Looking for advice and/or purchase...my gas gauge & oil pressure gauge suddenly went out at the same time. My friend who is helping me is convinced it's a faulty circuit board. I was surprised to find they were not reproduced specifically for Olds 69 442's. (Aren't they reproduced for say a 69 ChevelleSS?)
Anyhow, my car is a 4 speed console, Am radio, no a/c, w/gauge package.
Any help is greatly appreciated.

 

Try Scott. He may be able to help.

Nice car! Hope you get it sorted out.

 

Circuit boards usually don't just go bad all of a sudden. It takes a major jolt or power surge to break or burn a trace. In almost every case, a board with a broken trace can be repaired. First thing to check is that the large round plug on the back is securely seated.

 

Look up miles71 69 convertible thread he recently documented some repairs to the board on one of his gauges. Loose pins very common on the 68-72 a bodies

It sounds like your friend is just guessing it's the circuit board, unless there are broken pins or visible evidence of bad circuit traces. When multiple systems fail at the same time you need to look for what they have in common. I would check for bad ground connections first before dissecting your gauge units. Here's a page from the assembly manual that shows the grounding straps for the gauge units. You can test for bad grounds by making your own ground wire to bypass the dash straps to a known good grounding point. I hope this helps.

Classic-olds is the greatest! I have followed all the collective wisdom and believe the problem is solved..loose pins, not the cardboard. I have had it repaired by someone on this site. Thanks to all!
