[AT] Brake controllers

[jtchall at nc.rr.com]

I had the connector on the truck to go "bad". When we plugged it in, it 
would slip backwards and not make good contact. We were intermittently 
getting things to work. For some reason we changed controller at some point 
in time. May have been at the same time.

Can you find the wires coming from the controller? If so check the voltage 
on them while someone else holds the brake pedal down. While doing this have 
them also increase the amount of braking power from the controller, 
shouldn't that increase the voltage to the brakes or am I missing something 
here?

Like others said, check the grounds.

OK,

I know we have discussed this at points in the past, I just don't remember 
all the details, so I'm bringing it up again.  I think my brake controller 
has gone bad.  It just won't engage the trailer brakes at all.  I thought it 
might be on the trailer side, but my neighbor borrowed my trailer, and the 
brakes worked fine for him.

My trailer is a 20-ft gooseneck trailer, with dual tandem Dexter axles under 
it.  Both axles have brakes.  I pull it with an 1997 F-250 diesel.

Any recommendations on a decent brake controller?  The one I have now is a 
Valley brand, and it worked good for the past ten years or so.  I looked at 
the local auto supply place and they had three different models covering a 
wide range of prices.  I just want something that works.  Can you share your 
wisdom with me please?

Enjoy, Joe
