So I finally have all the mechanical stuff out of the way. I hooked up *most* of the wiring harness (no o2 sensors because i have no exhaust on it yet, reverse lights not hooked up, but everything to make it run is in place, I think). I drop the battery in and turn the key for the first time - NOTHING! Not even the lights turn on. I thought the battery might be dead, so I charged it and tried again - same thing. Got the volt meter out and it has 11ish volts, until I hook up the positive terminal, and it drops to 8 volts. There is a ground somewhere, but I haven't the first clue where to look. Any suggestions?
