dim dash lights
Hey folks, all my dash lights light up when the car is running, all of them very dim until I rev the motor, then they all get brighter. None of the lights are "fully on" and everything works fine. Its been like this for quite a while now just wondering if anyone has any ideas?

Sounds like theres a heavy load on the eletrical system.Do you have a stereo system(amps) ?I have the same problem and it has a brand new alternator.And A new refurbished battery.I think Im gonna get rid of the battery and get a optimum red top.I that doesnt hepl I might have to upgrade the alternator.
I would just take it to a shop and have them check ththe charge coming from the alt also get the battery checked.

Yes I do have 2 amps (nothing Huge), 2 sets of fog lights, some extra gauges, new style headlamps, and some pedals that light up. I put the bigger alternator in from the newer models, didn't seem to help. The rheostat knob doesn't do anything for it. now what? thanks for the responses people.

yeah, I guess it is time to change the battery, Its been 5 years. I drive it only 3 times a month(always in the work truck) but it always starts right up. I change the battery and see if that fixes it. Thanks peoples.

'88 300 E
I have the exact problem.
In fact I attribute it to the rough idle at start-up. I haven't checked this yet but I beleive it to be the over voltage protection relay. It's behind the battery. On my 88 300E it's silver with a black top and has a plastic door on the top which protects a 10 amp fuse. If I find anything else I'll let you guys know.
