Lighting problems

[jackpot]

The intensity of my lights is constantly dimming. Headlight, brake light, reverse light, cluster lighting have this symptom. The instensity of light is''shaking''. My batterie is ok....is it an alternator failure or another mysterious electrical problem ?

Someone have already see that ?

If it is proportionnal to the engine speed, it is the voltage regulator on the alternator.

One trick to fin out parts and price : check at rockauto.com they have an online catalog very complete with photos and good price by the way.

When I back-up the car near a wall and I hit the brake, I can see with the reflection of the brake light the ''shaking intensity''. When I hit the gas for revolutionning the engine rpm, it change nothing. And when I am on the hignway, at constant speed (about 3000rpm), I can see the symptoms in the cluster and more easily in the computer where the exterior temperature appear.

it's the voltage regulator inside the alternator and/or the whole alternator

If the problem is the regulator, it would need to be replaced.
