Help with Temp, Gas, Oil Alt gauges FREE VIDEO INCLUDED!

So, making some progress here: video here:

My temp, gas or Alt gauges are not working.

I installed a Electronic Solid state Regulator from furygt on Ebay here: Mopar Voltage Regulator - Electronic Solid State with Correct Restoration Look | eBay


NOW I'm getting "movement" from the gas gauge but as you see in the video it, pings all the way up and then goes back down, even though I have a FULL tank of gas.

However Im getting no movement from the Temp gauge. I had a little time yesterday and I used a circuit tester https://www.amazon.com/gp/product/B003UHNMMS/?tag=joeychgo-20

But I saw NO light in the test on the circuit when testing the temp gauge.

My next move was to replace my voltage limiter in the dash with this: Image:Ivr4limiter.JPG - rte

After that, what should be my next test?
