Trailer abs light woes

I'd find a Dorsey specific shop and take it there versus a place that works on all makes.

 

Is the light on solid with the key on? If not does the light only come on with the brakes applied? When you hold the brake pedal down for over one second does the light go out? If the answers are no, yes, yes everything is working fine. You don’t have power on your center pin of your pigtail, or it’s not making it to the abs system. Therefore the system is getting power from the brake light wire, this is normal and an alternative way for the system to work.

 

When you hold the brakes, does the light go out after 1 second? If so that’s the system self testing. Something is wrong, you shouldn’t be blowing fuses, but it’s not a violation of the light goes out.

 

Sounds like it’s working right to me. Someone might come along and correct me, hopefully they can cite a regulation that proves me wrong. I’d like to learn something.
