Can someone chime in and let me know how to test the female receptacle on the back of my Marathon to see if I have voltage? I hooked up the Jeep yesterday and the signals will not work, the brake lights either. I am not sure how to first test the receptacle with my digital meter. I need to find out if the tow package on the coach is working first before moving to the Jeep.

There is a tow switch in the engine compartment which is switched to on.

I had the Jeep wired for the tow last week. I may have to take it back but wanted to start at the coach first.

Thanks for any help.
