Temp Alarm

[Scalpel]

259B3 CTL. Idiot light flashes and beeps when using machine at moderately high idle. I flushed the cooling system & replaced the thermostat. Problem persisted, so I replaced the temp sensor in the thermostat housing, pulled the belts and checked the water pump - no slop, turns easy. Next step is to hit the thermostat housing with an infrared thermometer when it's alarming. Dealer says the thermostat opens at 180 degrees, but can't tell me at what temp the idiot light starts flashing/beeping. Anybody know what the alarm temp is? Anything I'm overlooking? Thanks

Since it happens when you throttle up I would guess it is the wire shorting out Also some had two temp sensors, The other one is on back it head

Check your overflow bottle for overfull/compression too, Just in case....
