In this episode we tackle the common low voltage problem with the OBS (Old Body Style) Chevy Truck or "GMT400" charging system. Mine is a 1988 GMC K1500 single cab short bed with a 383 stroker and a Holley Sniper EFI. We use a multimeter to find some high resistance wires and bypass them with a new piece of battery cable and get the system charging at 14 volts.
