15Kw generator Starts but no power output

[Darr]

I was having a problem with my MEP804A 15KW generator. The gen set would start fine but when leaving off on the start switch all the gages would disengage and there would be no power output.
I found the KLK 3A (fast blow) fuse behind the control panel was blown, replaced it and gauges all stay on now after switch comes off start to run and we have power.

That fuse is for your DC circuit, which also is what flashes the generator head... so sounds like an easy fix.
