Have been hovering on this thread. You guys are definately working it through the ringer. I agree with the troubleshooting methods taken by all. What a GREAT FORUM!

Voltage and Continuity are two different things.. you need to isolate the starter relay wire and check it's continuity or Load test the wire using a "full sized headlamp" From the EHC connector to starter.
Can you get it to crank by using a 12-14gage jumper wire from the battery to the starter "green" wire connector?
I am going to suggest the jumper wire also. That will rule out the starter soleniod and the starter. That low voltage suggest to me that you may have a something going to ground pulling voltage off. Or EHC faulty. By jumping from the battery to the green wire connection will zero in on this. hope this helps.

Jumper wire test

OK, I tried a three hand operation with two hands last night and tried it again just now with proper connections on the jumper wire and the bike fired right up when I jumpered from the solenoid to the battery so it's definitely not the starter. I still think the low 4.7V coming from the EHC is the problem......:bang:

Got exactly the same problem. compression release same clicking, only right front blinker wont flash. This is the third module, everytime i have problems, always comes back to the MODULE!!! Try wiresplus.com
Dave, are you saying you have replaced the EHC twice now? :eek:

The last thing left that could possibly be causing a problem is the short green wire from the module to the solenoid. The wire is shrink wrapped over the green plastic insulation and it's inside the mesh wiring harness from the EHC plug to where it exits to the solenoid so I don't see how it could be chaffed or grounded where it's routed.

I'm may isolate the plug from the EHC and check for ground to rule out the last thing prior to concluding it's the EHC for sure. Any thoughts?

Excellent idea. If you remove the connector from the EHC and then teat the green wire to ground should be infinity....

Unless of course something else is grounding somewhere and causing the EHC to put out low voltage..just a thought may be blowing smoke out my butt...

I just realized that my front left light is not blinking when I press the turn signal button. The light works when in normal running mode and the rear left light blinks but not the front left turn signal. Damn gremlin is doing a good job of hiding. :rant: Now I get to trace that circuit out to see if it's causing a low voltage. Thanks for the tip Erl (Unless of course something else is grounding somewhere and causing the EHC to put out low voltage). :2thumbs:

You might want to pull that tank and make sure you don't have a wire shorting against the frame under there. I realize you had the tank off before for painting but did you take the wire ties off and inspect each wire?

Brew, no I haven't inspected the wiring under the tank since re-assembly but that's next on the agenda now. :2thumbs:

I wish I had more money.
I have to agree. This is a good one. Rrruff and Erl the Pearl are the men. These are the ones that teach me the most. Process of elimination is a beautiful thing if you know what to eliminate. I know it's not yet fixed but good dang job guys. And for keeping you head in the game and not giving in.

Now you are on the right track.:2thumbs: If you don't know what is then rule out what it isn't. Now check all your power wire and see if any are going to ground. If all is good then ehc or circuit board in the right hand control.

Well, I pulled the gas tank and there's no visible signs of a pinched wire. :bang: I Di-greased the connectors while I have access to them. I also popped the left side hand controls to take a look but everything was clean and dry and the circuit board looked like new.

So....can't start with the push button but I can jump start with a jumper wire to the solenoid, left front turn signal doesn't blink but does burn solid, all other lights burn and blink and no signs of a grounded wire. :angry:

I'm running out of things to check. Anyone have any more ideas, or a spare EHC for a carb bike I can swap out to make one of the last tests I plan to do before calling Wire Plus for a replacement module? :confused:

Are you sure everything in the headlight is wired, plugged or solder good? Maybe the intermittent problem was in the headlight and something you did made to a permanent issue. It is always good to go over the last thing you did carefully.

Nuke, the only reason I messed with the headlight was to rule the HID out. Your point about making an intermittent problem a permanent one is well taken. I'll probably put the HID back in since that's not what the problem was and when I do I'll inspect everything again thoroughly.

Thanks for the feedback.

The high beam, low beam, turn signals, starter solenoid, all are connected internally for power inside the EHC (Bus 1 & 2).

If you still have the tank off disconnect the turn signal connectors and compare the wires- violet (left) and brown (right) to ground on both sides of the connector (turn signal side and EHC side). You could do this by putting your meter across each wire (violet, brown) to the black wire in the connector or connect your meter to the battery ground or frame with a clip. Don't forget to check the black wire to ground should be zero ohms. Hopefully you'll see something different.

Erl, I'll be putting the tank back on this afternoon so I'll check the two turn signal wires before I do.

Thanks :cheers:

With the turn signal connector unplugged under the tank, looking back at the EHC, I have balanced readings on the violet and brown wires, solid grounds on both blacks, and 12.5V on both reds. Looking back toward the turn signal side, no grounds, just good clean wires.

One last look at the headlight for possible grounded wires but the light itself is operating fine.

Curdog ,

Did you find out what the issue was yet ? my bike is doing the same thing but i just changed out the battery ...mine will work sometimes and sometimes is wont ..
