Quick Alternator wiring question (black and white wires)
« on: February 09, 2022, 07:22:23 PM »
Hi
I usually take pictures before dismantling anything but the pictures are not clear enough to take the risk.
On my coupe , there are three black and white wires that plug to the alternator.
TWo are much thicker , one thick is bolted below and the other thick was bolted above (b+).
Problem is that there is a smaller black and white and I m not 100% sure that it plugs along the big one.
The below bolt was not removed and I didn’t remove any other bolt but I don’t want to take any risk.
Do you confirm that both wires are bolted on the bolt above ?
See pictures :)

On One of the pictures, I put them along on the same bolt. Seems obvious but once again, not taking any risks. Electrical diagrams are not really helping as all the ones I found seem to differ connection count wise.

Thanks

Hi
Much appreciated :)
So before I saw your pic I checked the following:
- upper big black  and white seem to go to fuse box (and is not at doubt)
- smaller one joins the big green positive from battery on the starter
- Lower big black and white it earthed

So , and your pic seem to confirm, the smaller one which go to the starter is connected to the B+  ?
