I am replacing the alternator on my 93 xj6, The person who owned it before me fried the old one, I just want to double check the correct wiring before I install the new one, Not sure if the person before me had it hooked up correctly, There are 3 connection points, The Plug, The lg main terminal & one more small wire, The first 2 are obvious. On the alternator there are 3 small nuts that hold the shield on, one of these has a piece of metal held on by a nut & a phillips head screw, This IS NOT where they had the small wire connected, it was connected to the other small nut, Not sure if that was correct, I would think it would connect to the phillips head screw ???
Thanks in advance for any help.

Hi shoeboy,

Welcome to the Forum.

I looked for your introduction, but didn't find one. You really should file one.

I have an '88, so looking at mine isn't going to help you.

Perhaps we can figure it out. Here are Hayne's wiring diagrams of the XJ6 starting and charging systems.



There are two types. I am assuming yours is on the right.

However, it shows 5 wires with 4 connections to the generator; not counting the ground.

You should have a

1. WHT/YEL coming from FUSE 1
2. WHT/BLU to the INST PACK
3. BLK coming from the STARTER
4. BRN coming to/from the SUPPRESSION MODULE and
5. BLK coming to/from the SUPPRESSION MODULE

Is that what you find for your Cat?
