Question:
The main circuit breaker will not reset?
Answer:
The overcurrent relay (OCR) has been tripped and needs
to be reset before the main breaker can be reset. The
OCR trips when maximum amperage capacity has been
exceeded.
To reset the OCR, simply press down on the reset button
as shown in Figure 82. Reset button is spring loaded. If
the OCR is tripped a slight click will be felt when pushing
down the reset button.

Question:
I replaced the engine temperature sensor but the engine still
shuts down with the high temperature indicator on (why)?
Answer:
The engines have two types of triggers — one is for gauges
(sensor) and one is for engine shutdown (switch). When
replacing, ensure you are replacing the correct part.
Sensors — Provide a resistance reading depending on
temperature.
Switches — Either open or close to ground depending on
temperature.
This rule also applies to the oil pressure sensor and switch.
