Question for you guys. Years ago I got the HD Harness fix for my 1125cr. Last summer installed EBR rotor with a rewound stator(after mine melted). I am wondering if I should keep the HD harness fix or wire it back to stock setting considering my electrical system should work correctly with the EBR fix? I emailed EBR but they really didnt give me any direction as I know they can't make recommendations. Any thoughts? Here's their response below: People have been running either configuration, but we have not done long term tests both ways. You are correct that we do not use the H-D/Buell wire harness shunt and strategy on the EBR 1190RS. Thank you, Tech Support Erik Buell Racing | ||

Jimmy After reading thru a good bit of this It seems to me that the consensus is that with the EBR fix ( the oil jet ) that the relay harness is not needed. Review the postings here, several have done additional alterations beyond the stator & rotor, changing to a switching regulator, or a different shunt regulator One has even logged temp data from the stator on his bike while riding. Many have removed the "HD" fix, If I were in you position I would consider removing it... The relay is a wear out part not intended for the service that it sees, some have been found burned up / fused its your bike read and decide.. YMMV | ||

Thanks Oldog. I am leaning towards removing it but just waned to make sure there wasn't any real reason to keep it since I do have the EBR fixed rotor. I am leaving for a week in the Smokey Mountains and praying for no electorical issues down there  | ||

+1 for removing it. | ||

Thank you so much for posting this, the truth is priceless. | ||

Logically, since heat was killing the stators and H-D's fix reduced output from the stator to reduce heat, the oil jet that drops a good deal of heat(50 *F according to an interview with Erik) should be enough. Win-win since you keep the higher output and gain reliability. I'm happy with my 08. | ||

I also removed the H-D relay & harness after installing the EBR oiling rotor and determining that the stator and regulator were still in good condition. No worries now. | ||

Sparky- How many miles has it been since you removed the H-D relay/harness? thanks Mort | ||

I have 18K on my 09CR, stator at 2K. The last 15K without the fix. If I keep the RPM's up at 4,000 the bike is fine. I use the bike for the open roads and do not use it as an urban commuter. The heat of Stop and Go traffic kills my bike. A good battery tender is a must have, I resisted for a long time before I got one. http://www.youtube.com/watch?v=nBYEYGJfyBw&feature =youtu.be | ||

Thanks for the input guys. Last question. I've noticed with my current setup(rewound stator, EBR Rotor & HD harness), my charging while riding varies from 13.1 to 13.9 It seems for mine that when my rpms are under 4k the charging stays between 13.4-13.9. Over 4k rpms lows 13's. I think I am going to have harness removed. Should I assume that it will charge higher/better when I keep rpm's over 4k? Should I keep the rpms higher with that change going forward? | ||

In my humble opinion probably when you remove your harness you'll reach 14+. Lower RPM's on mine are right around yours. The higher RPM's I'll see 14.1-5 then back down depending on the RPM. Remove it..  | ||
| Jimmyb152 |
Jonesgw - Thanks, will be removing soon Dannybuell - Thanks for the link! Much easier than I thought | ||

@ Mortbike, it was about 1700 miles ago I removed the harness "fix" and 3 failed relays. | ||
| Yugi |
I removed the harness 2k miles ago, after installing EBR rotor, now at 3500 miles on the stator. Still good, but too early to say. I'd like to wait until I'm at least 6k on a stator. | ||

Damn, i was just planning to remove my HD harness fix when I looked and my wires were too short when I replaced my VR with the compufire... Im thinking of just making an extension of the wires.. What gague wires does the bike use? | ||
| Yugi |
I can make a cable connecting stator connector to a Compufire connector. Look in this thread: http://www.badweatherbikers.com/buell/messages/290 431/664657.html | ||
| Bartone |
damn, I should have gotten one of those instead of splicing the old VR connector onto the compufire.... Can you make one that has a deutsch connector on both ends? | ||
| Yugi |
Yes I can, but I need to order parts for it. Let me know. (Message edited by yugi on April 17, 2013) | ||
| Bartone |
I think its just easier if I ordered the parts from the links provided. Costs about the same, less hassle. Thanks though Is there a certain type of 12 AWG wire i should be using? Im not too familiar with wire types | ||
| Jimmyb152 |
It's me again - I did the bypass back in April and worked awesome as I have EBR rotor. I left harness in the bike because there were two other small wires hooked up and I didnt know if I should unhook them. But I just got 12k maintance done at HD and they re-hooked up my harness. I now want to remove the entire harness, can I just unhook the small wires? will that cause any issues? THanks!!! | ||
| Jimmyb152 |
Ok. I removed the harness. There are two male hookups(#1 & #2). Do either go into the female hookup picture? Or should I tape off all three?  | ||
| Jimmyb152 |
To clarify a little further, #1 plug goes to solenoid. I'm thinking I would just tape it off. #2 goes to ECM, dont know if I should plug it into the female. I dont know where the female goes but it was hooked up to warranty harness. Any help appreciated! | ||

Jimmyb, after removing the Harness Fix, if you just tape the small connectors, that can cause problems. So, 1) tape over the connector from the ECM with black wire (s) & sockets - they are not needed anymore. 2) Connect the 2-wire connectors of the bike's harness that have gray and gray/orange wires - those are for the Active Intake Solenoid. That should do it. For peace of mind re the Harley dealer rehooking up the Upgrade Harness Fix: I'd have them make me a copy of the B-099 Service Bulletin describing the Charging Sys Upgrade Program 0507. You are the customer and they should do it as a Goodwill gesture. It has a complete description of the installation, diagnostics & a wiring diagram of the harness & relay. | ||
| Jimmyb152 |
Sparky - Thank you very much! I have taped the ECM connector & connected the solenoid connector to the female harness. I think that should do it | ||

I may be buying a CR with known stator issue so I was reading this thread and have a question. Wouldn't leaving the harness in be extra insurance? Electrical issues are my weakest point with bikes so I am pretty much a beginner here. My old CR had voltage spikes and the vr relay in the harness fix failed before anything else did so if it is removed what happens if voltage spike occurs? | ||

Keeping the HD harness fix actually hinders your charging system. The harness shuts down one leg of the stator, decreasing charging. They did this to keep the temperature down. The EBR rotor cup decreases the temperature. If you upgrade your voltage regulator at the same time you shouldn't have to worry about voltage spikes. A lot of us still have the factory regulator and are doing just fine. I'm at 19,000 on a factory regulator and the EBR upgrade |
