Help!!!! battery shorted but car still dead

Phylis · 11-27-2010, 08:14 AM

Can anyone help please!!!

I was doing someone a favour and giving them a jump start.

I managed to short out my positive to the bodywork whilst attaching the lead.

Now my car is completely dead. The old battery was a dead short so I have replaced with a new one which is fine. Measuring across it when connected up and it's normal voltage etc.

I am guessing something else has tripped and needs resetting or something. Is it a main fuse for the E92 or some kind of circuit breAker or something?????

Any help gratefully received!!!!!!!

maybe the fuse?

I suspect you blew the IBS cable.

money is on the IBS cable as well.. i'd check the fuse too if you shorted..

I once didn't help a woman who needed a jump because of this situation. The other person is on the road and happy, but the BMW is now facing hundreds of $$$ of repairs.

There's no way the engineers wouldn't design for the possibility of messing up with cables, so hopefully there's some sort of fusible link that burns up and can be replaced.

Not to be funny but I know the IBS isn't something that a person would just happen to have a spare of. What fuse are you talking about?

Can anyone tell me how to find the fuse plse? I have looked everywhere on the Internet with no luck!!!

Also, what's the IBS cable and is it easy to replace? Expensive??

Many thanks guys

The car is a 2007 E92 330i Coupe BTW

Think I may have found problem. Apparently the power distribution box has a fuse. I just need to test continuity to see if it's gone. Can't see that it can be anything else to be honest.

You won't find the fuse on the internet. The internet doesn't have any fuses. You'll find fuses in your car though

The IBS is integrated into the battery cable. You should find a good local garage to troubleshoot and repair it. Unless you are very tech savvy this isn't a job for you. It'll be a several hundred pound repair.

IBS sensor is several hundred pounds? Maybe get a buddy or two to help lift it out of the trunk then.

Are you being sarcastic? The OP is from the UK....

This is why I don't give jumps using my car. I bought a jump start battery for 50 bucks that works great. I have seen several cars develop problems during jump starts. Sorry for the stupid jokes when you are trying to get a straight answer.

I think (hope?) that he was making a joke along the lines of my "there are no fuses on the internet" comment.

Just an afterthought..maybe best place to attach the jumper cables is right to the battery terminals in the trunk?

Nope - that is always a bad idea - unless you disconnect both cables from the battery first.
