Jake, You may have hit on the answer I have been looking for when The Fan Fix in some car wouldn't cut off when everything else was turned off. It was reported maybe 1 out of 20 but it was still there and no one would hunt for the problem. I would really like the EE's out there to chime in on this because it was a problem with only a few cars. We have since solved the problem, but I have said for years there was a voltage or something running around in the car causing the tack problem and relay closer problem. John Hervey -----Original Message----- From:Jake Kamphoefner Subject: [DML] New Battery: WAS Car's use of electricty / alternator & battery question All this talk about the DeLorean electricity made me want to post about my recent battery change. While I didn't really have a problem with my existing battery, I did notice accessories were working slightly harder on the car, and perhaps it didn't crank quite as quickly. Not remembering when the battery was last changed, I looked in my records to find that it was SEVEN years ago! I decided it had served its purpose, and retired it. Other than the obvious benefits (like quicker cranking, slightly brighter lights, etc.), I did pick up one more "fix" from the swap: my tachometer had been acting a little wacky lately when lots of accessories were on, and would often flutter about 1000 RPMs above the actual engine RPM. Knowing that my ground connections were already clean, this was the only other indication I had to suggest a weak battery. I'm happy to report that the new battery solved the wacky tach instantly. I post this message not because anything here is earth-shattering news, but rather as a reminder that a weak electrical system, including the battery, can cause all kinds of weird problems. So how did I get a battery to last for seven years, and it still work? It was a Die Hard Gold, in case anyone is wondering. -But I don't think it had anything to do with the brand name. I attribute it to daily use (even in the winter months), a clean location (in the passenger compartment), and an automatic battery cutoff switch ( called the "Battery Buddy" ). That kept the battery from ever completely draining and certainly prolonged its life.
