Hey guys, I did my research but could find my answer, here's my problem:
The gauge has three wires
Red - 12V
Black - Ground
Violet - sensor
When I connected the Red to my 12v source and the black to ground the Gauge read RicH???
The guage should not do anything at this point since I didn't hook up the sensor wire yet?
So I ignored it and finished the wiring, and it doesn't work. Just keeps reading rich or nothing at all.
Any one have any ideas ???
