Help!!! Seriously please help!

[BCombs]

I have an 05 Pitbull. Needed a new EHC and managed to find one. Put it on and was eagerly anticipating to hear her start up. No luck. On the EHC the power light is on and the control light flashes green. When I attempt to start the air ride mode light comes on for a brief time. No other physical signs of anything...no clicks, no dimming of the headlight, nothing. All lights illuminate strong but when the start button is pushed no signs any juice is being pulled from anywhere. Any help, suggestions , any help would be appreciated. Please keep in mind I am not handy at all but I'm willing to try with some assistance. Thanks in advance.

Check the run button to make sure it is completing the start circuit. Might wiggle it a little with your thumb or check to see if the red "power" light is lit on the ignition module.

 

[BCombs]

Thx Blacktopper. I'll give it a shot.

 

[BCombs]

Hey blacktopper. I'm not seeing where there is a light on the ignition module. Where is the damn thing?

 

[BCombs]

Found where the red light is...not on! Could this be the issue? Now what?

 

[blacktopper]

Yes. Check the right pcb run switch

 

[BCombs]

K. Sorry I'm a little slow. What's the pub switch?

 

[Sven]

Is the EHC new or bought used?
How about that breaker switch under the seat? Look up under there on either side, or might be right side?

 

[BCombs]

Oops Blacktopper I meant what is a pcb switch. And Sven the EHC is used but tested good. What is a breaker switc

 

[BCombs]

I guess I'm wondering what would cause no light on the ignition module?

 

[blacktopper]

Check the run switch on the right hand forward control. If that switch isn't working the bike will not start and the ignition module will not power up

 

[BCombs]

K. I will do that. Exactly how do I check that. Sorry for the goofy questions. I just don't know. I'm not mechanically educated at all.

 

[blacktopper]

Push the run button and see if you can feel it click. If you can't feel anything it probably isn't working. You might try pushing several times at different levels of intensity and watch for the power light to come on on the ignition module. If it ever does I think it should start.

 

[BCombs]

Thx blacktopper. I will do that. I really appreciate your help. I'll keep you updated. Thanks again.

Take the right hand control pcb housing off. Disconnect the header connector at the pcb. Take a paper clip and bend it into a horse shoe shape. With the key on take the paper clip and momentarily jumper from the black wire to the red wire in the header connector. That should enable the ignition circuit and send 12VDC to the ignition module, turning on the red LED. If it does then you either have a loose connection at the pcb mating with the header connector, the rubber switch for run is worn on the inside to much to "click" the dome switch on the pcb or a bad trace in the circuit board itself in the pcb.

If it doesn't engage the ignition circuit when you jump across those two wires then you either have a wiring issue from the red wire back to the EHC or the ignition power output of the EHC does not function. This could be a damaged connector under the tank or even a pulled pin out of a connector under the tank. Look over your harness in the battery tray area as well for wear or damage.

A couple other things to consider is the inputs to the ignition module itself. The three pin connector going to the ignition module (the one with the red wire, green wire and black wire) when you hit the run button see if you are getting 12VDC to the module on that wire. Also check the black wire for continuity to ground.

If you hit the run button and are in fact getting 12VDC to that red wire and you do have continuity to ground on the black wire and the red LED is still not lighting up one last thing to do is take a jumper wire and apply a chassis ground to the ignition module itself. If hitting the run button and applying 12VDC to the ignition module with a good ground input as well as a chassis ground still doesn't engage the red LED then you are left with the only option to replace the ignition module.

Actually got on a roll on that last post. The issue is the lack of run input to the EHC, not output from the EHC. The issue you describe is the EHC is going into "Air Ride" mode since the EHC is not receiving a run input.

 

[BCombs]

Ohmster thank you for the detailed info. I will do this hopefully tonight. I'll let you know what's going on... Thanks again!

Ohmster, thanks for your contribution to this post. It was very enlightening. I'm going to save it as I am sure I will need the information sometime in the future

Ohmmeter...ok brother. I placed the paperclip on the red wire in the pcb header connector. It attempted to turn over. Drew juice from the headlight and then the ignition module led light went off. The EHC now has the ignition led on solid red . Hopefully these are good signs... Waiting on what to do now. Let me know. Thx

 

[BCombs]

I've tried a few more times to start it now on the EHC the ignition light is off but when I hit start the air ride mode comes on again. But at least I know that when I put the paper clip on the red wire the ignition powers on. But when I reconnect the header connector on the pcb and hit start it will click as if an attempt to start ( draws juice from bike headlight dims) and then the ignition module kicks off and the EHC (like I said earlier) light up on the ignition led but now air Ride mode is light up. Please help
