I just bought a 98 EK. I didn't notice one issue with it since I bought it during the day and wasn't that noticable, but now is driving me nuts. The lights keep dimming and brightening by themselves. It's a fast dimming and brightening. Don't matter what light it is either, every single light and anything that lights up.

Can it be the alternator? Should I get the charging sytem checked. Also, it doesn't matter if the running/head lights are on or off. It only happens when the car is running. Also, the speed sensor doesn't work. The speedometer needle starts jumping around by itself, even while not moving. Can this be the same issue or just a bad speed sensor?

 

Any suggestions or anyone ever have a similar problem?

 

My guess is a partial failure of the alternator. Have it tested. In the mean time, make sure your ground cable is tight at the battery, and check the other end where it is bolted to the trans. Corrosion and vibration could have worn the cable down to just a few strands.

great advise, i agree 100 %

 

IF the alternator checks out ok...it sounds like a bad ground issue. Check all your ground wires....make sure you check all of them, not just the ones in the engine bay.
