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

No not necessarily.

I think you are down to either the EHC or an issue with the wiring. If it were me, I would pull the tank and comb through the wiring, inspecting for any rub throughs etc.

If no issues were found I would either sent the EHC to WSW for testing or repalce it with another EHC or a TH/RIP.

Just a quick update. I ended up buying the Thunder Heart ASM4260 Module. I am waiting to get it in the mail and will start wiring it up. I will try and take pics as I go to help anyone who wants to wire one up themselves. I am wondering mean time about my circuit breaker. I talked to a local shop( victory shop but they work on big dogs) and told him the scenerio and he said may be the ehc and that he would look at the circuit breaker too. Could my circuit breaker be bad and it keeps tripping and bike dies and then it resets and then I can start the bike? Or would that not cause my issues? Also when bike is on, voltage is 14.6 volts. If I give the throttle a little twist I notice the voltage drops into the 13's until the rpms go back to idle. Is this normal? Thanks

No. Too many movements to restart, and if you don't get the sequence down, it won't start, right? So it won't start right back up. The breaker lets the bike run up to the point you step on the brakes or something? If it was the breaker, it would heat right now and turn the bike off. Sounds like a breaker now?

Normal. With lights on all the time, the 5v for the black box, the taillight, the coil, etc., the bike pulls more volts out the battery when idling, right? So it lets more current flow at low rpm. This rpm now meets a threshold, the excess is triggered and this discharges the excess to ground, being the bike is making more current the more the crank spins.

Ok I haven't had much time to do anything lately due to work but I am getting ready to throw in the thunder heart module. I had an interesting thought that I wanted to run by you guys before I start tearing into the wiring etc. The 2 prong connector on front left case of motor, this is for voltage regulator correct? I noticed on mine that it looks like it just barely plugs in, like a loose house socket. So my thought or idea is maybe this doesn't always make good contact and as a result my bike is low on voltage and when I add extra stress on voltage by using brakes or blinkers etc, my bike shuts off and horn blows( low voltage indicator).....does this sound like a possibility? I pushed on the connector hard but it doesn't snap in or click it just sits there like the holes are loose....any thoughts?

Take a picture and show it to us. There is a screw to hold it in place.... allen screw front of primary.... check if it is still there. See the hole front of primary - near the stator/VR plug?

Well you have done a battery test and passed, stator test and passed so that plug you are referring to is working fine. I think you have some bad wires. You need to chase the turn signal harness on all four housings make sure the wires are not bare. Have you looked at the wires under the tank, they may be shorting out. I think the horn sounds when you run the battery down. But to me it sounds like it's either a bare wire that is worn through and is shorting out under the Gas Tank or in one of the signal light housings. Chase them out or you will never find your problem. It may take a little work especially with the rear harness because you have to take the rear fender off, but you will have peace of mind when you find out if its the wires or not. The Tank is not too bad just make sure it empty (less weight) every harness is plug and play either under the tank of rear fender on the right side of the Battery. Keep in mind that with all the vibration and heat these wire will wear though and cause problems. My :2cents: on this.
BTW if you find that wires are bad, replace the rear fender harness and the two front harness. Call Donna at 620-257-2009 they should have some available.

Sorry to hear about you electrical troubles, I hate electrical issues!!! About a week and a half ago something similar happened to me, First my tach died on me during a ride, finished the ride and parked it. A couple hours later started it up and when to head out and the bike died, horn kept beeping and the flashers came on. Ended up starting back up and was able to get home but the tach was all screwy. After alot of messing around, it ended up being a short in my licence plate bracket light, one of the wires had broken off the LED board and would short out occasionally due to the bike vibrating. I got lucky, cause after messing with it for about an hour and a half, I was reving it up and just happened to see the light flickering.

Sounds to me like a similar problem your having, a short somewhere. Hope you find it

The bolt is still there, its not loose and moving around, just seems loose as far as the prong plugging into it. So basically when I plug the prong connector into it, it doesn't click or snap in, kinda seems like it just rest in there.

If the bolt is in there you should not be able to unplug the prongs..... to be able to plug/unplug, the bolt needs to be recessed first.

Carlos I unplugged the rear lights and still died and also the rear brake makes the bike die so that rules out the front lights. I did check the under the tank and found a few wires rubbed, one being the wires for the right pcb board and taped them up with no change. The problem is intermittent and does it riding or sitting, a bare wire shorting would happen all the time wouldn't it? I didn't know if the vr plug is maybe vibrating away from the stator connector and shorting?

Thanks, I seen your post and went and took apart my license plate, haha. Didn't find any shorted wires, a few bulbs out though. Glad you found your culprit!:oldthumbsup:

Did you check the rear brake wires under the rear fender?

I disconnected all the plugs that run to the rear. Its not just the rear brakes, its front or rear brakes, left or right blinkers, headlight, anything that uses additional voltage. I also disconnected the pcb boards one at a time and didn't change anything.
