Power supply check to right side of gauge cluster.

[kaj750]

All of my gauge cluster lights used to work. After having the cluster out, the right side (circuit board) stopped working after one of the "posts" for the wire harness broke off the circuit board, while I was running wires to/from the ammeter. I assumed this was for the power wire, so I "made" a post to test. Connected the harness. No luck. So I then replaced the circuit board with new. I've tried (new) what I *think* are the correct bulbs and sockets (per Classic Industries) with no luck. They do seem to fit a bit loose. I ordered another set from another vendor but am having trouble finding them. Things I've also tried:
New aftermarket headlight switch.
New aftermarket dimmer switch.
Separate wiring to/from ammeter to take some of the stress off of the OEM wiring.

All gauges work and all lights on the left side of the cluster are fine. Is there a way I can temporarily run power to the circuit board side so I can trouble shoot? I'm not sure if it's a mechanical/parts issue or power supply. I SUCK at electrical work so kinda stumbling my way through this. None of the shops in my area will touch any of this.

Thanks, in advance.

Sure you can.
But it sounds like a test light or meter would be helpful.

Lots of questions here.
What are you working on.
Is the cluster still out of the car?
Do you know for sure, that your ‘replacement’ post is making electrical contact with the circuit board? Use an ohm meter to see if you have continuity.
Do you have an electrical diagram of your system so you can determine which post on the circuit board does what?
If your cluster is out of the car, you can run power to it using a battery or power supply but if you’re not sure how to do this, I would get help from someone who knows and learn from them because you could cause more damage that might not be repairable.

‘Separate wiring to/from the ammeter’ brings up a whole different set of questions…..
