I think I've figured out what the problem might be ... I was on the phone with schwing earlier and they determined it's either the transmitter inside the handheld remote that's bad, or the Hop-Link inside the CPC Panel (Red box with dipswitches for setting remote signal).

I am going to try my remote on a different pump first, and if I get read-outs then it's likely the Hop Link inside the CPC panel. He said it's usually one or the other thats bad. He believes the Hop Link probably is fine though, since I am getting temperature at the rear panel. And my no-rpm is probably just the Magnetic switch down in front of the PTO box (Fried). I tried to adjust the switch to a dimes thickness on the pickup bolts, but it didn't do anything.

Anyways, just wanted to update everyone what I figured out with the No readout problem I was having.
