EHC is now history

[Night Train]

Hey Night Train...
What is the difference, electronics wise, between this Thunder-Heart chassis controller compared to the Thunder-Heart units in 2003 and older Big Dog Bikes from the factory? [/QUOTE]

2002 and older is the Thunder heart module, direct replace. 2003 change the headlight and starter circuit around and a couple other minor differences that I am sure could be wired around.

I was wondering what the differences were from the Thunder-Heart module that BDM used back in pre 2003 compared to this new Thunder-Heart module that you just installed in the EFI bike?

Completely new design, a much better unit. Operation wise not much of a difference.

"Hey Neil save that ehc for me". Like we talked about it at work today I might be having problems with mine now. But I'll do all them checks we talked about. But would still like to have it as a spare thanks bro

Can anyone tell me the difference between the Thunderheart 4250 from the '01's and the BD upgrade replacement for this part? Second question, does anyone know if a brake switch being constantly on could burn out a component for the turn signals. Seemed to be the sequence to my problem. No turn signals. Fixed the brake switch problem.

So, with all the threads about EHC issues, I decided to take the plunge, yank it out and use the wire plus harness. It has taken me longer to do than what others have said. Of course I am an eraser eating, knuckle dragging, mouth breather so I tend to go slow when it comes to the tech stuff.

I am pretty much done for the most part. Initial testing has my right rear tail light out when I turn the key to the accessory position. Otherwise, so far so good.
My question to the others out there with air ride suspension...where did you mount your stand alone switch?

I know I am beating a dead horse but I am taking my 2004 Mastiff in this Tuesday to have my BDM EHC replaced with a TH ASM4260, and the mechanic assured me all I would need is this TH ASM4260. Is there any other part I need to take to him to assure that I have all I need for him to get the bike off the rack and running? As I read through this thread about the ASM4093 part it makes me wonder. I want to keep all the stock components that I can with as much functionality with the factory controls. Will I need a new ignition switch, and what happens if I hit the start button by accident while she is running? I would like to chat with anybody who has the time to answer some of these questions before D-Day this Tuesday.

Im wondering if anyone has tried the new BD change out.

not yet but they are available I just talked to BDM Friday about a new Speedo and they are shipping the electrical kits as ordered as soon as they arrive.

The BDM kit I think is $592 for the non EFI I have one on order
