Issues with Toad Pigtail

I would start by checking for voltage at the connector. If there is no voltage there, I would check the fuse for the right side of the TV. If the brake and tail lights on the right side are not working then I would check the ground on that light. JMO

Go ahead and check the bulb,this is a prime opportunity for it to have burned out!!!!Murphys Law!!!

We spray the connectors with electronic contact cleaner regularly. Seems to work for us.

Might check the fuse. Mine located in rear compartment. I blew one once.

1. The pins (male side) of the connectors often have a split cut into the pin. After many uses, the two halves of the pins move together and do not put sufficient pressure on the receiving socket. With the power off to the connector, use a small knife to gently pry the two halves of each pin apart very slightly. This has cured a problem on mine several times.

2. Most of the cords have connectors at each end that can be disassembled. I've found some of the connectors loose (screw terminal inside the connector) even on a new cable.

After the above tips, I think you're down to playing detective with the trusty multi-meter.
