CUMan Posted May 24, 2004 Share Posted May 24, 2004 I made an interesting observation over the past several weeks. About 2-3 weeks ago, I noticed that my tachometer and speedometer needles did not immediately move when I cranked my car (1993 LS 400). Instead, after about 1-2 miles of driving, they would move to the proper positions. I assumed that I had another gauge problem involving the electronics. (Jim Walker fixed my blacking out dash late last year.) Last week, I changed my headlights to Silverstars. To do this, I had to remove the battery. When I replaced the battery, the car would not start. It would just click. I fiddled around with the connectors and eventually replaced the positive connector when it appeared to be rather loose. The car still would not start. I then decided that there must be some problem with the battery. I checked it with my digital voltmeter, and it read 12.17 volts. I then pulled off the covers and checked each cell with my battery checker. Five read 1/2 charge and one read 1/4 charge. So I headed off to Sam's Club and picked up a new battery. Lo and behold, when I installed the battery and cranked the car, the tachometer and speedometer needles reacted immediately and have worked okay ever since. Apparently a dying battery affects how well the gauges work. It may still have enough power to start the car but not enough voltage for the needles to work properly.

UCF3 Posted May 24, 2004 Share Posted May 24, 2004 <_< Hmmmm. Sounds a little fishy. Is it possible one of the connectors in the back of the Guage Cluster isn't properly seated? Let us know if the problem returns. Quote Link to comment Share on other sites More sharing options...
