Electrical short

I thought it was in my courtesy fuse, but i find that fuse is hot all the time, but will try removing all the fuses to see what happens.....

Although I never did this YET (I think I may have a power drain too, but my car is on a 'trickle charger'), here is what I read on a previous thread.

1.) Disconnect the negative side of your battery.
2.) Install a test light between the negative side of the battery and the negative battery cable.
3.) (If the light is on, you have a drain.)
4.) Unplug all of the fuses on the fuse block. (Hopefully the light will go off at this point.)
5.) One at a time, plug a fuse back in place, and see if the light comes on. (Note which fuse it is, leave it unplugged, then go to the next fuse.)
6.) Hopefully most fuses have been plugged in, and the light is off. The remaining circuits (the ones that cause the light to come on) are the one(s) with the power drain.

The clock will cause a small drain. You can always disconnect it, and see if the clock circuit still has a power drain. Also remember that a 1977 had a car alarm system installed, and this may be causing a drain as well.

I have a 1966-1976 manual at home. Most of the wiring diagrams are pretty much the same for a 1977. (I own a 1977 myself.) If you narrow the drain down to a particular circuit, perhaps I can help trouble-shoot further.
