Illinois... bike has been in the garage all winter with the battery out. I think tomorrow I'm gonna pull everything apart and make sure all the connections are dry and clean

OK i thought it was not spinning over corectly.. its probbly a lose connection or week battery then.. have you checked the charging system? just to make sure you have the correct voltage? these bikes will kill a bettery is its not charging corectly.. & when you had the hand control make sure you didnt nick or pinch any wires.. that makes the ehc go crazy.... or for that matter any connection that may be pinched.. under the tank included.. this can drive you crazy.... just a thought...

Hmmm.. when the bikes came from the factory.. was there some sort of foam or anything between the EHC and the tray? I'm just wondering if maybe the vibration is causing an issue?
nope I just did it to mine as a precautionary thing..you know hard tail n all..

make sure there tight,when i first plugged in my new ehc i thought i plugged it in all the way,i had start,the no start,someone else did the same thing.good luck let us know how it goes:cheers:
 
Sorry, I don't recall all the details about the battery. I only know that it was the biggest battery Harley made, the thing completely fills my battery box with no room to spare, with high cranking amps something like 440 CCA. With BDs proprietary low voltage electronics if the juice drops too low they want to reboot the computer, EHC, which causes weird things to start happening.

No... you don't want dry and clean. Clean yes. Dry NO. You want di-electric grease in those connections. If you removed the grease from the big EHC connections that is probably your issue. Pull them, pack them FULL OF di-electric grease and re-install. If you have a broken connection screw. Zip tie them down to the ehc.

Check the battery as said. Needs to show 12.8 or better when the bike is sitting. Then at least high 14s when running.

The right hand control is also a thing to check.

Further, being its a 2005. You replaced your EHC. Did you check under your coil mount and see if you had the pigtail resistor still hooked up to the ignition key. See below link for more info

It was a fix for the older EHC but is suppose to be removed when you installed a new style. A repair or band aid for the old version that is not need and will cause problems with the new version. If you have this. I'll bet ya its the problem!

Check for the diode Gas Man spoke of. Sounds to me like there is a short or loose connection somewhere that is causing the EHC to shut down to protect itself and thus shutting down the bike. Look for loose wires in crimp connectors at the battery and else where. Check the ground wire coming from the battery to the starter bolt for looseness. Look for corrision on the tach board in the speedo, you will find this at the bottom where water will settle. Finding this type of problem can be difficult so don't give up. The wiring system is not that complex once you get past the EHC and handle bar switch boards.

My 05 ridgeback has had those mounting bolts broke off the EHC for quite some time now. No issues here with that. It does sound like loose connections at the EHC and also problems with the hand controls. Hand control board is a cheap fix also. Keep reading what these guys say. They've taught me a whole lot about mine by just reading in here. You'll get it. Don't give up.
Another thing to search in here is those spices that are under your tank. There is a ton of non protected splices under the tank. I've not pulled my tank like a lot of guys here have but they have definatley benifited from cleaning those splices up.

Well Gas you beat me to it... :2thumbs:
gaddog I was having the same problem with it shutting down while riding down the road... If it happens again remove your seat and see if the EHC is all lit up.. and read the link Gas posted you can also check out my other link during this problem http://www.bigdogbiker.com/forums/help-wanted/4036-bike-shut-down-after-40-miles.html I have had no problems since removing the resister....:2thumbs::2thumbs: Good luck and let us know whats going on..

The issue of the bike just all of a sudden losing ALL power, then magically coming back to life is EXACTLY the issue I was having with my '05 Chopper. Be riding along, then would notice the tach doing some funny things, typically followed by the speedometer either maxing out, or just going to zero. Then, within a few seconds, TOTAL SHUTDOWN, as if someone came along and yanked the battery out of the bike. Would check all electrical connections, then after about 5 to 10 minutes of waiting, would try the key again, and presto! All was back to normal.

At first this was VERY intermittent, occurring maybe a couple times a year, and always when I was either stopped, or creeping along thru a parking lot. Then it got worse, and was happening about once a month, AND while cruising along at full speed. It was also the same 'ol story... pull to the side of the road... bike TOTALLY dead... wait about 10 minutes... and all was back to normal.

Not willing to throw a bunch of time and parts into it, and suspecting a thermal trip of some sort was occurring in the EHC, I ripped that damn thing out and replaced it with the Wire-Plus system. Since then, in about 3000 miles and several months, I've had NO ISSUES!!!

Good luck.

That's why I love this site.... 2 days... and tons of replys...
I'll be checking all the connections, running the lines to check for crimps and check the voltage tomorrow...

Thanks guys... I'll keep yah upto date

Sorry that I haven't gotten back to everyone with the results. Unfortunately I came down with a bout of kidney stones and ended up with (2) trips through the E/R and an overnight hospital stay and a surgical procedure involving a part of my anatomy that I normally consider an exit. Looks like it's going to be a few more days before am well enough to be able to start twisting wrenches but as soon as I am... I'll let you all know what the results are.
