Hey Guys and Kelly, So tonight as I'm heading down to sunset point I noticed when I turn on my lights (after the car has warmed up, and the gauge is reading in the middle) the temperture gauges goes up a fair amount. I'd say the jump was 1/16 inch. I know my original si batteries are probally shot and I guess this is proof, right?
Can't wait to take that rats nest apart! Can anybody run me through the process? Please.... Cheers, Rick 1988 325is/5 235K |

It may only be a voltage difference due to the extra drain on the charging system...Might be as simple as a ground wire being corroded. Might come in handy on a hot day to cool the car by turning off the lights...(LOL).
Does the same thing happen with other electrical loads? Heater, brake lights etc? Perhaps a volt meter on the battery and monitor as loads are turned on and off. Might be a failing voltage regulator. Bob in Lake Havasu Edited 1 time(s). Last edit at 09/23/2012 09:51PM by Bob in Everett. |

As Bob said, probably a bad ground connection somewhere on the dash or instrument cluster. It acts like putting a resistor in series with everything. Watch out for corroded or loose connections, before pulling apart the SI batteries, not all evil in the world come from them! Very good one! |
