What makes you think it's not charging? I guess you are not seeing voltage on the dash gauge . . . but the gauge could be the problem. Have you put a clamp on ammeter on the cable from the alternator?

Have you put a volt meter on the battery when the engine is running?

I hooked up all the wires back the way they were when they came off. I used my fluke meter to check at batteries while it was running and I also checked on the back of the alternator itself while it was running.

If it worked on the test fixture, then it has to be wiring or sojourn connected to the wire that is bad.  I was going to ask if you took pictures before removal,  but if it didn't work before,  there is no guarantee it was wired correctly when you got it.  Do you have a wiring diagram for the alternator? Besides the large cables, you should have three smaller wires, often gray, yellow & red.   Is that what you have?

Yes.....that's her. I used my fluke to test while she was running with wires connected and without. Nothing. 

Yellow was on remote, gray was on the ground and red positive. 

I have every piece of literature of every component in this coach. 2 sets of schematics. I see where they're are the three posts but I don't understand how they work.

Yes...the fault light was on on the dash which made me think....no problem. I'll check the alternator and have it rebuilt if it isn't working. Brand new interstate house batteries and 31a screw tops for the chassis. The previous owner passed away and she's been sitting for a while....how long? I'm not sure.

Hi all, 

I'm a new owner of an 2001 executive 43ds. A 500hp cummins with an Allison 6spd. She's in decent shape for her age but I have to be honest. When it comes to electrical.....I'm not the greatest but I'm willing to learn.  I bought her to use as a second home while I'm out on job sites working instead of renting an apartment. Plus, I hope to one day retire and I wanted to travel......a win win right? Wrong!!

I'm an old mechanic and I can understand schematics (somewhat) ....

The coach cranks and runs fine.....but she's not charging. I took the alternator off ...a 200 amp leece neville.  Had it rebuilt and reinstalled it......nothing. I watched the man bench test this alternator and I know it's working like it should. What am I missing? I know this will be a working project but I didn't realize I would run into something the first week that made me scratch my head and say....huh?  I've been reading a lot of posts on here and I'm sure someone knows what I doing wrong.
