Have a problem where the temp indicator lamp on the console FLASHES continuously while the key is on (cold motor). When the key is first turned on, all indicator lamps momentarily light, as normal, then all extinguish except the Temp Lamp. Originally thought the problem may be related to the temp sensors. Found the temp sensors on the heads, disconected, light still on. Shorted the leads at the sensors, overheat alarm horn functions normally. Any suggestions as to what may be causing the temp lamp to flash?
