New alternator now Alt charge light

[dobrien]

Here is an odd one.

Alternator went bad had it rebuilt.. Put new Alternator in and it ran great just about 14 amps on the gauge.

20 hours later started RV up and now the Alt check light is on and a strange burning wire smell is in cockpit.. I check 12V fuse panel at left front tire and it had a strong burning wire smell and I can't figure this out.

On the alternator there is an " terminal " and and " S " terminal. both wires leading to Alternator are white and both go into same loom so no idea which goes where.. only difference in wire is that one is thicker then the other... Does thin one go on the " I" and thicker one on " S"

Please help.

These appear to indicated that the thinner wire is a sense wire, and attaches to the S terminal.

If you attached it the other way, then I suspect the alternator would put out too much current across the sense wire and burn it up. You may have to rewire a new sense wire, or looks like you could even just connect the sense terminal to the positive output. Hope if it burnt, it didn't burn any other wires that are in the same wire wrap. Read the article.


And I assume when you wrote 14 amps, you really meant 14 volts....
