[SEL] OT Electric trailer brakes

[Lew Best]

Thanks Bruce & everyone.  Got them working but about half way to the
inspection place they quit again.  GOTTA be a connection somewhere!  Was
suspicious of maybe the controller but hooked up my other trailer with
electric brakes & it works fine.  Gotta put it on the back burner for a
while; wanted to haul some stuff with it I gotta get moved but will just
have to use one of my other trailers for now unless I get it fixed tonight.
I'm gonna start by soldering all the connections.

Lew, Elden may be onto something.  Do check the wiring well.  10 V is a
little shy, but should work.  I've seen four wheel brake wiring from 16 ga
on up; given a choice I run 12 ga.  Having 10V at the supply to the magnet
doesn't mean much if the ground is bad; check the ground thoroughly.  Here's
what caught me a year ago:  The wiring ran from the street side of the
trailer to the curb side through the axle tube.  Some of the wiring had
abraded the insulation enough to leak voltage to ground, thus causing the
brakes to be very weak.  If your wiring works that way, the easiest thing to
do is just cut it off and run new wires on the outside of the tube and
zip-strip them in place.  You can put them inside a loom if you think you
need to.  Also, use good connectors, not wire nuts.  Look at wwgrainger part
# 4FE24.  I've had some in service for three years on the bottom side of our
fifth wheel covering over 20K miles, without a failure.
