[AT] Brake controllers

[Joe Hazewinkel]

Thanks for the tips.  The strange thing is the lights all work fine, and the controller lights up like it wants to work, but no juice to the breaks.  Seems strange that a ground would effect only one part of the hookup?

Enjoy, Joe

Farmer would tell you to check the grounds.

You can test it by putting a volt meter in the circuit between the power 
supply wire to the
brakes and a chassis ground.  Get someone to engage the brake and see if you 
get a voltage reading.
It should be almost as high as the charge on your battery.  12 + Volts.

Don't have a volt meter?  do the same thing with a 12 V light bulb and see 
if it comes on and how brightly
it burns compared to connecting it directly to your battery.

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
