Hi i'm having some trouble keeping the juice in my battery. heres my setup: 1991 Formula 350 converted to carb. stock wire harness is still in there, but i snipped the injector plugs off and covered the wires with electrical tape. not using the ecu either. i have a holley out of tank electrical fuel pump that i'm running on a switch. not the issue is that i'll start it up drive it, but after i turn it off the battery goes dead. any ideas or places to start checking for bad grounds or anything? any insight is appreciatted. thanks in advance.
