79, 351m. we dont have any lights or dash the only thing we have is 3 after market guauges in the truck, but the original wiring harness is still there. I am having trouble starting. New starter solinoid, new ignition box, new voltage regulator and new starter (we had the new starter bench tested in front of us before we bought it).We also have new battery terminals and good battery wires. On the voltmeter the battery shows around 13 volts, when we go to start it it sound like something is drawing and so the battery dropped down to 4 volts. If we jump it off it will run fine and it shows the battery is charging. As soon as we shut it off and try to restart, it sounds like a dead battery.
