355 Battery/Alternator Warning Light

That's probably what I'll end up doing as there are no new harnesses available. I though the previous owner spliced in a new plug close to the alternator and I kept cutting back the wire to where I thought the join was, but there was none. It seems to have a solid rubber moulding around the conductors all the way to the "V". I cut so much back, it's now impossible to splice in a new section without proper access to the harness.

I'll string in a temporary lead (using a different routing). Hopefully I can avoid the spinning parts of the motor (and the hot ones), until the next engine out.

 

Here you go. That small 3 wire harness goes up into the valley, branches to bank 2 side, and then goes to the back of the car. If you remove the coolant tank, the fuel block, and the power steering mess, you can find the wires with the engine in. It's not a fun job, but the engine does not have to come out. Good luck.

Great pic. Thanks. Perhaps possible, but I think I'll make it easy for myself and wait. The AC compressor wiring also seems to run down the front of the engine (that's also part of the loom).

I'm not entirely sure if the original harness had solid 3 core wiring. Looking at your photo, perhaps not. On my car, the wiring starts as easily separable individual wires at the main plug (behind the left hand strut) and at some point, the wiring changes. I think it would be best run in some standard individual wires with some heat resistant sheathing to make repairs easier in the future.

I just received a replacement plug for the alternator in the mail. It has some very thin wires pre-pinned. Possibly 0.5mm^2. The original wires at the other end of the harness are 1.5mm^2, and quite robust. I might get a plug kit so I can fit some thicker wires.

All this fuss over a broken pin
