    So I went out and was looking at it. I found 2 wiring diagrams the one for the bulldog has more detail. Looking at it all. It’s the high beam that’s out. I split the loom that goes into the backbone. Found 2 white wires. 1 is hot with the key on and the other isn’t. I went after the white wires since that’s what colours the options were and based off the diagram. I know one goes to the headlight and the other goes to the left hand control. I have a pic of something in the diagram and am wondering if there is any relays. In the second pic I noticed this thing on the ehc where the silicone has been slightly rubbed off. Also would I be able to look at the ehc and possibly see something fried on the circuit board?[​IMG][​IMG]

    So you got 12v on the yellow wire and you cant get any voltage on white?

    There's really no way to remove the potting from the EHC to look inside. It is possible your high beam Relay is shot but I did you try jumping the pins in the hand control board to see if it's not the board?

    Looks like the ehc is fried in that one spot that potting shouldn't have a hole in it

    Look up under the front of your tank, find the two bolts, loosen the front and remove the back.

    Put a 3/8" extension in the square at the front and turn.

    Pull the tank to the rear of the bike off the rear rubber mount.

    Before anything, drain your tank and remove crossover line.

    How do I get to my highbeam relay? I actually removed the entire hand control to see if that would change and it didn’t make any change at all
    Ya I wasn’t sure. It looked like something was rubbing on it and then when I wiped away that’s when I saw that little bare part.

    Bday. Ty. I pulled the bolts out of it and my issue was getting the front to turn so the bushings would release the tank. I didn’t even think about using a ratchet and turning it so thank you again

    Oh. I removed them both. I want to a shop today that deals with big dogs a lot. He kind of looked at me funny when I asked them about the high beam relay he said to his knowledge everything is controlled through the ehc

    Yes the high beam relay is part of the EHC.

    *update*
    So assuming the EHC is bad I went ahead and put the bike back together and still have the flashing high beam indicator and unable to activate high beams on the switch started the bike up it ran for a few minutes and then died and will not start the EHC Has red lights flashing back and forth on the top two and on the bottom row the fourth light is red so I’m wondering if it was dying the whole time and started off with the high beams and then died the rest of the way. Any ideas or thoughts?

    I'm assuming you did not have the ehc tested? My guess is it's time to order axles ehc.

    No I did not have it tested I just thought that with the new light going red after having the headlight issues that it is most likely fried not to mention the epoxy or whatever they call It has that hole in it. Is there any way to repair it if it does test bad?

    I know this was mentioned before and I didn’t read through all the post. I had the same problem on the pitbull awhile back. After about 6 months of trying everything I found one of the pins on the jst connector was loose. It was still seated in the connector so I wasn’t easily noticed. I found it by gently pulling on the wire and the pin wasn’t locked in and it pulled out. I replaced the male pin and sure enough problem fixed.

    Which part of the issue what are you having? Was it the headlight issue or the not starting?
