BMW battery draw
my 87 BMW, mint condition, I'm original owner, all maintenance & care
perfect, mint shape..However no Dealer can find the battery draw source and
a new battery didn't end this intermittent issue. Starts with a jump, might runs
then 2 yrs or two days. Battery tender only worked for a while.Any thoughts
where the draw can be?
i would replace the alt and ..and the battery again..if you have a draw only sometimes and cant find it...
Alt. is fine. It quickly starts on jump from totally dead.. Got a new battery again.Disconnected radio, and pulled fuzes..Ground, lead to battery is perfectly fine. Starter fine. 3 Dealerships Mechanics couldn't find the draw, spend 4000.00 already..Once started will run for weeks, months..or might not start the next day. Pulling out my hair.
$4000- what a story- how can they take the money and not fix the problem? I'm confused- but, whatever, this is not that hard- with an electrical tester- find a good independent garage- with a mechanic who can do simple electrical work-
Is it possible the "Service Indicator light"..(I took out that Fuze for the light yrs ago)..Maybe, it could be time again, after an oil change, or service, maybe it needs to be shut off again? I don't want to buy a $50.00 tool to shut it off.. (Service Indicator light) and the Tech I knew w/the service tool moved. Could that be why the sudden draw is happening again? The tender seems like it should works, (green light is on) I bought a new jumper box now and have to use it every day to jump the battery when I drive, but once started hold a charge.. It starts instantly (Battery is good less than 2 yrs old) it has a draw somewhere..It stays charged until I don't drive it for two days or more. Alternator is good, holds a charge. Starter is fine starts right up..when I hook it up to the jumper box.No a problem, lights work but won't start without a jumper box now...It just has this draw."somewhere". Anyone know why? It makes me nervous.
