Re: electrical drain killing battery - '98 Taurus
Similar problem, in that I've isolated a ~230mA drain through the battery saver relay fuse. I'm experiencing dead battery problems intermittently, most recently in only about 5 hours. If the GEM resets when the fuse is removed and reinserted, I haven't checked if it is resetting properly. The dome lights are not lit, and I can't see any other obvious drain.
Possibly related: In the morning after a heavy frost, the door mechanism felt frozen. More force than normal is required to unlock and open the door, and it seems like the cable or latch jams to the 'open' setting. I used a screwdriver to force the latch into the closed position, observed dome light off, and let it thaw. After thawing, the door appeared to operate normally.
I suspect that moisture freezing is causing the door latch to intermittently indicate 'open', waking the GEM and energizing the battery saver relay. I've got the driver's door torn out now so I can inspect the mechanism if if freezes in the coming few days.
Is there a way to test the electronics without spending 40 minutes holding a meter to the connection? Or an easy way to determine what the wake-up signal was?
Sorry if bringing up an old thread violates etiquette here.
