Yes it was the old ehc pin 37 was no longer reading to the other groung pins.

So it was the EHC and not the wiring harness?

AH back home, much easier than on my phone.So it was the EHC and not the wiring harness?
Still don't think the external ground wire had anything to do with the new ehc going bad? At least I hope not!!! Maybe the old ignition module? Works sometimes, sometimes not? The new ignition system will also have a external ground. It gets mounted in the nose cone of the motor. Nothing I can do now but wait for more parts.

If the old one was mounted on the rear fender, will you have to add wire to the harness for it to mount in the nose cone?AH back home, much easier than on my phone.

Yes I ask for a wiring Dia. from Curtis, he said it comes with one. Haven't got it yet. Not sure until then. I believe it will be like my Crane HI-4 that I put on my Harley. It's be on for years.

Tom @ground pounder has one in his spare parts hoard, maybe he can measure it for you if he can figure out how to read his meter. LolHm, we´ll find it not out exact. There are only some speculations include my own. Hope to get your bike back on the road soon
However does somebody know if the ignition coil of the EFI version have the same resistance like the coil in the cabureted version? I know from Harley bikes that some injected bikes have a lower resistance what drives more curent through the control box. What about the S&S?
Thanks a lot!
All the best!

The EFI coils are for sure unique.

Hi Jwooky,
Thanks, It´s alredy not necessary to measure the resistance. I had seen that the EFI ignition coil is feeded direct from a 25 Ampere fuse and a relay. So, there is no load on the EHC. I have looked to EFI schematic several times but have always overseen the relay. Bigger eyeglasses ???
By the way, I have potted a few EHC today. I still need a bit experience with the quantity of the potting compound but I think it will work. It still looks a bit raw due to the potting material on parts of the metal sheet.
I just have put one EHC in a few socks and have put it in our washing machine for a small "hardcore test". (My wife was not very happy...). I´ll come back to you with the result tomorrow.
Do you know this pic ?

Yes, the EHC still works on my tester . So, I´ll bring 3 EHc on the way to my distributors in order that they can make the test at a bike what is more realistic than a simple tester what will not draw high currents through the EHC.
By the way, I overworked the software yesterday and added 3 software options:
- The flasher can flash 3 times before it will switch on permanent.
- One software option will lock the start / stop buttons against each other. So, the customer can not start the engine a second time if the engine is on. He need to push the stop button before the start button is enabled again. The disadvantage could be a bike with a low battery. This might result that he need to take the time to push the stop button and wait for a moment before he can try the next start. However this function can be disabled at any time. The advantage is that software will do always the job compare to an engine sensor regardless if snow, rain or mud is around.
- The head light is off when the ignition is on until a light button is pressed. This option can be disabled or enabled also at any time.
I attach the actual manual.

Axel,
Good reading. Question with the 2004 units. Would it benefit also with a relay and 25 amp fuse for the ignition / coil circuit? Use pins 13 or 14 to pick up the relay. That would isolate ignition circuit from the ehc. The new system I am putting on my bike is the http://www.wildsteedworx.com/index....info&cPath=65_68_174_180_211&products_id=1148
That way I could use larger awg wire like 16 gage when I install the new system? That did always worry me. In a house you must use 14 gage for 15 amps and 12 gage for 20 amps. Most of the wires on my big dog are 22 gage some 20 gage? The ignition circuit is 20 gage.

I could mount this where the old ignition module was located. Just want to get the bike as bullet proof as possible.
Thanks Todd

Hi Todd,
Thanks for the infos. Yes, in a home are different requirements where the cables are somewhere going through a tube in a wall without cooling air around or fixed with nails on wood (...)
I have looked to the link from Curtis. The coil resistance is 3 Ohm, what shouldn´t be a problem, cause it drives just 4 Ampere and the EHC can drive more than 10 Ampere without problems. The current will go down when the engine is running. So, from my opinion there is no need for an additional relay. However, the contacts of the 50 pin are rated between 5 and 7 Ampere depending of the brand of the d-sub and their measuring methode and the ignition 12 V is splitted in pin 13 and 14.
I´ll implement the new software in the new 2004 EHC as well. I have overworked the 2004 board due to some suggestions from Curtis (mainly the connector position, what was not perfect in the first version) and still wait for the pcb´s.
By the way,does somebody know the resistances of the 2 resistors what are mounted in the Big Dog Efi Kit WP383?
http://www.wire-plus.com/WP383--BIG-DOG-EFI-KIT_p_152.html
It´s connected to switched 12 Volt and to the 2 bridges from the EFI to the Low Fuel and Service Engine (whatever it mean...) led´s. Thanks a lot!
All the best!

Shipping my EHC to Curtis tomorrow to let him check it. If it comes to buying a replacement, I can hopefully have my 08 Mastiff up and running for Vegas 115 degree heat to provide a real world heat test for Axel's build. Based on how thoughtful his R&D was over the past 30 or so pages of this thread, I'm sure his box will last far longer in the heat than I will.

...Just an other story: I got my Ridgeback 3 days ago I already kicked off the original EHC (It was not very complicated as the screws were hanging at the holder and the box was separated already from the screws) and installed my EHC. Nice bike and more comfortable to ride compare to my other old iron. The only challenge are still curves with the 300er wheel but I get it better from day to day. A photo will follow after cleaning. It was a bit raining today..
All the best!
