Iv just had some mods on my car the one electrical are my ecu,turbo timer,gauges now when im going along my headlights dim at random times.Theres no paturn in them doin this can anyone help??

 

How old is the vehicle?

It COULD be a poor earth problem: check earthing points and tightness of battery + and -.

Do BOTH lights dim at the same time? How's your battery? get it, and the alternator checked by an auto electrician.

Check connections to the lights.

Can you make it do it when the car is at rest, but engine running? I'd be inclined to check with a voltmeter what's happening, but it's likely to be a poor connection somewhere.........get it found. Poor connection = overheating = possible fire

Its 2yrs old.I cant meke it do it eitha it just does it every so often??Ill check all the things you said 2night.Both the lights do dim at same time? cheers paul

 

you could have a dodgy voltage regulation module. Cheapest thing would be to replace the alternator.

But is the dimming coming in when you have Fans/heated screen/aircon on??

 

Im sure when the fans cut in they do dim not sure on the heated screen/aircon tho il try tomorrow night.cheers paul

 

The person who had all the stuff iv just had put on my car did also have an earthing kit maybe i need this 2 ??????
