Hello dear elk friends! I hope one of you can help me so that I can save the expensive and unfortunately not always omniscient ones. Unfortunately, the only topic that already exists to my problem does not help me. To the problem: my 850er station wagon, 170 HP gasoline, automatic, trailer coupling, BJ 1996, no additional installations sucks between 0.4 and 0.8 amps (!) out of the battery. I checked that so far: measuring device between minus pole of the battery and the black cable. Shows in average 0.5 amps. All fuses in turn pulled, all relays in the box of the series pulled, starter clamped, Lima shut down. No success. Then I cut the plus cable strand on the battery coarsely, with the result that the current over the seven (?) merged, thin cable disappears. The thick, red Kable and the single thin take nothing. Only the cable strand, which then disappears somewhere in a flex hose pulls the whole electricity. Although I have a circuit plan (Haynes) here, I don’t have to worry about the hook up with you?
