brakes locking

Does adjusting the Hayes do anything? The knob is opposite of what you would expect,

"Turning the handle clockwise will decrease the rate of application of the trailer brakes, while counter clockwise will increase the rate of application."

So if you turned it counter clockwise to put it at its lowest setting, it was actually at it's highest.

If you step on the pedal and the knob moves, then you have brake applied air to it.

Do you have a DC amp meter? You can measure the amperage on your Blue output wire based on the applied brake pedal application.

I have a meter and am in the north Houston (Conroe) area. I'll have some time available late next week or next weekend if you want to trouble shoot it.

Hayes had a bad run. There are several others that had a controller that never worked properly out of the box. Mine let the magic smoke out of itself....the replacement seems to work. If or when this one dies, I'll go with the direct link as well.

Or maybe by then we'll have a different rig with Blue Dot....

If you go with direclink, you will have the trailer brakes adjusted too tight and you will need to replace brake pads in a year. Adjust is to 1 or 2 and see how that works. I like that I'd it is raining I can just tap,the button a couple times and reduce trailer braking.

Electric over hydraulic Glen? If so you need an electrical load so the pump will function correctly. A brake magnet or two most say works, but I had a couple of these:http://www.ebay.com/itm/like/221468420028?lpid=82&chn=ps&ul_noapp=true in parallel with the pump and worked like a charm!

 

I also worked my Hayes over this summer and a few minor adjustments inside and lubed it for a huge difference. I was seeing full application by 15psi so not much adjustment available. I think now it takes 45 psi to get full application.

I think each brake magnet will or should draw 4amp at max input.

10amp reading should show that they work. Have your wife apply a light pressure on the brake pedal- just enough to make the applied pressure move to 10-15 lbs or so,l as you measure with the meter.

Have the gain on the Hayes turned all the way down to lowest point, step on the pedal- measure.

Turn knob 1 turn up in gain- Measure

Turn knob again etc. You should be able to see an increase in output.

6 magnets should be in the 10-16amp range depending on brand and ratings.

 

Can you modulate the controller now? How much applied pressure does it take to max out the lever to the right? My issue was that it only took 15psi or less to max it out wiht the gain on the lightest setting. I also had a noticeable click from the controller when I applied the brakes. This was "Wasting" about half of the little air cylinder's stroke before it touched the lever.....I made a spacer to take this up. The heavier spring made it take 45 psi, so I was able to dial the gain up and actually modulate the trailer brakes on a normal stop.

Ok, got dc amp meter. At full lock reading 6.7 amps at camper on blue brake wire. It goes from - reading up as air is applied or manual enguagement, sliding knob. Sounds like I have brake magnet problems. If so, I likely will upgrade. Also at each wheel reading 1.4ish each wheel at full lock. This is controller on lowest setting
