Hi,
I have a 1992 Isuzu NPR chassis in my safari trek motorhome. It has 113,000 miles and is in great condition and worked great up until just after I started it and pulled it out of storage to work on it this winter. First off, I replaced the charge relay and alternator together and it worked - for maybe 15 minutes. Before I throw more time/money at this I would like to get some input as to what to do or look at/test. There is no output from the alternator, batteries do not charge. I've traced wires to verify nothing is incorrect and to the best of my knowledge that is the case. Originally when this showed up, I looked at the alternator and saw that the terminal was ripped/loose so that could cause some problems. However I do not know where to look next.
Thanks for any suggestions!
MIKE
Edit: It is the 3.9 diesel, 4BD2T I believe.
