I bought a new-in-box CHT gauge from e-bay and installed it per the instructions. It does not appear to work. Does anyone know how I might go about troubleshooting it? I have the thermocoupler thing under plug #3 and the wires running to the gauge correctly. The gauge does not "wake up" and move to the 100 C mark when I turn the key on like the other ones, but I have no idea whether it should or not.
I know it is hooked up right and have triple-checked all of the connections etc. This thing is pissing me off!
The only thing I can think of that is out of the ordinary is that when I was pulling the wires through the firewall the ground wire must have caught the lip of the hole and the insulation was peeled back on a very small section. I wrapped it in electrical tape, so it should be fine.
Thanks in advance for any advice. Sure does look purty in the console though!
