Tow vehicle electrcal hookup
I am having a problem with the trailer electrical plug on my 2006 mountain aire 4304. I thought it was a bad pigtail I used when hauling the jeep. Replaced the plug, couldn't get it to work properly,...

Talked with spartan and on my year moho the same fuses that operate coach lights operate trlr lights. Coach is working properly so it is wiring or a connector somewhere. The receptacle looks ok, but I think I will start with replacing it with a new one in case it has funked out. Doubt that is it but a quick and easy try. Then trace the harness as far as I can.
When using a tester, should I hook the power lead to power and then to different contacts while those are turned on, brake, turnsignal, tail lights and so on?
Whoever you talked to at Spartan is wrong. For the past almost 20 years, Motorhome chassis makers (Ford/Workhorse/Roadmaster/Spartan/Freightliner) have ALL separated the Tow plug fuses from the regular chassis lighting fuses. They have done this to prevent a TOW short from taking out the regular motorhome lighting and Brake lighting AND to split the current draw to separate fuses. Running BOTH systems on 1 fuse would require larger fuses(over 30 amp on each circuit) and LARGER gauge wiring to handle that larger load. I NEVER trust the fuse panels schematic. You either use a voltmeter or a 12 volt tester(best and quickest) and check ALL the fuses in the 2 or 3 chassis fuse blocks. Make sure you have the Ignition key ON. Your problem is you have a towable fuse/s blown somewhere. Doug
