the stock wiring is thin. its a bottleneck in the charging system if your putting a big load on the alt. if the batt and alt are fine, try upgrading the stock wiring. 4 gauge would be a safe bet. can anyone comment if 8 gauge would be fine to replace the stock grounds and the alt to batt power wire? should this alt to batt also have an inline fuse? the stock wire runs to the mega fuse then continues on. should the "parallel" wire to the batt be fused?
