Should I repair the factory gauges of?

[Stucat]

My gauges on my 69 Charger need help. Rally setup with tic-tok. Should I get them all(6) rebuild? Or are the OER gauges for $900.00 and good ? Or are they NG and only last a few years? I would think it would be more $ to rebuild them as to buying new. Thanks

I bought a couple new ones. JMO Are yours bad?

 

[dadsbee]

Are the gauges actually bad? or just need repaint and redecal

I was in the same boat 4 years ago. I was pulling the clusters every other month. I fix one gauge and another starts playing up. After pulling the cluster for the 10th time, I bought the Dakota Digital cluster and it was the best decision ever.

Seriously guys. All the rallye gauges are, are volt meters in disguise. There is nothing extremely technical with them. They run on a pulsed 5 volts. If your voltage regulator isn't working correctly or sticks they get smoked. Full scale requires 10 ohms of resistance and the empty/ cold / zero oil pressure line requires 74 ohms.

Yep...I used a temperature gauge as an oil pressure gauge for a while

All three are identical gauges, just different labelling..

I think it's fair to say they are more like ohmeters.

Thinking isn't knowing though... i would talk to someone that restores gauges (has to be someone on the forum) and get a price and go from there... i would trust rebuilt originals over replacements, but that's me and i also like to save what i can of original stuffs...

Nope, they're 0 to 5 volt meters. The resistance of the sender is what changes the voltage.

I'd like to agree but I can't. They are measuring a current through a series circuit. A voltmeter measures the voltage of a certain point in a circuit, in parallel.

Gauges have been in storage for about15 Years. Came with a parts car an d extra parts. will need to be refaced for sure

 

[Stucat]

Is there a way i can bench check them. Do they sell a refacing kit? thanks

There’s an online free magazine and it’s through Shaw publishing a while back that showed how to bench test gauges I’ll look later, Bkack Friday shopping with Mrs

Yes, they can be bench tested pretty easily. Some resistors (10, 23, & 73 ohm) or a DYI version of the original C-3826 Miller gauge calibration tool. And yes, decal sets for that Rallye cluster are out there.

I won't do a "Renton" on you and leave my pinky ring in the jewelry box, but it's just a volt meter being manipulated by a rheostat.

BTW OP, no need to go any further than our Members Restoration section to see how it's done.

I think you both have very valid points......you could call them a Giraffe if it helps.

They do have characteristics of both ohm-meters and Volt meters......but that's just my opinion of course.
