Using a test light on the TV connector all pins light up the tester. All lights on the trailer function except the taillights and marker lights. Are the marker lights and running lights in a series setup? All the lights have functioned in the past until I hooked up to the TM the last time. It had been a couple of months since I had taken the TM out camping.
I was trying to use a ohm meter on the trailer connector to see if I had a open circuit on the 3 pin to the running lights and it didn't return a reading at all. I know my ability electrically is handicapping me on this issue. It may be time to head for the RV dealer. Thanks for all the help
