Are you using a Jordan Controller

If you are using a Jordan Controller I would be interested in a measurement of the output voltage at the controller while plugged into the trailer.

I am having brake problems and am measuring 10.9 volts on the output side of the controller and want to know if this is normal. The input side measure 12.4. Both measurements were taken without the engine running. I would not expect a 1.5 volt drop across the controller but have not other way to check.

Jordan has sold to Camco and they have no knowledge of the working of the unit so I am hoping someone can take a couple of measurements for me.

My trailer is in storage so I can't help you there. Here is a distributor that might be able to help you. Here is the link to their web site.Best Brake Controller

I talked to him and he has been out of stock for close to a year and did not have an answer.

I bought mine from him about 6 years ago. I was hoping he could help. Sorry I don't have the answer at this point. I'm heading down to get my trailer out of storage on April 12th or 13th. I'll watch the thread to see if you get an answer from someone else. If not I'll attempt to get this for you.

Each brake magnet should draw between 2.5 and 3.0 amps when the manual button in pushed in all the way. That would be the led reading.
So for a four wheel system it should read between 10 and 12 amps., and for a six wheel system it should be between 15 and 18 amps.
Mine reads almost 12 on a four wheel setup and brakes fine.

Jordan Ultra

I talked with Mr. Jordan, by the way that is his first name, I cant pronounce his last name, when making up my mind on which controller to buy. We talked about a number of subjects relating to the ultra. One was the very basic circutry of the thing. It seems that there is a pot (three lead rheostat) being operated by the cable that provides input to a high current transistor (amplifier). This amplifier circuit controls the current to the brakes. To loose .6 volts to 1.5 volts is reasonable for this type of series current controlling circuit configuration.
The bad news is that I still don't have a clue what is causing your brake problem.
As per our conversation though I though you amp clamped the individual wires and measured the current. What were the values of current? DC amp clamp required but we talked about that too.
