I change a few burnt bulbs, in the cluster, in my SC. I put it back in, and the backlighting isnt working at all!

The needles are fine, turn signal and brights indicator are fine, but NO backlighting for the gauges.

What could I have done? If I have the polarity backwards on one bulb, would it cause this?

 

Dang, I thought someone would know. I dont guess I could of posted this in the sc300 section?

 

May be something is not pluged in correctly. Did you check dimer setting.
Where did you get parts?

 

I only changed three bulbs. I got them from an electronics supply place. I plugged in the dimmer, and adjusted it back and forth. It adjusted the needle brightness, but the backlighting is out.

 

Backlight is designed into the three top ribbon cables.

 

So I should pull it out and make sure theyre connected properly? I sure hope its as easy as that.

 

yes that the first step to take.

 

did you fix it?

 

Not yet. Ill give an update.
