Yep that's your ehc for you. No here is the kicker half of the time it's in the ehc and half the time it's in the wiring harness. With axles you only get the ehc. With DOCs you get a ehc and a wire harness made specifically for your bike , year model and plugin play to fit into whatever ehc system your bike currently has. It usually take a couple of weeks to hand make your specific harness. You also get a new ceramic headlight plug and harness. And an battery system charging option, which I highly recommend. I got that and it told me my VR was starting to go out way before it did and fried anything. So you can get a good half system that is quick to put in or you can get a great full system and not have to worry about the ehc and any part of the harness in the future. Ppl report harness problems seams like as much as actual ehc problems. So do it all and not have to worry about any part of it or do half of it and hope the other half holds up. Me personally only want to have to fuck with it once and done.How much does that cost? I'm having some weird issues as well
So what happens if you spend 600.00 replacing the EHC and it has nothing to do with the problem??? to me its not ehc related due to your symptoms. I don't know allot about the fuel injected systems but IMHO your issue does not point to the EHC.. Why not send it out to get tested first. Recommend curtis at wild steed work..i have a 2008 EFI Mastiff. I've had some electrical gremlins from the day I bought it nearly 5 years ago. Had the bike looked at multiple times and the problem has never been diagnosed properly. The main issue I have is that occasionally when I turn the bike on the fuel pump will not energize. The bike will crank but not start. When it starts and I ride it, it will run great for a few miles then the engine light will blink on and the engine will stumble. If I'm on the gas I can keep it running. If I'm decelerating, it will likely die and then I have the starting issue. It seems after the bike cools down it will start properly.
The starting issue was intermittent. It might have happened 4 or five times a year the first 3 years, but would always start after I went through a bunch of diagnostics and maybe replaced a part. The engine light issue started a couple years ago, but was intermittent. My mechanic couldn't find it and suggested it was time to replace the EHC. The following has been done with no success.
1. Grounds inspected, cleaned and re tightened multiple times. Each time thinking this was the solution.
2. Relays replaced. Again thinking I fixed the issue. I have a bag of 10 and have replaced and likely thrown away 3 or 4 good ones that I was convinced had fixed the issue.
3. I've replaced the ignition switch. I now just switch between the 2 for fun so I can show my wife that I can fix the bike in 20 minutes!
4. I've replaced the circuit breaker so I can show the wife I can't fix the bike it 20 minutes, but that switching back to the original does!
I'm finally at the point I'm ready to buy a replacement EHC.
My options are:
1. Just buy another EHC from Curtis
2. Buy an RIP gen 2 kit.
3. Buy a DOC ESC kit.
I'm leaning towards option 3. DOC has helped me over the last couple years to try and diagnose this problem.
Thoughts or advice?
Very true. If your going that direction have harness checked second.So what happens if you spend 600.00 replacing the EHC and it has nothing to do with the problem??? to me its not ehc related due to your symptoms. I don't know allot about the fuel injected systems but IMHO your issue does not point to the EHC.. Why not send it out to get tested first. Recommend curtis at wild steed work..
from their you can rule that out and may save yourself 600.00 plus any additional cost to fix another problem.. that is where I would start.

I spoke with Donna last night and I think they will be there today. Best to send her a text and she usually gets right back. They must be busy .
Well I guess we agree on textingWith all kidding aside it seems easier to text and when she returns the text if you really need to speak with her that is the time to call she will answer
Your choice in the matter and probably not a bad move.Let me add a couple more points of information.
1. My mechanic hooked up to the EFI controller and could not find any stored faults. DOC told me that what I was experiencing was "limp home" mode when the engine light would flicker. Once my mechanic had the bike for 4 weeks he could not duplicate my problem. He cleaned and replace the small wire ground - he felt it was suspect. I rode it for the entire summer with no issue. Yet it returned that fall (2015).
2. I've replaced the fuel pump, but for another issue.
3. The singular issue is no power to the fuel injectors intermittently while riding. If the bike dies then when I hit run the fuel pump will not energize until the bike sits for awhile. Maybe cooling down is the issue, but I've been successful starting the bike after only a minute or two as well.
4. Every component in the fuel pump circuitry has been replaced and the issue has occurred with both old and new components - except item 5 below.
5. The only components that remain are: the EHC, the S&S EFI controller, the wire harness and the hand control switch.
6. I don't really suspect the hand control since it only provides the initial on signal and that signal is then held on by the EHC. I seem to drop power when I'm riding - momentarily and it sends the bike into limp mode for about 1 second or less.
7. That leaves the EHC, the S&S EFI controller and the wire harness. I'm certainly concerned that it may be the S&S EFI controller. However I can't say I've ever seen a post where someone had to replace it.
I'm basically resigned to giving into the "EHC is junk" mindset and going for the DOC ESC replacement. I haven't been able to ride the bike since October 2015. I've been distracted by a job change, a move, new house and finally (thanks to the wife) a new beautiful Road Glide last spring. So I'm riding, but missing the dog badly.
Looks like I'll buy the DOC ESC later this month
Yep, staring at it seems to work well. It's also been helpful to replace a component or change back to an old suspect component, but I've found it's easier to just stare at it.I'd say wiring harness but it sounds like you don't touch anything and it fires up after just staring at it for a bit?

My best story for this problem is as follows:
Yea EHC...and that's a bummer story.My best story for this problem is as follows:
Decided to go meet a friend for a day of riding. Got 4 or 5 miles from the house and the bike dies when I pull up to a stop sign. Bike won't restart. Fuel pump won't energize. Call my buddy and he shows about 20 minutes later. Bike still won't start. I call my wife and she comes and gets me. We drive to uhaul and get a trailer. We return and I can't get the bike on the trailer because the frame drags. So I'm pissed and decide to try and start it. It fires right up and my wife follows me home.
After re reading your post I am wondering if there is a issue with your cam sensor, ignition module.i have a 2008 EFI Mastiff.

How would either of those two components cause the fuel pump to not energize when I hit the run button?After re reading your post I am wondering if there is a issue with your cam sensor, ignition module.
I'm thinking seriously since it's efi, correct, your problem is in your efi unit. Or harness between esc and efi units. Guys correct my if I'm wrong but there is no ignition module and all pumps and spark are controlled by the s&s efi module. Now you may have some electrical issues between the esc and efi connections cause the esc runs the start button then sends signal to vfi to run the pump then vfi primes the pump. I think that is how it works!How would either of those two components cause the fuel pump to not energize when I hit the run button?
If I understand it correctly, the EHC provides relay power to the fuel pump through the EFI. The wiring diagram appears that it's just pass through. The EFI regulates the amount of fuel via the injectors. Since I don't get the pump to energize I'm assuming it's the EHC. The intermittent stumbling of the engine has never been caught by a computer hooked up to the bike. So I can only assume. But since I have the starting issue immediately after the engine stumbling issue, I'm assuming the power to the fuel pump is cutting in and out for a 1/2 second or so.I'm thinking seriously since it's efi, correct, your problem is in your efi unit.
