Electric step

Hi Don, thank you for your reply.  Yes I have completed the troubleshooting guides and when testing yellow wire with volt meter at the step / vehicle power harness, there is never any voltage on yellow.  The guide says should have 12v there.  I took the door switch off and reviewed the 2 connectors, took them off and tried bypassing switch and no change. There is also no voltage at that switch at all.. which continues to lead me to that fuse holder under the dash with no power.  Thanks again.

You are using a voltmeter. Multimeter maybe?     So using the continuity test, and making a LONG lead extension you can verify that the fuse under the dash is the source for the yellow door wires that are lacking.

Should that be so, now you know which side of the fuse holder goes to the load. Put one lead into the other side (supply) and you can do a probe around the top contacts on the fuses in the fuse box(es?) and maybe find a poor contact or bad fuse. 

If you a get nowhere with that, then a signal tracer MIGHT help. put the hot into the supply side or the fuse holder under dash, and follow the beeps..

Useful tool. Even tracks copper pipes in drywall.

This is a 2019 coach? I have an antique (2006) so I expect nothing from the factory. But I would hope that a 2 YO coach has some sort of warranty.     At least there is a hope that the guys that built it are still there and you can ask where that underdash fuse sources power. 

Thanks for the good info, I just ordered the tester and will review once received on Tuesday.

Found the issue finally.  I decided to take more black tape off under the step and past the wire harness where I had already replaced butt connectors and found another single wire with butt connector.  It was fully corroded and the wire fell out in my hand once I finished taking black tape off.  After retrimming the wire and installing new connector, the switch worked.  I must say after a month of this issue and now a very sore neck, I am relieved.  Now we just wait for the next thing to fail and require self repair.  https://forum.phoenixusarv.com/Smileys/emotes/2thumbsup.gif
