Hi guys. I work for a contractor who is a Generac dealer. I was sent to air cooled school, but the generators I'm servicing have been liquid cooled and I'm needing to further my education. When I call Generac when I'm stuck on a generator problem I can't troubleshoot, they tell me they can't help me because I don't have the training. The two day crash course that Generac offers limits the teaching to only the wiring aspect only, but I want to further my education on the mechanics of generators. I was thinking about a small engine repair school, but I'm not sure it's what I need to repair generators. Any help or web links to help me better understand how generators and all their sensors and switches would be highly appreciated. Thanks.
