Make sure all funky courtesy lights are off. Glove boxes or manual reading lights for the rear passengers in some cars will stay on and that's all it takes. You may have a hood light too. Just take the bulb out for now. If nothing found quickly then it's on to isolate which circuit has the drain and one that fast should be fairly easy to isolate but then the fix is unknown you just know which circuit and we go from there, T Hammer Time Ultimate Carjunky / Moderator Aug 21, 2010, 4:03 PM Post #3 of 4 (1433 views) Re: ELECTRICAL DRAIN Sign In There is a procedure for finding a battery draw like that. You will need a digital ammeter and a jumper wire with clips on the ends to do this. First rig any door switches so you can have a door open without triggering the interior lights and unplug the hood light. Remove one battery cable and attach the meter in series between the battery cable and battery post. Take the jumper wire and also attach it the same way. Leave the jumper wire on for at least 10 minutes to expire all the automatic timers. Now remove the jumper wire and read the meter. Anything over 50ma is too much draw. The way you locate this is to start removing fuses one at a time until the meter drops to normal level. This will be the circuit with something staying on. Determine what components are part of that circuit and check them individually until the problem is isolated. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. cmatteliano User Aug 27, 2010, 10:08 AM Post #4 of 4 (1414 views) Re: ELECTRICAL DRAIN Sign In I had a similar problem with my 72 Eldorado and it turned out to be the analog clock in the dash board. When I disconnected the clock, the problem went away. I think many of the Chrysler products use analog clocks and could contribute. Other than that, i would agree with the procedure of using a meter and pulling one fuse at a time until meter reads no current draw and then isolate from there. I am currently working on a dead short on my convertible top, horn, seat circuit that is also giving me a fit trying to isolate.
