My wife has an '03 Mastiff and she has an EHC in her bike. That's what I call it anyway. It's a solid state unit where all wires plug into mounted under her gas tank between the tank halves on the frame.Brother,
I'm not a 100% sure, but I don't think that BDM used the EHC in the '03 models. I think it was the Thunderheart controller then. '04 is the earliest ehc I've heard of. But I can be wrong.

G, it's been a long time since I had my 03 but I think the controller (EHC) is a Thunderheart unit so you might give them a call (ask for Brooke) and they may be able to send you the schematic.Yes I have power and my battery 12.7 v ,Now if I take the ground wire out of the EHC and turn my ignition key my bike start ,if I do the ground back it do nothing if I push the start button , now I took my feul tank off because the EHC is between the tank.
Than also on my battery the litle box the yellow lite is on when I turn the ignition key.
But I a couple wire where loose in the connection to the Ehc module and now I really don,t now if I have the right wires in the EHC , IT,S MY ON FAULT tHAT i DID PAY ATTENSION WHEN i TOOK THEM OUT.

G is from Europe so give his some slack.English my friend. :roll:![]()
That's not even close Dead. I thought I had a pic but can't seem to find it. It has a large 9-pin plug in on one end and a couple of 6-pin plug ins. The wire going to the speedo also plugs into it separately. I'll keep looking for the pic, but I don't have a schematic.G,
This is the '04 EHC, does yours look anywhere near like this?
If not, it's the thunderheart controller.

What you're describing sounds like the Thunderheart Controller. :2thumbs: But then again, what do I know? :loony::crazy:That's not even close Dead. I thought I had a pic but can't seem to find it.

G, can you take a pic of what you have and post it?

Didn't you say earlier that if you moved a ground wire, that the bike would crank? I may not have read that right or maybe didn't understand what you said.
