.When a circuit breaker opens, it usually indicates a more seri- ous problem exists. Contact Factory Authorized Service Agent.

1 Circuit Breaker CB12

CB12 protects the 115 volt ac out- put to Remote 14 receptacle RC5. If CB12 opens, 115 volt ac output to RC5 stops.

2 Circuit Breaker CB11

CB11 protects the 24 volt ac output to Remote 14 receptacle RC5. If CB11 opens, 24 volt ac output to RC5 stops.

Press button to reset breaker.

5Circuit Breaker CB9

6Circuit Breaker CB10

CB7 protects the engine glow plug from overload. If CB7 opens, the glow plug does not work and engine may not start in cold weather. Check continuity and connections of engine glow plug.

CB8 protects the engine wiring sys- tem from overload. If CB8 opens, the engine will not crank. Check battery, starter, and engine control switch.

CB9 protects the engine throttle so- lenoid from overload. If CB9 opens, the engine will not run at idle speed. Check throttle solenoid TS1 for ob- structions.

CB10 protects the engine fuel sole- noid from overload. If CB10 opens, the engine cranks but does not start. Check fuel solenoid FS1 for obstructions.
