Fuse #23

[sandfra1]

I have a 1990 BMW 525i it runns but drains the battery I have a hot wire and took it to the dealer who said its fuse 23 which according to them is in the dash they did not know where and stated they had to remove the dash to see where the wire is and it could cost up to 3,000. This seems alot so it has sat for a year in the driveway. now it is time to dump or fix. can any one give some light as to what exactly fuse 23 controls in this model?? I can see 2 things 1st is it has no radio the last owner striped it out and the wires are not the culprit per the dealer but they are not taped up, 2nd in the stACK of reciepts i see some about the heater. The car runs fine but the day or so after putting in a new battery it needs a jump.

I thought Fuse 23 was the fuel pump... on the 535i anyway...

bentleys mnanual would cost around 60 dollars and decent multimeter 20 dollars US... get those and dive in yourself <- good advice

Fuse F23 is the fuel pump fuse, it is in the front fuse box, and is only energized when the DME asks for it, so hardly can be the culprit unless you have a seized or contacts soldered Fuel Pump relay (in this case, your pump should be about to die on fatigue).

It is easy to hear the pump running (hissing by the right rear wheel) remove the fuse and confirm it is not there anymore. But again, I doubt it is the culprit.

Well the fuel pump seems fine car runs but still a drain, i am glad i did not let them tear out the dash, will invest in a voltage meter, have the bmw shop repair manual on disk guess i'll do some more searching. Thrying to get it done and repainted before my husband gets back from iraq.

Sounds like they heard "blah.....blah....blah....electrical drain.....blah.....fuse"

And said "its in the dash, lots of money, don't feel like hunting down electrical problems"

Should update your profile (if you want) to add in your location. Maybe someone here is nearby and can help out.

Good idea.
Just let us know, and probably someone can help you do the checking.
Might be much faster and better if someone with experience in electrics starts with the testing.

hey i finnaly got it to an electrician, replaced the battery again because the first was so fried it would not charge. for 1 wk and 70 bucks they detirmined that thier was no problem no draw and the car now starts all the time the battery never dies. humm..... seams like they saw a female coming.

I'm glad you got your car fixed.

I don't think that your gender had everything to do with it. I've worked at or with car dealers for over five years and in every dealership it's the same story: "How much money can I slam this client for?" They don't care whether you're black, white, female, or male... they want to make $2000 off of you.

That's why this community is such a great resource... we share info with each other and save each other thousands.

Readers of this forum not only save money, but also a lot of aggravation of having to deal with the dealerships. Although in my case it costs me a lot of time because I don’t get anything else done when I’m on bimmer.info, I just keep reading and searching and reading and searching...

try to get a volt/ohm tester, ther arent expensive these days. I can get one for about 10 bux and it can tell you digital voltages for the battery voltage when engine is shut off and running. There is a possibility that one of the diodes in the alternater is leaking which can cauce a dead battery situation.
