My car starts on the button every time (touch wood)but lately I have noticed that when I switch the car on the head lights are nice and bright but the more things I turn on A/C, radio, electric windows, etc, etc the dimmer the lights get this doesn't change with the bass beat of the music or when I rev the engine but my lights are constantly dim. Anybody know what the problem is?

Cheers Alistair

Ya need a bigger amp!! :D

Seriously though, check the alternator. But if it was knacked, you'd have drained the battery by now. Plus, I take it, if you switch everything back off, the lights get brighter? Confirms alternator's doing something.

Alan :cool:

Would suggest you try the earth mod! Costs next to nothing, and may just fix your problem. It fixed all mine, and the car runs better at idle too!

Note: The Standard Scooby Wiring is wholly inadequate for just about anything. It sounds like you are just drawing a lot of current, and don't have good enough earths to maintain the voltage.
