Check to make sure the fuse is not blown.
▪
Check wiring for any nicks, frays, and that you have good clean
connections.
▪
Disconnect the connection to the red/black lead on the back of the
controller.
▪
Use a multi-meter to check voltage on the incoming harness.
•
Red lead to pin on red line, Black lead to pin on black line
– you
must test both leads on the harness, if you ground to a different
location, that will only tell us if there is power or not through the
harness, not if there is ground through the harness.
o
Voltage reading must be between 10-15 volts.
o
Readings outside of this may not allow the control to function.
o
If the readings are negative (Example -12.0), your red and
black wire need to be flipped at the power supply
– the control
has gone into reverse polarity protection mode.
