Electrical help
My truck battery is draining almost nightly. So far I've replaced the battery and alternator (needed to upgrade to an Interstate battery and a chrome alternator anyway ), and removed all external add-ons that would draw power, including the radio, alarm, etc. Still ... draining. I'm a little stumped, and not too mechanically inclined. Could it be the voltage regulator? Could it be an evil fairy?
Thanks ahead of time for any help.

Re: Electrical help
I actually think the starter IS shot. I can't duplicate the noise it makes in this post. But you get the idea. I bought some shims, but maybe I'll go for the rest. I'm going to do the fuse thing first, though. Thanks!

Re: Electrical help
If it was stuck points in the regulator you would have quite a spark when you disconnect the battery cable. It isn't a direct short to ground because you would have blown a fusible link or burnt the harness. A lot of these are caused by the horn wire under the steering wheel grounding and energizing the horn relay. If that was the case the horn should blow unless it has been disconnected. My .02

Re: Electrical help
So far it looks like the alternator I bought was a bad one. I exchanged it, reclocked that one, and installed that one. So far it starts right up. Now it sits for a few days. That will be the real test.
