Thanks to everyone who replied to my question about the Leece-Neville 4884JB alternator. This is the original alternator and I bought the coach new so it has not been changed. I ended up speaking with Jim @ AJ Electric and he was very helpful and told me several different test to run prior to ordering a new unit and I am in the process of doing those tests now. He is a very nice fellow and I would recommend this company if you develop electrical problems. I am sorry I did not respond sooner but for some reason I have not been receiving my e-mails correctly.
