c.
On switchboard, check that GENERATOR circuit breaker (Pi or P2) for starting generator is OPEN.
d.
On switchboard, set AMMETER SWITCH to ON.
WARNING
Ear protection must be worn In vWs 4 when generators are operating.
e.On starting SSG, push ENGINE START/STOP SWITCH up and hold until engine starts. Release
switch when engine starts. Engine should start and operate at idling speed.
NOTE
If engine does not start within 30 seconds, release ENGINE START/STOP SWITCH. Wait 2 minutes for
starter motor to cool. Then, try again. Release SWITCH when engine starts. I engine does not start after
three attempts, troubleshoot by following procedures on page 53, Caterpillar Systems Operation Testing
