thank you all for posting, I have a 2000SEL with Gauges gone wild and the wife is terrified. I will be checking the battery tonight. ODd thing is this has happened 3 times in about 8 months very intermittent. So I am thinking a ground somewhere but no idea where to start. I did consider the VSS but the fact that fuel guage jumps as well has me scratching my head and thinking electrical. These jumping guages did not occur on start but while the van was running for 20-30 mins everytime, I am wondering if a voltage drop perhaps caused by alternator may be the case. I will post tomorrow upon checking the cables and the battery. help with where to start on faulty ground would be very much appreciated. My wife is driving me crazy with this and I know computers, not cars, Macs Preferably. |
