WTF is up with my battery???

[TxAg98]

Ok, so my battery died and I finally got the car started to open the doors and get to it. I find a pretty good mess. BTW, car is a german spec 1991 525i

First picture: Wire coming off of positive terminal.



Second picture: These two wires are coming out from somewhere else in the vehicle. The red one has an end that matches up with the red coming off the pos terminal in the previous picture and the black wire looks like it should have been connected to the negative battery terminal



Third picture: Here is a closeup of the black wire. The end is busted, but should it be connected to the negative battery terminal?



4th and final: The two red wires can connect together but seems like there should be a fuse or a spring or something to make the conncetion tight. The connect with like a 1/4 turn, but the connection is very loose.



All these wires are exactly the way I found them when I removed the back seat and prior to removing the battery. Only aftermarket electronic on the car is an aftermarket stereo. Can someone decipher all this and tell me if I need to connect some of these?

Thanks!

Those wires are most likely for audio or maybe if it had a mobile phone in the vehicle.

Wow! If your car all works fine leave well alone and tape them up, could be anything , aftermarket, alarm, playstation port, tow bar,which have been removed, loads of options. as the saying goes " if it dont need fixing, dont fix it".

As for your battery died, I presume from old age not a drain?

Old age I guess. Its a 91 that I bought about 3 weeks ago. Everything seemed to be ok until we got our first cold snap. That morning, she cranked about 3 times and went belly up.

Ok, If all is ok with the car and electrical system tape up those wires, and buy yourself a new battery, BM's dont like old batt's.
