[AT] OT Electric trailer brakes

[Lew Best]

I've seen lotsa grounding problems for sure but don't think that's the case
here.  The plug uses 2 terminals for hot & ground; 2 wires going to the
brake coils & each coil has 2 wires.  No grounding thru the frame. Seems to
be correct voltage to the coils but I'll put an ammeter on each one & in the
main line checking for 3 amps per coil; 12 amps overall.

I agree with Charlie - I know very little about trailer brakes, but if I 
had a problem like that, the first thing I would go after is the ground 
system. You need a good solid wire connection between the vehicle and 
the trailer (not depending on the ball), and good shiny tight 
connections to the trailer frame, etc. The second thing I would do is 
eliminate any of those "crimp" connectors and solder all connections 
(then cover them with "liquid tape"). Any connections other than solder 
or screw terminals are just problems waiting to happen on outdoor 
machinery. (Don't ask me how I know this.)
