All the lights on the Seneca might work, but the question is do all connections of the 7 prong outlet work. It happen very often when doing PDI's and people are ready to leave the 7 prong outlet doesn't work proper because of dirt and corrosion. Use contact cleaner spray which in most cases solves the problem. Another helpful tool is to buy a 7 prong checker, then at least you know if the 7 prong outlet is working OK. Is your Jeep wired correctly for Toad purpose? Doing this summer for 4 months PDI's and some speciality jobs in between. Are away from my home base.

ALJO, I have a question. All lights on my TOAD work. All lights on my Seneca Class C work. The question/problem is that when I connect my Jeep to the MH ONLY the headlights and tail lights will work. No brake lights nor turn signals. I have cleaned the connections with the electric parts cleaning spray. A fairly strong neighbor pushed as hard as he coul to make sure it was in all the way.
Any suggestions as to where else to look or try?
