I have a very strange problem. I have two batteries with a standard Perko battery selector switch. The switch was installed two years ago and I haven't had any problems until now. Battery two is connected in the normal fashion: The negative cable goes straight to the engine, and the Positive cable goes to Post 2 of the switch. Nothing else is connected directly to battery 2.
Here is the problem: With the engine off, I turn the battery switch to position 2. The temperature gauge immediately jumps up, like the engine is running. If I turn on any accessory (blower, radio, nav lights), the temp gauge jumps up/right and the high temperature alarm starts sounding.
Everything works. If I start the engine, the alarm goes off and the temperature gauge shows the normal temperature.
With the battery switch in position 1 or Both, everything is fine. I have tried switching the batteries, and the problem still occurs, so the problem definitely seems related to the switch.
Anybody have any ideas? Has anyone seen this before?
