Question Power drain

I have a problem with my 69. The battery keeps getting drained and it seems to be coming form the charging system. Does anyone have a schematic for a 69 rag?

Re: Power drain

Im currently rewiring my 68. Though I know very very little about wiring (I've got a former chevy mechanic giving me a hand), I do know that if there are any aftermarket upgrades or accessories poorly spliced into the system, this could cause all sorts of problems. For example, alarm systems, stereo systems with multiple disk changers, etc. The main reason I decided to rewire the whole car is get around power drains and ignition problems. Sux to take a girl out in your cherried out muscle car.......and it dont start.

Re: Power drain

Murray, have you tried the old test lamp trick? Disconnect one of the battery cables (ground is a safer choice) and put a test lamp between the battery post and battery cable to complete the circuit. Your electrical drain will cause the lamp to glow. Then you can begin disconnecting parts of your harness, pulling fuses, etc. until the lamp goes out. If you suspect the charging system, try disconnecting the red wire from the alternator or voltage regulator to see if the light will go out.

If you do a search in the electrical forum you'll find several links to schematics. All first gens were essentially the same. Accessories like RS headlamps and AC are in different drawings but I think you'll find those as well. Also, someone posted some color schematics that are quite popular - check the sticky topics at the top of the Electrical forum. The moderator will send you a free password to unlock them.

Re: Power drain

The lamp test is a great start, and is very valid.

There is a thread in the electrical sticky on "trouble shooting the external reg charging system" that gives a bunch of info that will help you determine a problem.
