can anyone help me with a picture of a 71 charger rallye dash, including the wiring, from the rear side ? possibly a pic or two of the dash cluster and wiring from the FSM ? trying to help a friend diagnose why his oil pressure and gas gauge [and more than likely temperature gauge] doesn't work since he removed and re-installed his cluster. i am doing this from afar, in other words, i'm not able to go there to inspect this in person, and he is not sure he plugged in a couple connections in possibly the wrong place[es]. [is this even possible ?] i'm guessing a bad ground or two, but he thinks he may have a couple wires mixed up. [?] everything worked perfectly before he removed the cluster to re-position the turn signal lens. i tried the google, but got everything except what i wanted ! thanks in advance guys !

Here are some pics. It is hard to see but right centered between the 4 small gauges is the volt limiter that runs those 3 gauges. It pulsated 5 volts to those gauge. Amp gauge gets a straight 12 volts. Chances are it is either bad or not connected right.

PERFECT, PERFECT, PERFECT ! that's exactly what i needed to see, the connections, plus the voltage reducer can. my wife had a 74 charger with a rallye dash 35yrs ago, but i can't remember anything about what the dash looked like on the back side. [i'm guessing it was similar] anyway, i will bet money his problem is a loose/bad ground, OR a bad connection [possibly no connection] to the voltage reducer. now that i know what the reducer looks like, and where it is located, i can have him look at those connections. is it possible to damage the reducer by pulling too hard on the connections during removal ? what happens if the 12v feed is hooked to the wrong tab ? or is that not able to be done ? regardless of the outcome of this venture, you guys ROCK !!!! THANK YOU !!!

This might help as well as Moparmarks. From a '71 RR but don't think that is a difference things just change if is the basic rallye cluster OR if the cluster is with tach/clock, not with years, but still with the different gauges setup, the wiring AND the VL hook up is the same, just feeding diff gauges locations

what is the correct way to test the voltage limiter ? apply 12v and look for a pulsed 5v output ? also, what does the choke/condenser/whatever it's called do ? dampen the 12v input ?

Yes check for a 5 volt pulse. They can malfunction sending 12 volts to the gauges which will burn out the gauges. I just replaced both the VL and gauges on my friends 70 Cuda. They can also just stop working altogether. The condenser stores a charge for the gauges.

You'll never will be able to sense 5 volts, not even pulse, because the pulses are really 12 volts. But the averaging of the pulse going in and out will make 5 volts.
Each VL got its own pulse rate.Is hard to find one equal to the other. You can just test it with a test light or analog multimeter. A digital multimeter will get an erradict reading due the sampling rate for the reading non matching the VL pulses. Althought if you get 0 or fixed 12 VOLTS still on a digital multimeter its damaged on either of those stages. A test light or analog multimeter is more trustable thought. That will tell you is good or bad, but no if the voltage is correct. You will need special testing tools for that, like an osciloscopy
and absence of ground on VL will feed full 12 volts and burn the gauges, so is MANDATORY get the VL correctly grounded
The condenser, PER PN DESCRIPTION its a noise suppressor, but it could work as a buffer power? Actually the VL can work without the condenser and I have seen several cluster without it
