I,m going to try one more thing on the connections at the EHC. Possibly heat affecting pins on connectors & ehc. If that don,t do it I will get back to you Kickstart & see how we can get that one you have up here. I have about 3 weeks before it goes to new owner. This bike has less than 1000 miles on it & this is the second ehc. First one went at 250 miles under warranty. I have not ridden this much as you can tell. Got other bike & not as tough as I thought I was for a rigid.
Need help fast

Great for anyone who has not had an EHC problem. Problem is, they are problematic. You might luck out and you might not. When mine shut my bike down at 80 mph on the freeway my ass was puckering. I could nave had real problems. EHC's are BS and there is no reason to have them. In the first year I owned my Dog I broke down (electrical) at least 10 times. I had to buy a trailer to get back from places. The second year was the same. I was fed up and was going to buy a Harley again but I decided to hardwire the whole bike. 12 years later and I have not had one issue with the bike. I sold my trailer and would trust the bike anywhere.....why?.....I removed that fucking POS EHC! This site is dedicated to electrical problems. 1% of the problems on here are mechanical. Do what you want, I'm gonna ride my bike. EHC's are like fat chicks.....there really isn't any reason for them.

Likewise, I'm on my original too. 78,000 miles thru rain, cold, and desert heat. Never a problem. Dielectric grease every spring and ride it!!OK.... I´ll say it once again.... I AM ON MY ORIGINAL EHC, dated 2005, ...... Clean & Tight and dielectric grease!
Stop blaming the EHC! 95% of the problems I´ve read here blaming the EHC were wrong!!!

I thought you replaced your EHC because it went bad?

Glad to here from the relentless maintainers out there in BDM land not having problems with their electrical systems. Let me see what your saying "I have to do" to drive my big dog. Each Year I have to remove the gas tank,wiring harness and various other components. Pull all the JST connectors, clean out the di-grease from last years work, reapply some new di-grease, connect all components,test and put back together. I have never, ever had to do this with any motorcycle I have ever had. Just to keep the EHC..
I do not and will never use an EHC again. If I purchase a new big dog, out it comes! I have ESC from DOC's, did the job one time, don't have to do it ever year. Too each they're own pain. I vote for a forum poll. Then we're not guessing 95% of the problems are not related to the EHC, they're all related to the electrical system which is operated by the EHC. Just sayin..
I don't think your old Harley Battery has the ball to turn over your BDM.
You need to get good battery, I use the TR B-1500 which has 465 CCA and it turns that baby like top no matter if it's cold or hot. They are pricey http://www.tomiokaracing.com/index....t-batteries/tr-b1500-lightweight-battery.html, but it can handle the load. You don't need to spend the kind of money I did for at battery, just get a good one like a Braille or Even a H-D battery but with at least 330 or more CCA. Buying a cheap battery just to sell the bike is not the answer. I am just trying to help you sell it. If the horn is stuck, the lights flash and it does nothing else "ITS THE BATTERY"
. Get a good one charge it up,( not a battery tender) for at least 24 hour (slow charge) and if it doesn't crank then you have more than just an Electrical Problem. You have to get it to crank and it is not doing that, so don't blame the EHC.
Get the Bike to crank and if it doesn't start we can diagnose it from there.

Yeah, Franco is probably right................it's probably the Wheel Bearings!!!!OK.... I´ll say it once again.... I AM ON MY ORIGINAL EHC, dated 2005, ...... Clean & Tight and dielectric grease!

Ok, from my experience, my EHC is just fine and in the parts box. It seems to me that it was just too darn sensitive to voltage changes. My Wire Plus has worked much better with more reliability. But, whatever you go with, there is a chance of issues.

I don't know about your bike , but my EHC isn't under the gas tank. The 10 min it takes to check the EHC connectors for not vibrating loose over 10-12,000 miles of riding and adding a little grease is not a big deal to me for the enjoyment I get from knowing that when I leave home I probably won't be broke down along side the road. But to each his own.Glad to here from the relentless maintainers out there in BDM land not having problems with their electrical systems.

My bike has never stranded me but has caused me grief. Every Spring and Fall I have to do the hair dryer trick to get it to function properly, but once I do that it runs fine all day. Living in the Northern portion of the US seems to cause more problems with the EHC. Going to be changing mine out soon, just not sure if I should go with DOC's or Axel's. Replacing the harness under the tank is a plus in my book as well as the Charging System/Battery Fault option. I have tried a couple of different EHC's and they have all responded the same as the original.
Does anyone know if Axel's replacement is compatible with DOC's harness?

No, Axel's will plug right into the OEM harness, Doc's ESC replaces the harness and the connector is different for the Thunder Heart module in the ESC, I have installed an ESC about 6 months ago and I did get the optional voltage monitoring and with the wiring harness going straight to the headlight, no connections under the tank for the headlight, along with the ceramic headlight plug, is also a bonus. There was just a post last week that a member melted the plastic headlight connector. Good choice with the ESC
Well great new an interstate battery that works
. Now you're good to go and it wasn't the EHC. Carlos
My EHC brain is under the seat just like yours, and you know it. No need to be a smart ass. Yes, I did the bull shit clean from the mother brain each year till if farted out finally. Takes me longer than 10 minutes but I'm old & stupid. No it's not a big deal just the clean that portion of the EHC. But that's .25 of the actual job for electrical problems. Now I do have some experience begin broken down on the side of the highway because my EHC and electrical system didn't work. Oh but you cleaned yours and never had a problem (great for you but not-so-hot-so for me).
I spent hundreds of hours and lots of money troubleshooting the issues cause I listened to folks on this forum that "know better" to no resolution what-so-ever! That was a big fat waist of time and money. I did eventually listen to a few kind hearted members that told me early on to change it out but I was pig headed and well did like most others tried to isolate the issue but again didn't work for me. In hindsight I didn't need a new battery, starter, regulator, ignition, or any other part I replaced. I needed an electrical system that actually works with a brain that doesn't fart or need warmed up cause it a bit chilly outside. So if your motorcycle is a BDM and your horn is sounding for no reason, while your four-ways are a flashing, or you bright lights are on without turning them on, all while your bike won't crank, then all of sudden it starts up then shuts down, but all this disappears only when the EHC is "warmed" then I offer to my experience, before they break down on the side of the road like I did, my opinion and you should replace the EHC and wiring harness! Just sayin..
Hmmm.. this is interesting, in order to ride my big dog, I must take a hair dryer to the EHC and warm it up.. Anyone have to do that for say a Yamaha or HD?Well great new an interstate battery that works
Carlos
I totally agree EHC is total crap. Surprised there wasn,t a lawsuit before BD went tits up. But anyway, I was going to do away with ehc this winter but dam snowstorms kept me too busy to do anything else. I found a bike this spring that I liked (yes an HD) & decided to just get rid of the big dog rather than to rewire. May regret it but it is a done deal.

There was a lawsuit I think. There was also an EHC recall in 2004. "Intermittent power loss"
The problem in 04 was the connector it wouldn't stay connected.
16 years later and Axle remade the EHC and he is mostly worried about that 50 pin connector. Not made for high vibration environments.
