house Posted October 12, 2019 Report Share Posted October 12, 2019 Forgive me if this somewhere else I could not find it. I got my jackalopee the other day, I am installing it so that I have a brake light signal for my brake controller. Not being and electrical engineer it does not appear that there is any overload protection on the circuits in the jackalopee, am I mistaken? Do most people just put overload protection on the 12v line in? I would like to get rid of my current trailer light relay set up if I can, but I hate loosing independent circuit protection of each wire. Am I missing something? thanks nick Quote Link to comment Share on other sites More sharing options...
Nigel Posted October 12, 2019 Report Share Posted October 12, 2019 (edited) I think most of us just use it as is. The factory trailer wiring on the truck should already be fused and you are not drawing any more power than a normal commercial trailer. However I have seen pictures of someone’s truck where he had each circuit fused between the jackalope and the trailer.

Sculptor Posted October 12, 2019 Report Share Posted October 12, 2019 I added a direct battery wire and a 30 amp automatic fuse to the brake controller tabs. Until I did that, my brakes were not working. Quote Link to comment Share on other sites More sharing options...
Moresmoke Posted October 12, 2019 Report Share Posted October 12, 2019 The Jackalopee is primarily just a pass through device. If you are connecting to your trucks original trailer wiring, it should already have overload protection. The only inputs that you would need to provide a fuse/breaker for is the 12v switched or 12v direct connectors in the upper left corner.

Bill B Posted November 2, 2019 Report Share Posted November 2, 2019 Jack is primarily a relay based stop / turn signal combiner. All the electrical fusing / protecting should already exist in the original circuits or by what you add (battery power, etc) with a fuse / cb. Make sure that you use a relay of some sort (or the one in the Jack) for that occasional stop so the trailer doesn't pull down the truck batteries. The control portion needs to be tied into the key on or preferable engine on power line. Quote Link to comment Share on other sites More sharing options...
phoenix2013 Posted November 3, 2019 Report Share Posted November 3, 2019 (edited) All that Jackalopee does is to take what the truck light are doing, rearranges their pathway and puts these into the right wires into the trailer. The few "burnups" that occurred and the Jackalopee was smoked was actually shorts in wiring in the trailer circuitry. You should fuse the line from the truck batteries to the trailer batteries (+12V SWITCHED circuit) with a thermal resetable fuse (30 Amps or so) I spend more time and hours explaining this, therefore, everyone pay attention to these two pictures. This is how the the 12V charging circuit and the brake controller should be wired. The black wire from the batteries should go to the +12V SWITCHED and the blue wire from the brake controller should go the third tab below it, right above where it says +12V AUX. There is a ton of confusion and it's my fault, because I didn't anticipate it and did not bitch out the board layout guy when he marked things. I'm going to have the board redone just for that. See the marking BRK CNTRL right above a tab, that marking actually belongs to the tab to its right, not the tab below. But people see the BRK CNTRL marking above the tab and guess what, it also says BLU right next to it, " I got it, that's where the brake controller goes". Next thing that happens, I get a call. "Brakes on the trailer are all screwed up". I ask, "where is the blue wire from the truck going"? "I plugged it into the tab that says +12V AUX below it". I suggest, "Swap the two blues, see what happen"? "Wow, everything works, thanks so much". I politely terminate the conversation and curse out the board layout guy, AGAIN!!!!!!!!! The board change will take the BRK CNTRL marking and move it to the right of that tab it belongs to and while at it I will also move the +12V DIRECT to the right of that tab. Note also the thin etch going up from the brake controller tab to the LED. The LED "looks" at what is coming in from the controller in the truck and depending on the current and voltage level and will glow dimly or brightly. The marking BRAKE LEVEL belongs to the LED The GND tab next to it is a spare ground, some controllers required it in the past. Also wanted to share with the group the "new look" of the Jackalopees in the future. Edited November 4, 2019 by phoenix2013 Quote Link to comment Share on other sites More sharing options...
phoenix2013 Posted November 12, 2019 Report Share Posted November 12, 2019 "THE FIX" starting with the next batch of the Jackalopee boards, should eliminate the "confusion". Quote Link to comment Share on other sites More sharing options...
phoenix2013 Posted February 2, 2020 Report Share Posted February 2, 2020 (edited) The "fix" implemented Hopefully, should eliminate the confusion of which blue wire goes where. Blue from the truck cable and the blue from the brake controllers. 😯 Edited February 2, 2020 by phoenix2013 Quote Link to comment Share on other sites More sharing options...
GeorgiaHybrid Posted February 4, 2020 Report Share Posted February 4, 2020 Henry, I'm happy to see you put your portrait on the new look of the jackalopee. It might ne photoshopped a little to make you more handsome but a good likeness nonetheless. 😎😁 Quote Link to comment Share on other sites More sharing options...
