hi paul,
i am trying to think how the dash ac (i assume with the coach engine running) would have any impact on the generator temp. the temp sender on my 02 genny is right near the thermostat and from there it goes i believe straight to the gauge.
you are for sure right that the temp couldnt go up and down that fast.
if it has the same genny engine as mine, it is a kubota 2003turbo. i looked in the manual and there doesnt appear to be a high temp shutoff switch in it.
the digital gauge for my genny temp is over the drivers head. so it is either the sender, the gauge or a connection.
btw, my genny temp gauge reads lower than actual temp all the time. i will be figuring out what is wrong with mine too.
