I bench tested mine using a battery charger for power. Be sure to use the right circuit. Continuity tester is a great help. .
Could you give me some details on how to bench test?

I would not use a battery charger. They are usually not filtered nor regulated. If You can test as much as you want depending on how ambitious you are. Take things "separately."
The indicator lights are easy, the high beam, left, right turn, etc, are just one connector pin, one wire, to the light bulb and ground.
All the illumination lamps are one pin and ground
The gauges you need
ground of course
12V to the ignition run pin which supplies the IVR and the gauges power
And then a test resistor to see what the gauges do, one at a time, from the sender pin to ground.
More comin..........
Just follow the pins in the diagram above, starting at the center "key"
The one straight up "F" is the fuel sender.
Going CW, "RT" is right turn indicator lamp
Next one is "blank" and the next one is one end of the "B" Brake indicator lamp
Next one, "O" is for the oil sender
Next one is "B" the other end of the brake indicator lamp. This gets 12V from the key at one end, and the other end goes to ground through the parking brake switch, and the wire hooks up to the brake warning switch, under the hood
Next one "L" (looks like a "V") is your dash illumination lamps
Next one "T" is temp sender
Next one is blank
Last one with the capacitor (condenser) is 12V "run" coming in to power the IVR
LED bulbs ??? You dont happen to have that bulb number handy? I would like to try those. I think my new ones are almost burned out, they seem pretty dim, Lol.
Thanks . If I understand correctly, LEDs are polarity specific. How does that work ? Do you have to install them, and if they don't work change them a half turn ?
Yote
I went with blue LEDs looks cool my dash is a house of colors green. It's what you like is what you go with.But I would definitely do what dragtop said if the dash is out put power to it ,I'll bet you'll have to fix a couple groundsCouple of questions:
With the LEDs and the Rallye dash, did you remove the original mounted blue bulb filters?
As far as color, green seems to be the consensus, I was thinking blue. Does anyone have a preference?
If your using the original sockets for the bulbs the brass tabs don't like to make contactI went with blue LEDs looks cool my dash is a house of colors green.

I just use a 7805 regulator with a heatsink. It's cheap and easy.Does anyone have a link or source to the correct RTE voltage limiter for my car?
also used the battery charger to test. But ended up rewiring the whole car, didn`t want 49 yr old wiring in it. Also bought a limiter off ebay and a new sender. It works , but is slow as molasses getting there ! ???I bench tested mine using a battery charger for power. Be sure to use the right circuit. Continuity tester is a great help. .
Yep, A regulator that can output nothing more than 5.4 volt and 1.5 amp once heated up, puts out a little less than that when stone cold. Does make for very slow needles, especially when running 3 instruments. No more rapid temp changes could extend the life of the gauges, in theory, not proven.also used the battery charger to test.

my fuel gauge is the ony thing that being regulated my the limiter. Don`t get too technical on me here, I`m surprised and thankful that everything works ! lolYep, A regulator that can output nothing more than 5.4 volt and 1.5 amp once heated up, puts out a little less than that when stone cold.

The RTE unit does mimic the mechanical limiter in rapidly heating the gauges/moving the needles at switch on.
I've got my 67 rally panel out now and I am considering a separate 7805 regulator for each of the 3 gauges. Hung up on where to put them, designing and building a home for the little devils. LOL
In that case your fuel gauge is pretty quick compared to mine. You can't imagine how slow my oil gauge needle is. One would think the filter is clogged or something LOL Happy moparingmy fuel gauge is the ony thing that being regulated my the limiter.
