I'm slowly getting the Fury ready for spring, and as soon as I fix one thing something else pops up!

Today's issue is a non working gas/temp gauge, all the other instruments work fine, all the fuses are new. Is there a voltage regulator or relay that could be bad that would just affect these two gauges? I noticed when I took the dash panel out that there is something that looks like a condenser coming out of that gauge, could that be something I could test?

Besides that all I have to do is install the new heater core that came today, get the after market tach working and adjust the shift linkages and I 'should' be on the road.

thanks!

 

I think you've found the problem. The voltage regulator for the instruments is a small rectangular box, somewhere back, usually on the back of the cluster. It feeds whatever gauges you have except the ammeter. It feeds power to temp, fuel, oil (if you have it) gauges.

 

The amp meter works so does the Speedo but that is cable driven, the clock, temp and fuel gauges are the ones not working, so the dash voltage reguator sounds like the source of the problems.

I took a quick look around the inter-web but couldn't find anything for the 64' 66' yes but nothing prior, any ideas where to get one?

 

The ammeter isn't connected to that VR. On the subject of the ammeter, bein's you have the dash out, take a CAREFUL look at the ammeter. Most Mopar ammeters are put into the dash in such a way that the plastic dash is part of the mechanical structure for the terminals. If the terminals get hot, the plastic gets soft, and the terminals get loose, and then they REALLY get soft........it's a snowball


I'm not absolutely sure, but I'd bet that any of them would work, they just might not mount the same way.

 

Thanks for the info, I just found a complete instrument cluster locally on Kijiji, and the NAPA carries the later regulators, so I should be good to go!

Thanks!

 

Well I changed out the regulator and it had no effect, no clock, no temp no gas gauge also no horn. Going to start checking grounds next!
