I just pulled the tranny out my 69 camaro, and when I looked under the car I saw a broken orange wire. This wire was in harness with a yellow wire and a purple wire. The purple and yellow wires go to the starter. Would anybody have an idea where the orange wire goes??? I tried my headlights for the heck of it, and I get nothing. I also tried to see if the starter would engage, and no power. Any help or ideas is greatly appreciated.

some things to check:

Did you remove the battery cable before doing the work, and if you did, did you hook it back up?

Did you make any sparks while you were under there?

Use a voltmeter to check for the voltage on the connector screws on the horn relay, should have 12 volts. If you don't, check the little wire that comes off the positive battery cable. It attaches to a small junction block behind the battery.

No I did not unhook the battery, and I didn't get any sparks.
I went to check things out and my battery is reading 10.6 volts. The weird part is I did a resistance check from my ground wire to my hot wire on the battery. And when I turn the ign switch on I get less than 2 ohms. If I turn my headlight switch on I get the same thing. So it looks l like I got a short somewhere. With nothing on the resistance seems fine. The only other thing I did to the car was drop the gas tank to run a fuel return line. I'm a little stumped, if that one wire coming off the sending unit is shorted to ground would I only see this when try to turn something on?

If you have a door open, the following, singularly & combined, could be the 2 ohms:
1. Dome light(s)
2. GEN light
3. OIL light

If the tan wire was shorted at the tank sending unit or through its route from the trunk floor to the unit, then the gauge would read empty. If the black wire was ground, gauge would work as normal.

My fuel gauge is reading empty, but the tank really is empty. I dont have the dome light hooked up. The battery volts goes down to 2-3 volts if I hook it up and turn on the lights or ign switch. There is a wire going through the trunk which I thought was the tan wire from the sending unit, I unplugged it from the connector and still get the short when I turn anything on.

reading resistance across the battery cables (disconnected from the battery) is not going to tell you much. 2 ohms with the headlights on is probably pretty normal. If the points happen to be closed, 2 ohms with the ignition on is not too far off either.

You need to start at the beginning.

Disconnect the battery, and check the battery voltage. If it's less than 12.5, charge the battery. If it won't read 12.5 volts disconnected after being charged, take it to any auto parts store and have it load tested. If it fails, get a new one.

While the battery is out of the car, eyeball the wiring. There will be a small wire and a big one on both battery cables.

The big positive wire goes to the starter.
The big negative wire goes to the engine block, normally the alternator bracket on a 69.

These 2 wires are ONLY used to turn the starter, they have nothing to do with supplying power to the car.

The small wire from the negative cable attaches to the inner fender or rad support.

The small wire from the positive cable attaches to the lil junction block on the rad support.

The second wire from that junction block goes directly to the screw terminal on the horn relay, and also to the alternator, and the #3 connection on the voltage regulator.

The second wire off the horn relay screws is the main feed to the fusebox and headlight switch.

Do a physical check on all these connections, then install a proven good battery and do a voltage check on them.

Ok, I'm an idiot. It was an dead battery. I guess I was thinking the worse when my headlights would't come on. I didn't start the car but all lights work. I recently put a turbo(t-76) on the car. Everything went pretty smooth at first then I started to break parts(tranny, u-joints, bell housing, distributor rotor) and it seem like when it rain it pours so I guess I was just expecting the worse from the car. The car never had a problem before with killing the battery. Thanks for the help guys!!!!
