dan412 Posted September 19, 2016 Report Share Posted September 19, 2016 I'm having problems with the brake control wiring. The blue wire from the brake controller has power into the terminal on the truck side of jackalope but no power on the trailer side. I double checked all wire connections as per the directions all that is right. what do I check now 2011 Volvo D13 485/1750 Eaton 13 Speed 2016 Montana 3820FK Link to comment Share on other sites More sharing options...
alan0043 Posted September 19, 2016 Report Share Posted September 19, 2016 I'm having problems with the brake control wiring. The blue wire from the brake controller has power into the terminal on the truck side of jackalope but no power on the trailer side. I double checked all wire connections as per the directions all that is right. what do I check now On the Jackalope the terminals have markings on them. Can you tell us what the terminal markings are where your brake wire is going to. What brake controller are you using ? I think this info can help the experts figure out what the problem is.

dan412 Posted September 20, 2016 Author Report Share Posted September 20, 2016 I have a Hayse brake controller and all the wires are in the right place I check for power on the truck side of the jackalope has power there but no power at the trailer side of jackalope. 2011 Volvo D13 485/1750 Eaton 13 Speed 2016 Montana 3820FK Link to comment Share on other sites More sharing options...
SuiteSuccess Posted September 20, 2016 Report Share Posted September 20, 2016 Dan, Best just to contact Henry directly at his website. Could be a bad relay. His site is ethitch.com and their is a phone number listed for help. 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

phoenix2013 Posted September 20, 2016 Report Share Posted September 20, 2016 You should have two blue wires to wire Jackalopee, one a part of the truck 7 wire cable, the other coming from the brake controller. Do not confuse the two. The blue wire from the truck should be inserted into pin 7 (AUX) in the row of seven terminals reserved for the truck. The blue wire from the brake controller should be inserted into the terminal BRK CNTRL, it's in a row of three, at the top is +12V SWITCHED, below that is +12 DIRECT, and below that is BRK CNTR. Note that this terminal is part of a thick etch that goes across the board and ends on the other side of the board (TRAILER side) and a BLU [2] terminal also marked BRK CNTRL. The brake controller signal does not go through any relay, it just takes a "trip" through the board from one side to the other, through that thick etch. Also note a thin etch going up to the BRAKE LEVEL LED which indicates if there is any power coming to the board from the brake controller wire.

SuiteSuccess Posted September 20, 2016 Report Share Posted September 20, 2016 Sorry Henry for the relay mistake. BTW that SWAT takedown in your town wasn't near you was it? 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

phoenix2013 Posted September 20, 2016 Report Share Posted September 20, 2016 I spoke with Dan at length, he had an "expert" install it, now Dan is an expert and is undoing all the expert (?) work. Carl, when was that, I'm pretty plugged into this town? We do have a 20 person SWAT team in our police department, I spoke to them recently at the Police Day exhibit.

Shallow Draft Posted September 20, 2016 Report Share Posted September 20, 2016 Not to hi-jack this thread but: Should the brake light in the Jackalopee light up even if the brake is not applied? Could my brake controller be sending some voltage through even when the brake is not applied? [Max brake controller] The brakes do not seem to drag al all. 2004 Volvo 630, Freedomline, Rear view camera, Max Brake, Jackalopee, 38 ft 4 horse LQ Platinum, 40ft Jayco Talon toy hauler Http:/www.flickr.com/photos/shallow_draft/ Https://flic.kr/p/fqhyAN You are not lost if you don't care where you are!!

GeorgiaHybrid Posted September 20, 2016 Report Share Posted September 20, 2016 Most brake controllers will send a very low current "signal" into the circuit to ensure the trailer is hooked up. That is how it gets the trailer connected/disconnected message. 2017 Kenworth T6802015 DRV 38RSSA Elite Suites2016 Smart Prime Link to comment Share on other sites More sharing options...
phoenix2013 Posted September 20, 2016 Report Share Posted September 20, 2016 Not to hi-jack this thread but: Should the brake light in the Jackalopee light up even if the brake is not applied? Could my brake controller be sending some voltage through even when the brake is not applied? [Max brake controller] The brakes do not seem to drag al all. LED is a diode and as a diode it "avalanches" (conducts) once the forward voltage reaches the threshold voltage. Regular diodes conduct current once the voltage reaches 0.6V. Light Emitting Diodes conduct current (and light up) when voltage reaches 1.7V to 3.3V. Why such a range? Depends on chemistry and color of the LED. Red LEDs will light up at 1.7V, blue ones (at the other end of the color spectrum) at 3.3V. The term avalanche voltage stems from the fact that at that voltage the diodes conduct current but cannot "control themselves" and will try to conduct all the current that is available. Unless you limit the current (with a resistor) the LED (or a regular diode) will light up brilliantly for a moment and then burn up. The current through all the LEDs in the Jackalopee is limited to 20mA each and they light up at 1.7V. Some brake controllers periodically "pulse" the brake circuits to see if there is current flow through the magnetic pucks to ground and that you have brakes (and the trailer is still there). Depending what that pulse is (current and voltage wise), the Jackalopee LED might or might not light. Some controllers also "complain", they don't understand what that 20mA current at 1.7 volts pathway is for? Link to comment Share on other sites More sharing options...

After I talked to you on the phone I went home and figured out that I had the blue wire from the truck in the wrong place. I switched it and now it works all the terminals in one spot confused me.
