ok so basically. 1 headlight works properly and now 1 does not,
it's like it doesn't receive enough power i really dont know. it's just dim. i pulled off the h4 ballast and changed bulbs and the same thing happens.
please help!!!

 

check the connector...

FC connectors are not that great, mine are already burnt to a crisp! (due to water and corrosion)

 

anything i can do with the connecter other than try to replace it?

 

if t looks srewed, then replace it

 

what ballast?

H4 bulbs are 12 volt and do not require a ballast.

The stock headlight bulbs are H6054 bulbs, and also do not require a ballast.

Dim bulbs are the sign of a damaged or corroded connector or a bad ground. Have you tried conductive grease in the connector's tabs? Did you check the ground?

 

I nhave had to fix both headlights on a pal's ride; the connectors looked a little warped from heat and very corroded. We switched the entire assemblies to a custom non pop up with bimmer hids and a ballast.

 

the ground on is bottom slot is it not is there another ground somewhere?, i havent tried the grease yet,
