I believe the red wire in the loom that you are seeing goes to the fuse panel INSIDE the coach. If this is the wire that you are describing, then the end that you are looking at goes to a large terminal on the blower motor relay. From that same blower motor relay terminal there another 6" wire that goes to the isolator. That wire to the isolator is a 16 ga. fusible link.

I hope I am describing the wire you are asking about.


hi Ken-

I have two red wires coming out of the loom...one clearly marked DIODE.

The pic below shows the same DIODE wire coming off the frame to the right.

I think the wire you are referring to is the one I'm holding in the pic below?

also, am I mistaken that the red wire I'm holding goes to the horn relay, not the blower relay? (I thought the blower relay is the one above it)

How is your alternator wire run? Through the loom?

also, please notice my beautiful waterproof heat shrink and terminal work.

I believe that the red wire that you are holding is the one that feeds the fuse box inside the coach. That wire in the picture is currently connected to the correct place on the front of the Blower relay. If I said horn relay in a previous posting then I said it wrong. It should be the blower relay.

On the picture with the large single terminal with the big 1/2" nut on it, the little black wire going off to the lower right is the fusible link.

I can not give you the correct OEM alternator wire routing from the center terminal of the Isolator by looking at my coach. This is because my coach had an engine fire 7 years ago. I replaced all of the wiring on the top of the engine at that time. So mine is not stock (OEM).

The GMC wiring diagram says the alternator wire is a red 10 gauge one. I believe the one you are holding is a red 12 gauge one.

Someone else here will have to comment on the wire routing.
