Ok started to work on my dads (aka xman) 62 polara. Started it up & none of the gauges work except for the alt. gauge. The water & fuel sending units are new. The fuel sending unit has the ground strap. What am I missing ?

constant Voltage regulator. Three prong box on back of cluster maybe.
 
Yeah, what KENTON says, is a voltage 'reducer', down to 5 volts from 12. You NEED to pull it, and test it, to be dang sure it is working. If it's not, you can burn up your gauges!

Other than that, just start with the basics. Battery disconnected, the instrument panel out, so you can get to the backside of it.

Things to check is the panel circuit boards. Mine is a 64, 62 probably shaped different, but same idea. Guessing it's okay, but won't hurt to look. Should be one, or two sets of pin connectors, with wiring blocks attached. Power supply to each gauge, except amp, off those wires. Ammeter is wired direct.
Check for good ground...body to dash, dash to instrument panel base (while it attached).

You can use an ohm meter, to check wiring, and the circuit boards. Sometimes they can get shorted, and will burn out from a section of the circuit.
Power supply wires can be checked with a test light.

Take it slow, and if needed, ask more questions. Some of that stuff can easily be screwed up, not doing it right!
 
See what you are missing. My dash cluster has a clock and two speed wiper switch, so if you don't you won't need those terminals. I have more pics if needed. Your SMS has some good pics also with wireing color codes and wire guage sizes.

This is a cluster from a USA 62 Plymouth. You can see the voltage limiter in my pictures.

I am going to start with a new voltage limiter. Kramer is going to see if they have one if not Tonys parts have them. What is the wire that is screwed below the voltage limiter & has the round cylinder ? I notice that your dash cluster is different from a 62 Plymouth. My dads from his 62 dodge polara doesn't a circuit board
 
I think that's a static suppressor. This cluster is from a 62 Plymouth Fury, Sport Fury, Belvedere, or Savoy (all B bodies made in USA) Canadian Plymouth B bodies had Dodge clusters.
 
I just noticed you said Polara, not Plymouth the only Dodge cluster I have, I can't get to right now.

I took the gauge cluster out today. As in your picture the voltage limiter plugs in to the cluster. The one on mine has wires plugging into the voltage limiter. There is two red wires on the back of the fuel gauge. One of those wires plugs into the voltage limiter.

Maybe you can see the wires better in this pic. (Cluster is upside down)
