Temp and Fuel gauges trouble

I am having trouble with my Temp and Fuel Gauges on my 71 Dart. The gauges are from a a duster or later model dart and everything was working, I took them out to clean them and when I reinstalled them the temp and fuel gauge no longer work. I check the continuity of the wiring harness and everything checks out. I as well checked the gauges when I had them out of the cluster and they checked out too. The only thing I can find that they share in common is the voltage regulator and a condenser seen it the attached pic. I have replace the voltage regulator and still no luck. Does anyone have any suggestions on how to check the condenser pictured or a part number or info on this condenser. It is the only thing these two gauges share in common that I haven't checked or replaced yet. Trying to get these gauges to work again is driving me crazy. I am hoping someone has some suggestions or info that can help.
