Some electircal problems. Please look

[Crazy 13immer]

I did my RSM's the other day and since then I've had troubles.

I was on my way to school and got stuck waiting for a freight train, I turned the car off and when the train passed and the light turned green, I tried to start the car, but there was nothing, no dash lights, radio, hazards ect... I pushed the car to the side of the road and opened the trunk. Both terminals were connected, but the positive was pretty loose and I pulled it off and reconnected it. The same problem happened later that day and I took out the bmw supplied 13mm wrench and tightened it down. It was fine until today.

I got off of work today and I got into my car and the window did the roll down thing and when i closed the door, it rolled back up. I go to start it and everything dies. Radio, Dash Lights, Ect.... So I'm thinking that it was the damn terminals again and open the door and the hazard lights that I put on, turn on. I close the door and try to start the car and everything dies.... I open the door again, and slam it, and everything comes back on.. dash lights, hazards, radio ect... I start the car.. it was not as quick as normal, but it still turned over fine.

I have NO IDEA what the problem is and especially how slamming my door could possibly affect it.

I need to figure out what is wrong with it, I guess it is just one more to add on to the list of things to do in my restoration project.

Thanks for any help

EDIT::


After some searching, I read that it could be my alternator? And or corroded terminal connections. Can anyone confirm?

definetly sounds like a loose/ corroded connection somewhere.... but tracking that down could be very tedious.

[erobinson]

Maybe you need a new battery. Possibly the shock of the door created a connection on the battery.

[Crazy 13immer]

The battery is new-ish. Less than a year... probably close to 6 months. I'm going to take some steel wool to the terminals/connectors tomorrow morning. I really hope it is as simple as that, but I'll try to post a follow up.

[Bimmerbudday]

I've been having the same problem! but less frequent... probably like once a week. let me know if you hear of any solution or cause.

[kjprince]

yea same here on my 95 M3...but i have a whole list of strange annoying problems like this so i just forget aobut them... chances are it cant be cost effectivly fixed....check to make sure you have all the correct fuses with the correct amps in each spot. after that is a wild goose chase goodluck

Since your checking things, check the voltage regulator.


I have an 80A alternator for sale if you need one, check link in sig.
