Alternator - Check my wiring please?

[Daydream believer]

IIRC, it means "I think you will find".

Thank you- spent ages trying to work that one out
& IIRC ---- have we changed from Portsmouth yardstick ??:ambivalence:

You really don't need to replace it at all, if the positive is fused.

+1 Would be pointless. If it had not been present the pos fuse would have blown.

Because looking at the first photo it appears that the red wire is something added. Its does not seem to be part of the original wiring.

I think you should find out where the red wire goes and determine what its purpose is.

It was just tied up behind the unit. I think it was to go to a second alternator. I.e. to trigger both alternators to work from the same warning lamp lead.

Ok guys the problem is solved. The main negative feed to the alternator had a fuse in the line which had blown. See below.

Question: I don't have a replacement for this. I think inmust have touched the positive to the nagatice and blown the fuse during installation. If I temporarily install it without the fuse, will this be ok and as an fuse the negative lead normal?

P.s red lead for the warning light was not going anywhere it seems. I think it was for a second alternator which the original owner had running in tandem.

Hi. I have just come across this thread. I recently posted here about this type of fuse in the negative feed. Mine had broken both wires due to vibration I guess, and I must have run the engine for hundreds of hours without any problems as far as I know (AFAIK) it's all reconnected know. So who knows what it does?
