Hey all! I've got a 79 350/350 combo and I have not been able to solve this very odd electrical problem I'm having.
My car has no power whatsoever...unless I'm attempting to start the engine.
When I go to start the engine, my headlights come on, the GEN light comes on, the car will start and it will turn over and stay running, but ONLY if I keep the key pinned forward like I'm trying to start the car.
Naturally I don't do that for more than a few seconds because that'll hurt the starter, but it will run and I do have power nonetheless. The GEN light also disappears once the engine is running.
I've replaced some essentials since I've had the car, since the guy before me was using a screwdriver instead of a key.
List of new parts:
CVR mini starter
PowerMaster 140A alternator
Ignition Lock Cylinder
Turn Signal Switch
Ignition Switch (not AC Delco original)
Replaced glass tube fuses
I'm pretty sure that's everything I've replaced thus far, as far as electricals go.
To compensate for the higher output alternator, I upgraded my main wires to 1/0.
I've removed and taped off the old BAT+ wire from the old alternator and replaced it with 1/0 (fused) that runs directly to the positive side of the battery, instead of back to the junction block.
My grounds are: engine block to frame rail, frame rail up to the battery, and fender to the battery.
On my starter, I've got the positive battery cable and red wire on one lug, and on a separate, tiny side lug, I have that tiny S or R wire.
I found a diagram and my ignition switch is wired correctly, and I also have all of my detents on the switch, and the key will return to the RUN position as it normally would.
I sincerely do not know what to do now. I've got an AC Delco ignition switch arriving tomorrow, just in case mine is faulty, but if that doesn't work, I'm totally lost.
If anyone could give me a hand here, I would be extremely grateful. I'll attach some pictures to get a visual of what I've done so far. If anyone has any questions for me, I'll do my best to provide the answers. Thank you very much in advance!
