Hello, Need Help

I have a 2004 Bull Dog, showing a short. It seems the EHC was removed by prior owner so I can't follow BDM wire schematics. Traced wires to a rectangle box beside the transmission, several wires going into this box, I'm assuming some sort of controller. Printed on side: BDM P/N 171-000076-00; PWI P/N 6900334-001......I have searched online and can't find what this part is.....any help would be appreciated. Thanks Dave

Ok, I apologize for my ignorance from everything I've read it talked about lights on the ehc and located under the seat, since there were no lights visible on this piece and it's location down by the tranny I assumed something else and figured ehc had been removed.

No need to apologize, that is odd and it really hard to see by the pictures. Also most ehc’s that I have seen are under the seat.
And the ehc should have lights!

I wonder if it’s a older pdm ? Most ehc’s the wiring harness plugs into it, that is a strange ?

Failure of the HCI in the PDM was somewhat common. My advice would be to change out your battery box, replace your main harness and put an Electronik EHC in the bike. It will get you back to a reliable system that is still almost stock and easier to maintain and work on by you or others.

Hey Guys,
Thanks for all the help. I'm going to fill you in a better on what's going on and pick a little farther. Everything on the bike seems to be working. The issue started after I went to start at the beginning of the year and my battery terminal got hot enough to melt the positive side. I replaced the battery, once hooked up the blinker indicator lights on the speedo lit up(key on or off didn't matter). I then started testing wires following sources from these forums. At that time I had two wires showing shorts one to the VR, I tested and replaced, went ahead and replaced the stator as well. After putting everything back together no more short from the VR wire(yay), bike fixed... not. When i hooked up the other wire, turn lights on again same scenario. I am at the point of replacing PDM system as Curtis and others have suggested, however, I'm thinking this is the system that someone has already replaced the EHC with so I'm hesitant to shell out the $$$ to replace with another system as well as I read one guy that had done this and found out that the short was in an existing leg and still remained after his change out(I don't want to be that guy). Here's where I'm at: Is the short in the annunciator(tach), the wiring or the HCI. It seems like a process to check but my bikes in pieces so any advice or knowledge of the best ways to rule out each one would be appreciated. BTW the upside of this is I have never worked on this bike myself and am learning alot. Although my first thought was this guy seems a little crazy....Marks Asylum on you tube has been great! Thanks in advance guys and sorry for the rambling. Dave

BTW, no disrespect meant towards Mark....He's down to earth and his videos are very helpful

Have you checked the battery wires?
Also may want to check the fuse, I had a voltage regulator burn up due to the fuse being bad, and also ensure it’s set on the proper side of the relay/fuse ? I think it’s attached to the silver side of my memory serves me correct.
Check the wires with a volt meter for continuity
