I have a salvaged Klinge generator (a marriage of an Isuzu 32 hp diesel to a Fidelity 15kw generator). Outback inverter rejected power and I found that it was because the voltage had changed. Knowing nothing, I looked around. Nothing. Engine still at 1800 rpms. Herz at 60. Just the volts. Read manual on Fidelity and it suggests bridge rectifiers and diodes. But the damn Klinge is a fixed frame with the goodies jammed in. I can't even get the metal box at the gack of the genset open to look at the guts. Frame's in the way. Anyone know how to 'break into' a Klinge? And, if you do, then what do I do?
