Brake Controller Showing Short in the System

I think John that you will find that you have an intermittent short being caused by a brake wire inside a wheel hub that has broken loose form it's metal clamp and the wire has rubbed thru the insulation on the inner hub of a wheel...

I had 2 shorts like this with 2 different trailers and in both cases, it was exactly that... I know you don't want to pull the hubs but I would be willing to bet that is where the problem lies...

Pulling the hubs isn't that bad and you don't have repack the bearings again if your careful with the removal and re-installation of the hubs...

I know you don't want to hear that, but my money is on a brake wire short inside a hub :( :R

I suspect that your brake controller has now stopped working because the controller now is "fried" because of the short... I also experienced that on the first failure as previously mentioned...

Thanks Les. I suspect you're right, but I hope I've not damaged one (or both) of my controllers in the process.

I don't mind so much pulling the hubs off... but would like to narrow my search to one or two instead of pulling each one to find the last had the short.

If I have to, this weekend I'll pull each hub for inspection... the weatherman is calling for mostly sunny skies with temps in the mid to upper 60's. Sounds like a good weekend to work on the camper. ;)

Happy Camping!
John.
