QUOTE(Valy @ Mar 29 2012, 09:43 AM)  What else is always on? Clock? when I had battery drain issues last year, I traced it back to my nonworking clock. I simply unplugged the clock and that ended the drain problem. Warrenoliver |

Sorry for the delay responding. Unfortunately I do not have a clock or radio.
There are only two defective circuits on this car I know of. The left-front parking lights and the right rear turn signals. The harness power lead on both is dead and the lights are powered by single wires spliced to their proper source under the dash. The old are taped off. 30 years ago the PO rigged a two-pole generic flasher relay to power the turn and emergency flashers. It remains in place. |

Your drain seems a little high with no radio or clock. Do you have FI? The ECU will burn a little power when off.
