e30 won't start

[Ceeker]

ok, I removed the bolt off the power block on the fire wall and saw a spark. Upon putting it back nothing seemed out of the ordinary except my car now cranks but won't start. My car is meticulously maintained.

Would anyone know what might be the problem? I checked my fuses in the fuse box and nothing seems blown.

Any help would be appreciated. thx.

have you tried turning the key yet?















but seriously, check fuses better...

Check the fusible link in the small cable from the battery.

ok, how does one replace this fuse? I believe it's inline correct? do you have to cut it out and solder another one in?

[jlevie]

What I do for a failed fusible link is to splice it out and use a 60a lug type fuse. You can bolt one lug to the power point in the engine bay where the small cable terminates and then bolt the small cable to the other lug.

Yeah, but wouldn't that mean running like 6 feet of wire? (grin) wouldn't it just be easier for find a car with a 50a fuse and cut like a foot section out and solder and heat shrink?

Nope. You cut out the fusible link and splice in a short piece of wire. On occasion is is possible to just splice the cut ends back together.

so do you mean to transfer the fusible link to the front near the firewall for easier accessibility and omit it from the rear?

sorry, not sure I follow.

[jlevie]

Yep, because that is the eaiset way of fixing a bad fusible link.

[Ceeker]

Yeah, makes sense. I don't know why bmw put it to the rear of the car. I'll check it out tomorrow. I have a spare from my IX still in the car. Probably cut it out and solder it in tomorrow. thanks for your help.

[Ceeker]

Well, with a parts car and some solder connectors the splicing is done and the car now runs! Thanks for all your help fellas.. I greatly appreciate it.

cheers. Ernie

Nope. Hit your local car stereo shop and grab a 8GA AGU type fuse holder and replace that fusable link with it. Carry a spare fuse and life is good.

sure, that's probably a better/another option. but this didn't cost much and it's back to original. Good to know.
