Andy, Have you replaced the starter? It's almost 30 years old and the older it gets the more current it pulls trying to start. Work shop manual, M:02:04,,540 amps locked up pulls volts down to 7 volts, 260 amps pulls down to 9.4 volts. So if your battery is rather new and fully charged you could tell the current drain of the starter by how low the battery volts drops. The older the starter get the more current it takes to start. It may be the starter.

By inserting a digital multimeter in-line with my battery, I determined that my Lockzilla draws about .01 A while sitting (drops to zero when Lockzilla is disconnected). In addition, I have a stereo system with an amplifier. The amplifier, when isolated, seems to be drawing about .03 - .04 A with the key out of the ignition. The draw is constant even when I remove the remote and speaker leads from it. The amp is not on as per the LED's on it, but it is definitely pulling some power. When I disconnect this amp and the Lockzilla, my DMM fluctuates between 0.00 and 0.01A (I can't find that last half-amp by pulling fuses, maybe the meter is a little off) and when both are plugged back in it reads about 0.05 A. Is this enough juice to drain a battery in less than a week? I have not put a meter on the battery to read the voltage after it sits for a week so I don't know how low it's getting, but certainly low enough to not turn over. I know it's not exactly DeLorean related, but the amp is a JL Audio 250/1 monoblock amp for a subwoofer. The instructions don't give a resting draw, so I'm wondering if that is typical? Seems a little high, so aside from an internal problem with the amp, what else could go wrong with it?
