Hey i just swapped out my 77 connector(thanks Al at American Sport Bike). Of course I pre marked the two black wires coming from the VR to line up with the black/red wires on the other side of the connector. Soldier'd things up nice all looks good. My question is; if I were to ever get a new VR cause my old one failed, assuming it'll have the new 77 connector, how will I know the proper black wire is lined up with the correct wire on the other side of the connector? I mean they're both black coming from the VR. The instructions with the new connector did not mention which black wire went into which slot. Or I suspect it doesn't matter which black goes to red and black on the other side of the connector - thus that's why they're both black. Can anyone confirm this? Thanks. | ||

Yes it matters, that's DC at that point and a very good question! We need someone with the factory new connector (08+)? to take a picture to make sure we've wired the the right way. | ||

It is important as Ronmold has said but it is very easy to check if you have a muti-meter - the negative wire is connected to the metal case of the regulator. The negative output wire will measure 0 ohms to a bare spot on the regulator case. I've got a photo of a gutted regulator but Imageshack won't co-operate at the moment.

that's a great idea Rays, except we need a brand new one with a new connector to run the test. I've already got mine sorted out and aligned right, the question comes in if I ever have to replace the VR, will the proper black wires be on the correct pins? And if my information is right, the 06 VR had 2 wires, whereas the 08 has 3. Not sure about the 07. Or am I getting this mixed up with another part of the charging system? Again, I defer to the experts - thanks Ron! | ||

" I see"; said the blind man. I missed your point entirely. I have a new regulator for my '06 tucked away in the shed - I'll open it up on the week-end and see what sort of plug it has. As to the different year regulators, the pre-'08's have a 3-phase input from the stator but the '08 & '09 (I assume the '10) have a single phase input from the stator. All of them have a 2-wire DC output. The connectors for the "08 and later are very different from the early ones and are crimped and moulded - completely unserviceable in the traditional sense. They are not without sin as there have been a few posts here about connection related charging issues but nothing like the number you see for our old friend the '77' connector on the '06 and earlier XB's. | ||

Thanks for the clarification Rays. That's sort of what I thought(all VRs have only two wires) but wasn't sure without actually seeing them. That would be perfect if you have a new VR with the new style connector, then figure out which pin should be negative(black) on the female side, take a photo(please) showing which pin should be red and which one black, that would be great. It's almost something that should be in the knowledge vault. I find it hard to believe Buell does point this out in the directions that come with the new connector. Even the HD mechanics wouldn't know any better - at least not the ones I've seen. Thanks again for the effort Rays. I look forward to what you discover. | ||
| Ronmold |
I don't remember but there could have been some directions in the upgrade kit or a wire color indicator on one of the diagrams when I did mine or I would have come up with the same thought. But maybe not, it was almost 2 years ago.  | ||
| Uly_dude |
No, I looked the directions over n over, all 3 pages, not a mention anywhere of positive goes here, negative goes there. So I just marked the cables and picked my spot. I figured I had a 50/50 chance. Though taking apart that new connector may be next to impossible to do without destroying it.  is right. | ||

If I remember correctly the new 77 connector can only be connected one way so since yours is now modified a new VR should just plug right in. | ||
| Ronmold |
Yes, but was it modified correctly? Both sides of the 77 were replaced so it works on that bike but does it match the new VR standard? I could just see it, way out on a long ride and your VR craps out but as luck would have it one of the guys is packing a new replacement unit. You happily do a roadside repair on a hot engine only burning yourself a few times! You fire it up and proceed to blow the new VR and your ECM to the next county. Not a great day.  | ||

OK, my spare regulator does have the new style of '77 Connector fitted. The Deutsch Connector's have each location numbered if you look very closely on the plastic housing on the wire-entry side. Pin 1 goes to negative(black) and pin 2 goes to positive (red). So, looking from the pin side the bottom pin in this view goes to negative.  Just to make that clear I have placed the connector that will be replaced on the loom into the regulator output and placed my multimeter leads into the relative positions for the red and black wires.  | ||

thank-you, thank-you very much! | ||
| Uly_dude |
Thanks Rays. I'll get in the garage tonight to see if I got lucky! If not, it's going to be a bitch to get those two connectors apart. Crossing my fingers... | ||
| Rays |
Actually they only look like they are difficult - no special tools are needed. Step 1. - the orange part you can see in picture #1 above is easily removed with long-nosed pliers. Pull out gently. Step 2. - each pin has a small plastic latch that you can access through the hole vacated by the orange piece. Move this latch aside by about 1/16" while pulling gently on the corresponding wire at the rear of the plug. Step 3. - reassemble in reverse order. | ||

Again, thanks Rays. You've been more than helpful. I did check my new 77 connector last night and as luck would have it, I've got the wires crossed. Guess what I'll be doing this week... | ||
| Ronmold |
Greg, you can't even win on a 50/50 deal, forget the lottery!  | ||
| Uly_dude |
I know I know. But perserverance does pay off, as well as a little help from your friends. I switched the wires around last night. Wasn't as easy as the Ray Beam said it should be, but we got er done. So did you check yours Ron? Did you get the wires right the first time?? | ||

The ride's still buried down in the shed, don't want to wake it up too early from it's hibernation as it would then be hungry for asphalt! I do need a couple weeks tech time before riding season as I need to do a color change to blue, breather reroute, some LED accent lighting (underglow and YES I know it's a Ulysses)! Erik's race ECM, do something with the iron oxide muff (ceramic?) And i'd like to look into '07 springs, and.. hey does it ever end?  | ||
| Uly_dude |
No it doesn't! Check out my profile and the list of things I've done. Most of that was done this winter. And now I'm making a list for next winter; fuel pump R&R, handlebar risers, top case rack, side panniers, front brake rotor from Erik Buell Racing, maybe the Erik Buell Racing ECM, and yes, 07 springs for me to. I know I'm forgetting other items. Ah but the list grows.... |
