Cant Use Brakes or Blinkers or Bike Dies.....

[KaptinAmerika]

No I'm not saying the EHC is bad. I'm just saying that the test box alone really doesn't tell you much. It gives you a down and dirty pass or fail on the EHC but it won't tell you if something else in the system is causing the issue.
Air Ride mode is in parallel with the Headlight mode. Air Ride Mode is activated by pushing the start button prior to pushing the run button when you first turn the key on or after you have started the motor. Doesn't matter if you don't have air ride as it is still part of the EHC's functions.
Have you tested your Right Hand Control board for continuity and shorts as well as for shorts in the right hand control harness back to the EHC?

Curtis I started bike and unhooked right control and hit left blinker and bike died. Repeated other side to eliminate the control boards. I checked all the wiring I could see without takin out of the bars etc and found a few minor chaffed wires and put some liquid tape with no luck. How do I do a continuity test? Thanks

 

[MossBerg590]

Also is the light for horn on ehc supposed to light up when I press the horn or does that mean it is shorting?

 

[KaptinAmerika]

So whenever you use either hand control the bike dies?
If you have the tank off still it is easiest to do it right at the JST connector under the tank.
black wire is ground the remainder are function wires. While Probing to the black probe each individual wire and test the function at the hand control. Continuity when the button is pressed indicates proper operation by the board. If all is good also check for ground between each wire and the chassis.

 

[MossBerg590]

Yes either hand control, front or rear brake as well

Okay so when you use one of these functions and the bike dies have you watched the EHC as this occurs to see if the micro controller is locking up?
If all the LEDs come on and stay on then the micro controller is locking up.

 

[MossBerg590]

Yes I have. When it happens, the horn light and the air compressor light come on for a second until bike dies then the air ride mode comes on and stays lit until I hit the run button.

Does it behave the same way when the motor is not running?

If you have someone close to you with a compatible BD I would pull my EHC and put it in the other bike. If it behaves the same way then you have a micro-controller issue, cannot be fixed, or a software issue. The software issue is possibly repairable by wiping and reloading the software.
If it works without issue then you definitely have a short somewhere in your system that you will need to locate and fix.

The other option is send the EHC to someone who can actually perform all the appropriate testing and repair work to give you a final answer.

I dont know anyone with one unfortunatley. Also bike doesnt always act up...its intermittent and when it does, everything works as it should when the bike is off.( blinkers, horn, all lights etc) Is the horn light on ehc supposed to light up? Mine lights up when I press horn with bike on or off.

 

[KaptinAmerika]

Yes, each function has an LED and will, should, light when activated whether the bike is running or not.

 

[MossBerg590]

Ok well the horn does....nothing else( blinkers, brakes etc lights up on the ehc

 

[KaptinAmerika]

Then you may well have a bad micro-controller or a software glitch.

Which is the EHC right?

 

[KaptinAmerika]

Correct

After 7 pages of trying just old school wire it and be done with it already.... How much pain can you endure???

Money has been real tight with me last few months so I have to build up money on the side for the bike so while I am getting money together I wanted to try and figure out what the problem was so I don't spend money and not fix the problem.

 

[francoblay1]

Have you tried another EHC? if it works then you will know you need a new EHC.

 

[MossBerg590]

No Franco I havent. If it seems like that is the culprit than I will save up to replace it.

I had a 2005 Chopper that would completely die intermittently too. However, unlike yours, mine didn't seem to have anything to do with hitting the brakes or turn signal. Like yours though, is was intermittent, but got progressively worse as time went on. At first the bike would die maybe a few times a year. It finally got to where it would die a couple times a week. For me it would always die shortly after taking off from being stopped.

Had the bike at Arlen Ness for repair, and they said it was the ignition switch. Made sense as when the bike died, it was as if someone had turned the key off...no lights or any sign of voltage to anything. They replaced the switch, and it was OK for a while, but then the bike began the infamous shutting down again. It seemed though that some sort of resettable breaker was involved, as whenever it shutdown, I would just let the bike sit for about 10 minutes, and it would all come back to life and start right up.

I figured something in the EHC was messed up, so I replaced it with the Wireplus. Once I did that, the bike never shut down again.

Problem is, the Wireplus isn't cheap, and it would be a bummer if you shelled out the money for one, only to still have the problem.

Maybe I missed something in reading this thread, but have you tried disconnecting the wires going to the rear lights and seeing if the problem still exists? Doing so would at least eliminate the wiring to the lights as being the problem. Sort of need to go thru the process of elimination.

Do you have a connector under the seat that disconnects the rear lights, if so unplug and see if the bike will still shut off, this would eliminate the wiring and the rear lights as a possible cause from that point. I'm thinking its something in the left handle bar control board but I'm just trying to eliminate the easy stuff before you take the left control apart.

I suggested this 3 months ago but not it. I do follow this but have nothing to share other than a rewire and I would start with the handle bar wiring.

Tyler, its a wonder you haven't blown this up by now
