Left turn signal activating trailer brakes

[MrSeas]

Have you located the problem? What was the fix?

Have you located the problem? What was the fix?

 

with the freezing temps and then all the rain/ice last couple of weeks, I haven't had time to dig into it yet. We are also preparing to go FT, so trailer is in rehab mode right now. Painting interior, then install all new floors and put back together.

 

I did pick up a new combiner box like is on there, but I'm now thinking I might just get a jackalopee and rewire the whole thing. Still undecided. I probably should just put the new combiner box on there and add a resistor to see if that fixes the problem to verify. Shipping for returning the box is just as much as the box costs.

FYI, when we got the Jackalopee, my bride looked at the instructions and decided it was simple enough for her to tackle. I believe she's right. Crazy easy and high quality.

Did you get this sorted out?

i don't have a jakalopee so this might not help.

My left turn signal also activated the trailer brakes -quite annoying.

So we went right to the fuse panel on the dash - wire 72 I think. now the direct link lights up when brakes applied (as before) but  no more stray signals.

I have a jacalopee sitting in the cab waiting patiently. Finishing up the house first. Few more lights to hang, trim, etc. Then will start on the truck.

Update: 6/27

restate problem: left turn signal intermittently activating trailer brakes. Always shows 0.5 at every blink and sometimes 5.0 signal at every blink, left turn signal only. Brake pedal always shows 6.0, and right turn signal shows 0.0    . 

Combiner box at back end of deck. A little corrosion. Replaced combiner box, still problem.

last weekend was a doozy, but made lots of progress. 

1. Pulled 35 feet of wire from back end to jackalopee

2. Mounted jackalopee and I decided to use terminal strips to completely eliminate and isolate wires in my screwed up harness. 

3. Ran new wire from truck plug to jackalopee, and new plug  

4. Tested without trailer by watching jackalopee board:  left turn led lights up, right turn led lights up, brake pedal led lights up, marker lights led lights up

5. The only not completely new wire in the entire setup is the blue wire from the brake controller. (Teconsha) I cut the wire heading to the combiner box under the sleeper and brought it into the jackalopee. 

6. So had generator serviced (throwing a code) and was finishing up wiring cleanup, zip tying, etc. , while waiting. 

7. Got in truck and check all leds for proper light up when each function activated as stated above. 

8. Never looked at the controller.

9. Driving back to the coach at night, flashing light caught my eye when changing lanes. (Left signal on) and it is reading 5.0. Sometimes 0.5. Crap.

10. So since everything is all new EXCEPT for the one blue brake control wire, I guess that is next. I traced wire from controller all the way to Jackalopee and no breaks or cuts. 

11. Either there is a break or cut that I missed or the controller is bad on the left turn signal? Can't really think of anything else that could be wrong in the setup. 

12. So do I spend more time pulling a single new wire or get a new controller? (Hayes, teconsha?)

And lastly, I cannot find a reverse light input except at the back of the deck in the combiner box. So I guess that means pulling a wire from end of long deck all the way forward to the jack. 

BTW, first thing Saturday morning, I started to take the combiner box off after I pulled the new wire for the trailer. Halfway through, I finally realized all my deck lights and rear lights were pulled off the combiner box and not just the trailer connection. Almost messed up in a big way. Carefully put it all back together and just took off the trailer plug part. 

Thoughts appreciated. 

Thanks,

Shannon

this thread must have the plague. No one is responding! I went ahead and ordered a hayes controller today since I need to be on the road next week and this weekend is the chance to fix it. I hope this does it.

Now where to order a johnson bar? My steering wheel is missing it.

You've had lots of responses, given the length of time this has drug out. Intermittent problems are a bear to track down, so keep plugging away. Given the Tijuana Special conversion that truck has received, it's kind of amazing it's still moving down the road. No 2 ways about it, there's an intermittent short in the wiring, somewhere. Good luck.

Makes me glad I'm using Bludot system. No more electric wires to brakes.

That will probably be next step if the hayes controller doesn't work. But big trip coming up, so want it to work.

The Hayes will work, and work well. I've never heard of a real issue with them.....

[GlennWest]

I'm unsure about the Hayes. That is what I have on my truck. My brakes were locking up and couldn't adjust out. Never happened with dually.  I thought I would find problem when I put the disk brakes on. The electric brakes all appear in great shape, practically new. I may have a faulty one.

[Alie&Jim's Carrilite]

The Hayes units work nicely when they work.  My first one seemed to be hit and miss and eventually the magic smoke came out.  The current one works perfect.  Hayes and E-Trailer indirectly told me that they had an issue with a batch of controllers.  If or when we move to a new RV with Disc brakes, I'll either go Direct link or BluDot if the bank allows.....

BluDot is way better than DL. It does have some downsides, but not in its performance - only in potential resale and other trucks towing your trailer. Not an issue with a tow truck, but it would be with other friends towing it.

Update 7/13/17:

2,192 miles from Cornersville, TN to Delacour, Alberta, Canada. NO LEFT TURN SIGNAL ACTIVATING BRAKES!!

So I replaced every single wire in the system except for the blue wire from the techonsha to the jackalopee, still had the issue. So I replaced with a Hayes unit and took the techonsha out of the equation and voila, magic. 

Now I just need to pull reverse light wire from end of bed to the jackalopee to get reverse lights on the trailer back working. 

Thanks for all the help.
