Generator Pre-Heat

[Ralph L. Fullenwider]

Scott, the pre heat power to the glow plugs goes through a solenoid on the
curb side of the gen set when opened. the coil of the solenoid is activated
by power through contacts of C-1 relay. That is activated by either
pressing the preheat switch on the control box or pressing the stop side of
the stop/start switch. Check the 12 vdc at the solenoid when pressing the
pre heat switch if power then solenoid is bad if no poser then go to the
fuse if fuse is ok then check the connectors on the terminal strip in side
the control box. follow your schematic. I make a copy of my schematic from
the book and mark the copy where I have made checks.

Safe travels,
