This issue involves THIS car but before I get to that....
...I'm building a 1990 roller 360 for my beater 67 Dart. The car sits most of the time so the dead temperature gauge hasn't been an issue but with a fresh engine going in, I want the gauges to work. I remember the old test where you unplug the temp sending unit wire and ground it while a helper looks at the gauge to see if the needle moves.
In the Dart, I grounded the sending unit wire to the negative terminal on the battery and the gauge didn't respond.
Dead gauge or did I burn out the voltage limiter? The fuel gauge hasn't moved in awhile so maybe the voltage limiter was already dead.
In the interest of testing my diagnostic skills on another car, I went over to Jigsaw, the ratty Charger. Same tactic...I pulled the wire from the temp sending unit and ran a wire from it to the battery negative while Rich watched the panel from inside. No movement. In both cases, the ignition was ON but only for a few seconds, maybe 15 to 20 total for each car.
NOW the Charger has no movement at the oil pressure, fuel or temp gauges. Yeah, the ammeter still works!
All the gauges worked before. I mixed and matched the small assortment of gauges I have to get a complete set that worked.
I have several 72-76 A body instrument panels in the attic along with a few Charger and 72-78 pickup units. Do they all use the same voltage limiter?
I remember hearing that newer designs were made that were more reliable. Do you know where to find those?
Of COURSE I ask this right as a 4 day weekend is within reach when all stores are closed but I'd like to get started on this. It would be great if the limiters from other models are interchangeable.
