Yes the whole kit was new.
No lights on Ignition Module
- Thread starter cowbelltenors
- Start date
Mr. Wright
Knows some things
I was looking over your posts, and seen that it's your birthday. Happy Birthday
.
I'd start by going back and checking all the plugs. Make sure you didn't bend a pin, or maybe one isn't plugged in all the way.
Why did you change it out in the first place? 99% of the originals ones going out, is caused by a battery that has a short in it, or a voltage regulator spiking.

My original harness was acting up and I pretty much restored the whole bike new pain powder coat rims everything so I wanted a clean harness I rang the wires out no break in the wires. Not really sure but hit the stop button one time it’s leading me to think something cooked in the MHC module because I seen no wire issue or ground issues.

Hi Paul, I'm not familiar with this kit but I read the manual Mr. Wright sent you on the other thread.
Thunder Heart’s Momentary Pushbutton Converter is designed to convert the “momentary” signal of a pushbutton hand control switch to the standard “latching” signal compatible with Thunder Heart’s (MHC) Micro Harness Controller. This device is typically used for the “kill” switch and “high/low beam” functions on a hand control. The turn signals, horn, and start buttons are of the “momentary” type on all hand controls.
This means that the circuit is held after the button is released. I would have expected the circuit to drop after the engine stopped and the key was turned off. Maybe if you disconnected the battery the hold signal would drop. When you turn the key on look for the red light on the Ignition Mod. and don't hit the kill button until you figure out which wires are incorrect.
You could also try just disconnecting the MPC it may not be needed to run the bike. Also just till you figure out the problem.
Info that may help us with this. Does your High/Low beam switch work ? Turn Signals?Horn? I believe you said the starter operates.
My understanding is that after you did the wiring the bike started and ran but after you hit the stop/kill button it shut off ( as it should) but after that it wouldn't start and you troubleshot it to the ignition not getting power. If I have it wrong please explain in detail the sequence of events leading up to the failure.

Correct bike was running I hit the stop button now nothing it the ignition module. I did ring the power wire and ground out they are good. Everything on that pad works blinker,start, and the run button gives me 12v when I push the run button just behind the PCB like it should. I have taken to battery out thinking it also may reset the module with no luck. To not drive my self nuts I ran a jumper off the battery from ground and one from pos and touched the pins on the ignition module and got my red light. What I don’t see is how to test the power coming out of the momentary switch. My switch has 3 wires in one side and 4 on the other. The diagram that was sent to me had 3 in and 2 out so I am sure there has to be something a little different with the one I have. This bike is very sentimental to me as I lost my mom and she loved it but it has taken every ounce of energy to not drag it to the lake and throw it in. I have to keep walking away at this point because I keep doing the same checks that I can and know how to with the same result that don’t make sense.

I think whats happening is the Off/Kill side is staying engaged. Did you try to run with the MPC Disconnected? My diagram shows 6 wires 4 on one side and 2 on the other. I think the module is meant to shut down the engine Not to provide power to the Ignition system. Do you have the diagram or instructions that came with the wire set you put in? What is the name/number of the set.

I didn’t get a diagram with the harness and trying to find one seems to be a big problem

Did you try to run it without the Momentary Pushbutton Converter plugged in . If not do it to help diagnose. look for the ignition light also while the MPC is disconnected.
Who did you buy it from? What name brand and part # is it. If it's the Thunder Heart Performance they have Support you can contact.

I just got home I will try that I bought the kit from big dog not sure who they used to make the harness came with no instruction or wire diagram

OK, Big Dog has support you can get in touch with also this is a Tutorial on installing the harness it may be helpful.

I just watched this tutorial and it will clear up several of your questions. Also you could ask Big Dog if you could talk to this guy. He is probably on site and wildly familiar with issues relating to the install of the new setup.

Yeah I have emailed someone there. So I took the momentary module off and put 12v to the wires until I seen the red light come on the module. My buddy had a momentary module but his had 4 wire in and 4 wires out so maybe that’s why the swap wouldn’t work I guess I will order one and see what happens.

Hopefully Big Dog will help you out. One last question. Did you try to start the bike with the Momentary Module out of the bike?
Paul taylor
Member
Yeah that controls the whole PCB board so it wouldn’t do anything
So it worked before you cleaned up some wiring or did whatever you did? I'm a bit lost on the sequence.
If you hit the run you don't see ignition light what if you hit it again? Still nothing?

Sorry that was a bad explanation. I took the momentary switch off and put a jumper wire off the battery and put 12v to the grey wire and that powered up my ignition module. My only assumption is A) the momentary switch latched when I hit the kill switch and isn’t coming out of that state. B) there is still an issue up stream with the new back bone harness. I have rung the wires out coming down the harness and don’t see anything wrong.

Hopefully when Big Dog gets back to you they can put you in the right direction or send you a diagram. Maybe, as you suggest, the MPC got smoked. If so, the problem will be finding out why so it doesn't happen again with a new MPC.

I agree I never hit the kill switch 1 time I do and all this happens.
