Wire size guidelines:
The components are shown in relative positions, but have been spaced for clarity. The Megafuses
should be placed as close to the battery as possible to minimize unprotected wire. All of the battery
cable and heavy wire runs should be kept as short as possible and should be protected from chaffing
or mechanical damage.

Be sure to use a ground strap or braided cable, of the same gauge or heavier than the positive cable,
from the battery to the frame. It should be securely attached to a welded or threaded stud, and the
ground path must not be interrupted by paint or powdercoat. A secondary ground cable (#4 Ga. Or
heavier) should be run from the engine block to the frame. Finally, if your alternator has a tapped
boss on the rear cover, attach a ground cable (#8 Ga. or heavier) using a short bolt and attach it to
the cylinder head. Each Powercell ground (see Powercell schematic) should be securely attached to
the frame as close to the Powercell as possible.

*Note: Values are suggested based on generic
requirements. Actual required fuse size may
differ from those listed. Base fuse selection off of
smallest wire gauge connected to the output.
Rule of Thumb: If your tail lights have
yellow on them, then they are multifilament.
If your tail lights are red ONLY, they are
single filament
