exeliot Posted December 13, 2003 Share Posted December 13, 2003 Battery on my 93 SC400 goes dead if the car isn't driven for week to 10 days. What might be drawing the power? Quote Link to comment Share on other sites More sharing options...

AWJ Posted December 13, 2003 Share Posted December 13, 2003 My car did that a couple times last year after we first bought it. The last time it did it - I cleaned the terminals up real well (even thought they didn't look too bad) - cleaned the main cables as well. Jumped it, let it idle a while, took for a spirited drive, let it idle down and it hasn't happened again. Quote Link to comment Share on other sites More sharing options...
SPORTcoupe300 Posted December 15, 2003 Share Posted December 15, 2003 took for a spirited drive I love those! You can go to a mechanic and have them test the electrical system for power leaks. Basically they check if any amperage is drawn from the battery while the car is off. I once had that problem in a chevy and found out that it was a wiring problem with my alarm system. It was only sucking about an amp but over a few days it would discharge the battery. Quote Link to comment Share on other sites More sharing options...
JRFiero Posted December 15, 2003 Share Posted December 15, 2003 When I first bought my 93 SC300 the salesman told me the steering wheel memory (or some other electrical part of the steering column movement thingy) would slowly draw from the battery when the car wasn't used. You can shut it off with a switch on the left side of the column. Don't know if it's true, just passing it along. Quote Link to comment Share on other sites More sharing options...
Bubbles Posted December 16, 2003 Share Posted December 16, 2003 When you turn off the car, the trunk cd player is on, alarm could be on, the remote door lock is on and I think the trunk switch (if it's electrical) is on. The horn works too :whistles: It is possible to turn off the remote door lock with the switch below the steering wheel. Same goes for the trunk (at least in my 92).

jlee44993 Posted January 9, 2004 Share Posted January 9, 2004 Exeliot, I am on here tonight looking for anyone else who has experienced that same thing. I thought my alternator went out yesterday. Car wouldn't start and had to have boosted twice. I took it to my mechanic today and he said it was a power drain zapping my battery. The 12 disc changer was the culprit. He unplugged it somehow for the time being. The quote for a new changer was $800. Does anyone know where to get one for cheaper, or where I could send mine to have it repaired? Thanks and good luck Quote Link to comment Share on other sites More sharing options...
Lex Luthor Posted January 9, 2004 Share Posted January 9, 2004 Usually pretty expensive to fix them, i'll let you know if I spot one for sale. Quote Link to comment Share on other sites More sharing options...
