Electrical gremlins (headlights, tach)

[jrbonds]

Just got done rebuilding my car, yet again. Now I'm having some electrical issues. I will go through the harness, but was curious to maybe get a clue as to where to start looking. Here's what is going on:

1. All 4 headlights are on and very very dim and the blinkers.
2. Turn blinkers on, car shuts off.
3. Tach won't work
4. OPSU is pegged past 80 (luckily I have a mechanical gauge also)
5. Horn won't work
6. Massive battery drain


All this worked when I put new motor in and fired it up for the first time. Then found a massive problem elsewhere and dropped Kmember, fixed other issue and reinstalled motor.

THEN THIS CRAZINESS!!! Any of this tied to together somewhere? So frustrated. And yes, I put a new alternator on it last night.

Sounds like a ground issue -- something was either missed or broken along the way.

Hopefully it's just a ground. I guess I need to figure out where all my grounds are.

Could be a disconnected power feed or a short somewhere as well reading back through your question.

Check your wires underneath. Sounds to me like something may have been pinched or cut while re-installing the K-member.

I know the map sensor plug got pinched and I had to fix it. But I can't find anything else!!

No other wires at all? There HAS to be. Any corroded connectors? This sounds like one of those simple issues that stumps us at the same time.

Know what? Check for burned wires as well. Could have arced off the body or K-member.

I think along the same lines as these other guys....sounds like a dead short somewhere.
