MANUAL STARTER DISCONNECT (TOGGLE SWITCHES)
CIRCUIT PROTECTION:
The engine control system is protected by a 20 amp manual reset circuit breaker located on the engine
as close as possible to the power source. An additional circuit breaker is located at the fuel solenoid (P/N
23041) when this solenoid is used. (This solenoid is not used on models which have a solenoid built into
the injection pump.)
