MEP-831A Engine Temp High Always on

[SSingh]

I have a MEP-831A which i cannot seem to diagnose why the engine temp high indicator remains on all the time. On a cold motor, it is still on and the indicator will not clear.

But the set continues to run?

It does continue to run, i have to manual shut off the engine. The magnetic shut off does not close itself.

No suggestions?

This could be because the over temp switch is bad. It could be because the wire Harnes has problems. It could be because the fault indicator is bad. Have you read the TM's for the testing of these items?

Have you adjusted the magnetic shut off? Or anything to do with the throttle system? Have you ever seen the set run right?
