Electric trailer brakes...problems

[ORIGLS6]

Al,
Do you have a small battery on the trailer itself? I had a similar problem earlier this season and simply re-charged the battery on the tongue of the trailer and.... problem solved! I know it's supposed to be the 'fail safe' device, but....

you might try and pull the emergeny cable (pull it out completly) and see if that locks up the brakes if it does then the problem would be from the hitch forward..... also check your power coming out of your plug with a volt meter see what the voltage is coming out of the plugin sounds like it could be low... does your truck have two batterys?

good luck

And something else to check if you're towing with a late model GM product; I had to install a fuse in the box under the hood to power the brake circuit. Is the fuse bad?
(I guess Eddie's suggestion would tell you that though. )

This is true, my new truck had a 'dummy fuse' for the trailer brake circuit - even though my truck has all of the trailering options; hitch, 7 prong, 5th wheel bulkhead on back of cab, and two big batteries, ... but no fuse

Yeah, and their 'instruction sheet' leaves a little to be desired. It tells you to install the fuse in 'this location', but doesn't tell you where THAT fuse block is. The pigtail for the brake controller plugs in under the dash so I stood on my head under the dash looking for this certain lug for the fuse as well, only to discover it was under the hood.

Oh well, everything works for now!
