One wire alternator problem

100 amp alternator and an 8 gauge wire?

Where is your battery located. In the engine bay or trunk?

If it`s in the trunk, should the alt. wire be ran all the way back to the battery ? I have a chevy 1 wire, 130 amp alt. on mine w/ the ford relay on the firewall, and just ran it to there. Not proven , but seems right now that the battery slowly loses charge, even tho the handheld (fast 2.0 f.i.) says 14.2 what little time I have run it. Been in the paint shop all summer and just now starting to put trim and stuff back on.-------all comments welcome-----bob
