Tow Dolly Tail Light (Right) Stays on

[GIJOHN]

I have hooked-up my tow dolly several times and all parking/turn/Brake lights have worked (7 blade plug). Last night when getting ready for our next trip I noticed that my right trailer light stays on while plugged in. The RV is not running.....any thoughts would be greatly appreciated.

Take a meter and check to see if you have constant power (12VDC) at the tail light pin. If you do find the short on the rv harness. If not find the short on the dolly harness.

Or if a meter is not in your wheelhouse maybe get one of these.
