I am working on a ford chassis motor home, class A. My problem began by trying to correct the loss of a right turn signal. The left had worked just fine. All bulbs, and fuses checked out fine. I decided to replace the flasher and when I did, I lost the left side as well. Now I do not have any turn signals. Furthermore, I do not have power to the wire harness that the flasher connects to. Can any one help and or, where can I obtain a wire schematic ?. Andy

 

What year motorhome? Might want to recheck all your fuses and relays.

 

Hi Andy,
I have a similar problem, that is I have a '99 Winnibago on a F53 chassis. When I put on a new towing package for towing my 2005 Escape, the signal lights on tow vehicle went shortly afterwards. I checked all fuses and even tried changing the relays that are on the side of the fuse box. Maybe that will help. By the way, where is your flasher located on your MH - the Ford dealer doesn't know. btw I posted here as I could not figure out how to put up a new post :-(. My apologies

 

...that is why I love the old school way of using hand signals.

 

i had that happen on my truck and found it was a secondary ground that ran the length of harness, but double check your fuses and any visable grounds for good contact. hope this helps.
