I have a 2002 Monaco Windsor with the ISC350 and have a warning light on. The book says it is just for fluids. Well I have checked everything and nothing is low. Replaced fuel filters too. With the warning light on it is weak on power. I'm looking at replacing the surge suppressor 3944110. I have had someone else have similar issues and that was the culprit.
Anything else it could be?
Any help is awesome.
Thanks,
Dave
