[dhall5483]

I have a 2001 Holiday Rambler Endeavor with a Cummins and the ALT Charge light is on and I'm not getting a charge back to my batteries I have checked the alternator and its not putting out a charge and i have been told that there is a fuse on the exciter wire and it maybe blown is this true and is so where is it located its much easier to change a fuse than an alternator



Thanks for any help

Alternators seem to be a high failure part.
Have a reputable alternator/starter shop check it.... (and rebuild yours if necessary)

There may well be a fuse that stoped your alternator from working but unless someone was messing with the wires, at or near the alt. or fuse, it shouldn't have blown for no reason.

As mentioned by mel s, any alternator shop can check it out.

Same thing happen to me 2 years ago. No voltage being generated.

Took it off and took it to an alternator repair shop and had them rebuild it, cost was ~$185 and they had it done in 1 day.

Considering the duty cycle that the alternator is put through I'm surprised they last as long as they do. One of the tings that I read is that if your house batteries are depleted the alternator has to work that much harder to recharge them. The recommendation is not to have the inverter on when you first start out from an overnight stop to give time for the batteries to recharge and after a while turn it back on.

The exciter wire voltage comes threw the alt. lite.This energizes the field circuit starting the charging system.Lite is on therefore pull the altenator and have it repaired or replace it.

I had this happen 2 years ago. Solar panel got me 150 miles home. I called the leece neville rep. He said start at the alternator checking connections and work backward. Guess what, the wire that controls alt fail was broken at the alternator. Makes me wonder how many alternators get rebuilt just because of a broken wire. this wire had a lousy crimpon connector.
