How did you set it up ?
To chk start with the power flow, find out if there is 12v flowing from the red wire to ground.
Then 2) probe both the 12v red wire and the ground black wire to see if the connection at the ground is good or bad.
If #2 gives you no or an intermittent reading you will know your ground is bad.
If your ground is bad, run a new wire back to the battery or a common grounding point near the battery.
