2008 Monaco Holiday Rambler Neptune XL wiring diagram

Hey guys! Im hoping someone can help!!!
I have a customer with a 2008 monaco holiday rambler neptune, my tech is having an issue with the alternator light being on, he has requested a wiring diagram- which i have not been able to locate for the life of me. Does anyone have any suggestions? Or maybe diagrams?

If it is like my 2006 Ambassador it is wired like this:

1. One of the three phase outputs is wired, through a fuse (at the alternator) to a 6 volt relay (in the driver's side electrical bay under the driver.)

2. The relay the turns the light on and off.

Things to check include the fuse, and power at the fuse (AC?) Then check the relay which may be where mine is. My guess is that either that fuse is blown, the relay is bad, or the alternator isn't working properly.

I can dig up a schematic if you want for my coach. Dug and found this one...
