Engine Alarm on a 90SP36

[Michael]

This question is from my friend on the road. He purchased a 1990 SP36
and is on his first trip. The tranny temp gauge keeps going to zero
then back to 215 so we don't trust it. But the real issue is the
Engine Alarm keeps going off when the engine temp hits 185. Can this
be adjusted? Seems pretty low to be sending off an alarm isn't it?
He's running the 300 HP CAT 3208 from Arizona to California with
outside temps at 112 degrees.
