wiring or otherwise
must touch any metal that can get other than absolutely dry. The Bonding System must make no
electrical contact to either battery terminal. A breach of this internationally recognized Wiring Rule
will result in insurance against corrosion being void. The correct procedure is to prove electrical
insulation (isolation) at all battery wiring under full power and fully operational conditions, from all
metal that may be even remotely other than absolutely dry. That is the result of the SeaBis System.
Metal corrosion explanation:
Metal corrosion is caused by electrolytic action, termed electrolysis, between damp or wet metal or
heating / cooling systems via any other than absolutely dry contact to the Earth. Electrolysis is
particles of metal being dissolved from your metal by battery current. Battery current is DC - Direct
Current so always flows in the same direction carrying particles of your metal with it. AC (Mains
power) is Alternating Current that reverses direction every half cycle (Hertz or 1/60 or 1/50 second)
so dissolved particles will be replaced every half cycle. So AC cannot cause electrolysis corrosion.
All electronics must use DC. All electrolysis is eliminated by the SeaBis System under actual live use
conditions.
In doubt? Ask any manufacturing jeweler how he plates gold onto base metal. The gold is your
(metal / engine / hull) damp or wet metal and the (jewelry) base metal is the Earth.

How to Eliminate Electrolysis Corrosion:
Metal corrosion has three causes:
Rust
Is of very low ferocity compared to electrolysis corrosion. It can only be present when there
is any moisture in the air. Rust is easily prevented by paint or plating after electrolysis is
eliminated by the SeaBis System.
Galvanic
Compared to electrolysis corrosion galvanic corrosion is also of very low ferocity. Galvanic
corrosion is easily eliminated by anodes but only after electrolysis is eliminated by the SeaBis
System. Sacrificial Anodes can then work as designed. Galvanic corrosion is caused by the
natural voltage between two different metals in a conductor such as fresh or salt moisture or
water. This voltage never exceeds 1 point 2 volts and current is in the millionths of an amp
Galvanic corrosion is at a very very low level compared to the electrolysis corrosion we are
only too familiar with.
Electrolysis
Is 1,000 to 1,000,000 greater ferocity than rust or galvanic corrosion. It is generated by the
motor / plumbing / railway system / engine / propeller / metal hull / keel / any metal being at
a voltage different to the Earth or any other source. It flows as current from the installation
to the Earth, other vessels and installations. Electrolysis corrosion can only be measured as
current then eliminated by the SeaBis System. See an explanation at Seabis Explanation.
We guarantee the SeaBis System will eliminate all electrolysis corrosion - money back - for 3
years in writing here. Testimonials with verification contacts here.

How to Eliminate Electrolysis Corrosion:
SeaBis Explanation:
SeaBis indicates electrolysis capable current, and its severity. When Process of Elimination
instructions, supplied with the SeaBis System are completed, all metal / engine / propeller /
metal hull / keel will be disconnected (electrically Open Circuit) from the Earth / soil / air /
moisture / and water. Your metal is immune to electrolysis corrosion. It cannot create or be
influenced by electrolysis corrosion. Electrolysis corrosion is conquered.
Most electronics / electrics only fully power up when in full use, and full use is often when
the electrolysis occurs. It is therefore advisable to install and leave SeaBis turned on
permanently. When SeaBis detects electrolysis it will alarm and indicate the severity and
direction of the electrolysis. Fault finding is by unplugging / disconnection of equipment until
SeaBis indicates Normal then follow Process of Elimination instructions to complete the
repair.
Continuous flashing of “AC only alarm” indicates AC voltage component exceeding 2 volts.
Your battery life is at least halved. The AC isolating transformer may not be effective or you
may be using a electrically noisy inverter or there may be poor earth connection or reversed
Active, Neutral or Earth. Ask a Licensed Electrician to check no hull DC path to shore AC
mains power either via mains active, neutral or earth. SeaBis will detect and indicate this DC
path. Follow Process of Elimination instructions, supplied with SeaBis. As a last resort only,
use an isolating transformer to stop this path. An incorrectly connected Isolating Transformer
and associated vessel Earth connection introduces a lethal risk. It is far better to use Seabis to
eliminate the cause. Call us if in doubt. E-mail: [email protected]
How to Eliminate Corrosion:
Connect the SeaBis unit:
Connect the brown wire to battery positive and the blue wire to battery negative. Connect the
green/yellow wire to metal of the motor / engine, or metal housing / hull / plumbing / railway line.
Install anywhere dry. However never connect anything except batteries inside the battery box.
Batteries produce hydrogen gas.
The Traffic Light System:
The Traffic Light System makes diagnosis easy. Normal - no electrolysis, Amber - Caution you may
be able to see corrosion in a year, Red Serious - you will be able to see corrosion in 6 months,
Flashing Red - Critical corrosion is occurring now so immediate repair is advised. Watch the live
slide show at www.seabis.com/ click menu: Proof of Concept. The slide shows demonstrate the
SeaBis System.

How to Eliminate Electrolysis Corrosion:
Why we succeed:
The SeaBis System measures current through the metal being corroded, your installation, propeller,
hull, train controls, vehicle, street power or lighting. You use the SeaBis unit and Process of
Elimination to identify the cause and repair it.
Process of Elimination briefly: We disconnect wires until SeaBis indicates Normal. The last thing
we disconnected was the cause. Now follow Process of Elimination to repair / replace the cause.
ALL electrolysis is eliminated by the SeaBis System under actual live use conditions.
See seabis.com for Testimonials with method of contact and 3 year money back Guarantee.
Typical faults and repairs are included with the supply of the SeaBis System. The use of the SeaBis
unit is essential.
Repair the Cause of Metal Corrosion:
See Process of Elimination: preview available here. Common causes and their repair are included with
the SeaBis System Process of Elimination. See How to Repair the Cause of Metal Corrosion and
Typical Faults and their Repair. In the unlikely event you need additional support it is available at

Why does SeaBis succeed when a multi meter must fail?
A multi meter when used to measure current actually inserts a resistance in series with the circuit to
be measured. Doing so disturbs the actual resistance commonly by 100:1. So its chance of being
correct is 1%. In addition it actually measures voltage, not current so It has no chance at all of
eliminating metal corrosion. The SeaBis unit does not insert anything into the circuit to be measured.
SeaBis measures current as current without disturbing the circuit. So we achieve 100% accuracy. That
is why we eliminate metal corrosion with 100% success.
Why does corrosion occur?
There are commonly misunderstandings so I will start from the beginning:
Electrolysis corrosion is caused by electrical current. When we eliminate the current we stop the
corrosion:
An example:
Assuming you are sitting at your desk and the light is on. Voltage is supplied to the lamp by the
switch. Current flows through the lamp metal element causing illumination and slowly dissipating the
element. The metal element in the lamp is slowly dissipating in the same manner as electrolysis

How to Eliminate Electrolysis Corrosion:
corrosion of all metals. Holding a cloth so the lamp does not burn your fingers, and with the light still
turned on, you remove the lamp. The lamp goes out and the element ceases to dissipate. The voltage,
measured in volts, to the lamp socket: at 110 or 240 volts, is still applied. The current, measured in
milli-amps, through the element has ceased. There is no point in measuring voltage – it has not
changed. Measuring current will immediately show the element dissipation has ceased.
How do I know you are correct?
See www.seabis.com/testimonials.html for testimonials with contact details. Contact some of them. In
addition, I know of no other electrolysis elimination product with a publicly available 3 year money
back guarantee. See seabis.com Menu, Proof of Concept, there are two slide shows.
Still in doubt?
Ask any manufacturing jeweler how he plates gold onto a ring. The gold is your (installation / vehicle
/ engine / hull) - wet metal and the (jewelry)base metal is the Earth. The Jeweler dissolves the gold to
plate the base metal.
Myths:
"Shore (AC) power causes electrolysis corrosion". Very very unlikely:
Electrolysis corrosion is caused by electrolytic action between damp or immersed metal or cooling
system via any dry to wet contact to the Earth. Electrolytic action is particles of metal being dissolved
from your metal by battery current. Battery current is DC - Direct Current so always flows in the same
direction. So permanently dissolves metal particles, every hour of every day. AC (Mains power) is
Alternating Current so dissolved particles taken of in the first half cycle when current flows left to
right, will be replaced in the second half Hertz when current flows right to left. So AC cannot cause
electrolysis corrosion.
"Anodes will stop electrolysis corrosion". Even more unlikely:
A one kilogram anode produces one micro amp - one millionth of an amp, of protective current.
Electrolysis is commonly in one hundredth too several amps of current. So we would need a lot more
than 1,000 kilograms of anode! I have personally measured 9 amps caused by a VHF Transceiver with
a 9 amp power supply. When SeaBis proves electrolysis is eliminated then Anodes will stop galvanic
corrosion.
"Stopping electrolysis is too hard"
Only for those who make a living repairing electrolysis corrosion. 20 years ago electrolysis corrosion
barely existed because marine equipment was professionally insulated from all metal that could get
damp to wet. Today, larger tugs, military vessels, professional vehicles, most trains and larger aircraft
are correctly insulated (isolated) so do not experience electrolysis. Most experienced Professional
Fishermen know what not to buy. Unfortunately most Recreational and some Commercial and
Industrial do not. The SeaBis System eliminates ALL electrolysis corrosion, permanently. SeaBis can
be used to test before you buy.

How to Eliminate Electrolysis Corrosion:
The real culprit is Direct Current (DC). It is supplied from Batteries. DC carries metal particles, 24
hours every day, 7 days a week, every week of every year, permanently to the seabed or Earth. DC
flows in one direction only so continually depletes all metal in even other than dry contact with water
or the Earth.
There is a common misunderstanding the Mains AC, Shore Power, causes electrolysis corrosion. That
belief is incorrect in 99.9% of instances: AC is Alternating Current: It reverses direction every 1/100
or 1/120 second. So if it removes a particle of metal in the first 1/100 second it will replace it in the
second 1/100 second. Common sense. In the 99.9% and the remaining 0.1% the SeaBis System will
instantly identify the danger of corrosion and Process of Elimination will repair the cause.
How do I use SeaBis with multiple battery installations?
Where the battery banks can be connected together, usually for charging and reserve energy, use one
SeaBis connected to the House (major use) bank. When the other banks are switch in circuit SeaBis
will automatically interrogate them. See www.seabis.com/one-seabis-to-many-battery-banks.html
Where the battery banks cannot be connected in parallel, there is a choice of:
Using one SeaBis and moving it battery bank to battery bank:
As the current flows between any battery terminal and the Earth or (seabed) it is essential to
disconnect both battery negative and battery positive on those batteries not being tested.
OR
Using a switch, available from SeaBis and locally, for one SeaBis to be switched to many battery
banks. seabis.com/switch.html
OR
Installing one SeaBis per bank. This is the only method to obtain 100% and permanent protection.
SeaBis will instantly alert you should ANY electrolysis current occur. This is the only advised method
for Industrial, Rigs and Ships. We will discount the price of additional SeaBis.
My Rig has more than 5 battery banks, can you assist?
Yes. The cause/s is permanently eliminated by the SeaBis System. You do not need to buy more than
one SeaBis. Contact Glen Bishop: [email protected] or phone +61 (0)8 8552 4711 or we can set
up a World-wide audio / video link.
Multi meter - Why risk your life to gain absolutely nothing?
People die, regularly, from the hydrogen in batteries, exploding. That is caused by using a multi
meter. Never use a multi meter on any amps range in association with a battery.

How to Eliminate Electrolysis Corrosion:
Using a multi meter on any current range will not find the cause and is taking an immediate risk of
causing death by battery explosion. That is a bad way to die.
The use of a multi meter on voltage cannot find the cause. It will waste your time and money while
electrolysis corrosion will continue.
Using a multi meter on ohms cannot eliminate electrolysis. The multi meter uses a voltage far too low
to prove anything at one millionth of an amp. It will waste your time and money while electrolysis
corrosion will continue.
Using the SeaBis System is safe, extremely accurate and will eliminate ALL electrolysis corrosion
under live actual working conditions. Permanently. No coatings. We eliminate the cause. No through
hull penetrations.
Can I get assistance?
98% find Process of Elimination Instructions adequate to eliminate all electrolysis. However, yes. Email and phone assistance can be purchased at seabis.com/products.html. We will cooperate with
yourself and / or your nominated person.
The professional marine engine:
Manufactured but not promoted as an alternative, actually a modification, at time of supply. It is
considered mandatory for professionals with generations of experience. They have learnt the hard
way. Our alternative, is to fit marine isolated components and so convert a non isolated (insulated)
engine to a full marine isolated engine. The gauges and senders are available at
www.turotest.com.au and they are sourced from America. They are available from immediate stock.
Most starter motor & alternator re-winders can isolate the negative or replace the whole unit. Then
you have a marine isolated engine at 5% of the marine isolated engine additional cost.
3 year money back guarantee applies on completion of Process of
Elimination.
There is a 5% chance you will require assistance. If in any doubt: Glen Bishop: [email protected]
