Question Charge Line

[Underboss]

It’s relevant though. When I first posted the question, I had a wireless toad light in mind, and I thought perhaps my single wire charge line was not an appropriate application in that setting. I’ve since mentally moved on to a more traditional set up with diodes, etc.

I am going to have to spend some serious time working on perfecting my ESP

Yup...it's VERY relevant..and here's why/how:

If you have a single wire Charge Kit...which a lot of them are...then the ground (from the coach) has to come from somewhere.

The companies "assume" that ground will come from the coach (7-way)-to-toad (6-way) cord, and from the 6-way pin to Toad ground.

HOWEVER...if you happen to run a wireless brakelight system, then there's no need for that cord for those who don't connect the battery kit.

So, the scenario would exist if someone just wanted to stretch a "single hot wire" from coach to toad, and then expect the towbar's metal on metal connection to act as ground. Yes, it should be ok, but to be the "best", then a dedicated positive and negative/ground should be run. And, however you choose to run that is up to you; whether a simple 2-wire (which is DIRT CHEAP), or the overkill 7-way coiled cord (stupid expensive...especially for the RoadMaster nighthawk version I just had to replace for $130!).

Sorry for any confusion I caused trying to keep it short. (no pun intended).
