Hello,

I need a little advice. I've been working on the instrument cluster/ POD on my 1984 US car. I pulled it about a year ago or so to fix the odometer. Found the typical gear with teeth missing scenario. I replaced the gear and the odometer has worked just fine since then.

I pulled the pod again last weekend to install one of Mr. Champagne's masterpieces and since then the odometer has stopped working. Everything else works. (speedo, etc.) While I had the instrument cluster out last weekend I cleaned the flexible circuit board connectors lightly with a Scotch Brite and snugged up every brass screw and nut on the board. Any ideas???

I'm also working on what I think is a grounding issue. All of the gauges work but the temp gauge jumps up about 1/4" when the parking lights are turned on. Back down when I turn the lights off. Also the voltmeter moves up and down 1/8" or so when the turn signals are on. This is an "old" issue. Any advice on this one?

I've cleaned all of the grounds I can find on the car and the battery is new. (last year) She stays on a battery maintainer whenever it's not being driven.

Thanks in advance!

you probably have disturbed a contact on the pod, to clean the flexible connecters that the harnesses slide onto use a pink eraser only, scotchbrite will damage the wave.
also there should be 3 pins on the rear of the speedo that the wave slides onto and possibly nutted. these are known to cause the speedo to stop, these may need to be recleaned and reseated or soldered(last resort). The gauge moving with the TS blinking sounds normal as it is a on/ off drain

It was a light cleaning with the scotch brite. I was very careful- don't think I damaged anything.

Anyone know specifically which connector/ pin # feeds the circuit? Can I measure a specific voltage or resistance?

Thanks!
