Back Up Lights
Thanks, RayVoy - Bulbs, fuses and relay were proven by switching to another position and all checks were positively showing the problem had to be somewhere else. (Sorry I don't have the #'s of fuse or relay positions.) However, your explanation of the routing of the current has repaired the problem. #32 fuse was blown. So, I now have a used, apparently good, Park/Neutral Switch. I also now have a schematic of the exterior lighting and can easily see that the #32 fuse would have been the first thing to check. It's interesting that that fuse was not identified as having anything to do with the back up lights in the owner's manual. So, thank you and I am enjoying the TrailVoy WebSite. :thx
