Dim R/H Headlight


Recommended Posts

I have an 1989 GL SW Turbo. My right headlight is dim on both low and high beam. The bulb is good. I am assuming it is a bad ground or a relay. But I do not know where to find the ground or the relay. Can anyone help me fix the problem?

 

Regards, Aurora

measure the voltage of the incoming wire of both left and right headlights, it should be the same, if its not thats where the dim problem is coming from, it could also be too much resistance in the ground wire, measure the ground wire resistance, put one test lead on the frame and the other in the wire, if the resistances are different you may have a loose ground.
