Electric Trailer Brakes on a Jayco Trailer Lock Up Frequently

Published 06/04/2015

Question:

The jayco trailer we bought used had its brakes lock up often. The magnets drew from 3.1 amps to 5.0 . Did someone randomly replace with the wrong magnet? Should I replace them all ?

Most trailer brake magnets for 10 and 12 inch brake assemblies should draw 3.2 to 4.0 amps at 12 to 13 volts. On a 7 inch assembly it would be 3.0 to 3.2 amps. Since the magnets you have are drawing up to 5.0 amps there is something not quite right with the magnets and they will likely need to be replaced.

I have included a link to our help article that explains how to test brake magnets and a link to the magnets we carry.
