Dash lights

Only some of my dash lights are working. I checked all the sockets and bulbs, they're all good. It's a new circuit board (72 SS gauges), no cuts or breaks.

Do all of the bulbs work off the same ground?

Is there another reason that some bulbs will light and others won't?

Re: Dash lights

You checked the dashboard light fuse?

Re: Dash lights

Yes, the fuse is good. And unless I've missed something (a possibility), it would be either all or none if the fuse was an issue, correct?

Re: Dash lights

I'd be sure easy pod has a good ground, try running a new ground wire from each of the pods

Re: Dash lights

What I have found is that when using a new printed circuit board you must bend the tabs out slightly on the bulb sockets, so that they put more pressure on the printed circuit board. You must also be sure that the small screws that go through the printed are tight enough to make good contact with the board. Sometimes I even have to add a small star washer to get a good contact. Use a continuity tester to test to be sure you have a ground from screw to screw on the back of the cluster. Have the car battery disconnected when doing this, or you could smoke the PCB. Grounds are a common problem for these clusters having electrical problems.
