What are the chances that ...we were smelling were hot brakes on the truck?
... the bearings in the trailer wheels need to be replaced, so could that hot smell have originated there?
Any ideas/advice is welcome. Thanks---
These are three completely different and very distinct smells, as a few pointed out.
In your 2nd post, you said to reread the first post and then you stated that it was a brake smell and kind of implied that it wasn't the controller.
But in re-reading your first post, you said you smelled:
1. electrical
2. or brakes?
3. or bearings (implying hot grease)?
LOL.
The one thing you didn't state was that you adjusted and tested the controller for the trailer brakes. If your husband turned up the gain while you were driving and you didn't test it properly for lock up, then you were just turning knobs.
LOL^2
Did you bother adjusting and testing the trailer brakes anytime? If they didn't work in the beginning and still don't work, and you don't know, maybe you should find out.
