11.8V at idle 14.8V at 3000 rpm on RR side, 13.4V on batt side approx 200mV bounces between 140 and 300 mV - approximately, never settles on a number. Yes, checked that early in the process when I was also checking solenoid and battery cable connections

Didn't do red to black at the plug, but red on RR side to neg batt post. Should I check red to black at RR plug, on RR side? Sent from my iPhone using Tapatalk

13,2V at idle Sent from my iPhone using Tapatalk

Red to ground, or neg batt cable? Sent from my iPhone using Tapatalk

AC right? I just checked at idle and 3000 rpm about 11.8 V on any given pair of leads, from the back of the connector Cleaned that one early on, looked great, cleaned and greased anyway.

It seems like a bad connection somewhere, especially considering the tach behavior. I recall that after I took off around the 8 minute mark, I was cruising at a constant speed when the tach got really erratic around 8:30ish. Sent from my iPhone using Tapatalk

I've got a replacement eBay regulator on there now, put on about 2 weeks ago. That battery charger was only putting out 13.8V with the meter hooked directly to it, not on the battery. I have yet to find a connector with any discoloration. Most contacts so far look fine, but I clean and grease them anyway. I don't know if anyone with a first Gen, except for a guy selling one about 2 hrs from me. Sent from my iPhone using Tapatalk

see this youtube link I apologize for the shakiness of the video. I fashioned a makeshift mount and attached a FlipCam. You can still make out the important parts. Here's a list of time stamps if you want to hurry through to the "good stuff" :30 - :41 erratic behavior during initial acceleration getting out of the parking lot at work :50 a little jumpy 1:22 a little jumpy 1:47 stop at a stop sign, see my voltage drop to 10V 2:42 erratic 3:30 7:50 a little jumpy 8:00 stopped at an intersection, voltage dropped to 10V 8:16 tach takes a dip 8:30 - 9:00 the tach is pretty darn goofy 9:16 - 9:36 tach is erratic again 10:12 stop again, voltage drops to 10V 10:35 tach is stupid again briefly

Thanks for the info Randy. I actually did what you suggest. I checked them all, bought the 13 I needed an then went back in for the replacement process. I think I "pocket posted" from my phone earlier. 😄 Sent from my iPhone using Tapatalk

13.7V when I checked it at 8 am right after I took off the charger. Not bad since my charger was only putting out about that much. I checked it 4 hrs later and it's at 12.9V. I rechecked the stator to neg batt cable and I still show "open". Sent from my iPhone using Tapatalk

Don't think so. Will do that In the am Sent from my iPhone using Tapatalk

1) my 2A charger is only putting out 13.7V. I just put it on the battery and will leave it all night. I'll check the voltage on the battery in the morning. If it's not high enough I guess I could put my 10A charger on it for a little while and see if it will bring it on up. 2) connections are fine. No discoloration at all 3) already swapped it with an eBay unit since all this started. I have measured stator to ground with a couple meters. Always shows open connection.

It does seem like a charging problem although several opinions are that my stator is ok based on the tests described, although my AC voltage measures at the stator plug is low. So yes, a potential charging problem. I also have the intermittent hiccup/sputter/misfire thing going on, which can be seen in the tach along with some other erratic behavior of the tach (not smooth during a lot of slow to midrange acceleration. Don't know if charging symptoms are related or not. In the meantime I continue to drive it since it's not too bad, maybe slightly improving. Today was a pretty good drivability day. Not to say it didn't cut up, but it was relatively minor. Sent from my iPhone using Tapatalk

No. And hardly any increase at 3000 rpm Sent from my iPhone using Tapatalk

12.46V Sent from my iPhone using Tapatalk

First I did it wrong, then re-tested. read below. Idling voltage across battery: 12.4V 3000 rpm voltage across battery: 12.7V Idling signal fuse voltage: 11.7 on each side of fuse at crimp applied brake and let go: voltage is 10.8V on each side of fuse at crimp At idle i saw the voltmeter dip when applying the brake (hand or foot). I go back out within 5 minutes and test it the way you told me. Idling voltage on each side of fuse at crimp: 11.0V Idling voltage with brake lever applied: left side of fuse at crimp 9.8V, right side of fuse at crimp 9.5V. repeated that test and saw the 0.3V difference again between left and right side of fuse.

It dropped to 10V, right between green and yellow on every stop (2 or 3) on my way to work. I may go run around a bit on my lunch break and see what it's doing. Not sure what's happening. As you may recall from earlier posts, my stator seems ok in every respect except for AC voltage output at 3000 rpm. Several posts on stator testing mention gettine 50-100 VAC, and mine was only 47-48V, although all legs were equal, and no shorting to ground, resistance reading within spece between the wires, etc.

I bought a 2nd gen starter (used) for $40 +shipping. Any year 2nd gen will be a 4 brush starter, from all the info I've read. Sent from my iPhone using Tapatalk

I've ridden my bike everyday except Wednesday this week, only because I needed my car that day. I recorded some video if the tach and voltmeter , but haven't been able I upload it yet. Observations of the voltmeter: starts off around 12V, will reach 14V on the highway, but will also drop to about 10V when I stop at an intersection. Will come back up to 12V when i take off and may or may not get back up to 14V in the next several miles. I can't say at this point that the voltmeter behavior is necessarily correlated to the erratic "misfire" issue. I'll repost when I can get something on YouTube, which I can't do at work. I also used Jeff's led indicator idea on the red/white wire at the TCI and it never once blinked at me. Still hooked up since Wednesday morning. I haven't done the led on black/white wire yet.

Just to clarify, the voltmeter isn't really "jumpy" with the tach, but will ride at different voltage levels during the ride. Sent from my iPhone using Tapatalk

In dash (factory) voltmeter, and it's a guess at 13.5, although i know i've seen it squarely between 12 and 16 at times (14V? I assume). As far as i know, i've disconnected and cleaned every connection related to charging and ignition circuits. I can certainly look again, or re-clean or whatever. Suggestion for where to start again?

The ride home was pretty rough after a while, not sure when it started, but over halfway home in my 40 minute commute, it started missing pretty often and drivability (enjoyment) was gone. i didn't have time to do anything with it yesterday, but i did clean the stop/run switch. As with most all connections i've cleaned lately, it looked great before i started, but i hit the contacts with a brass brush and the contact cleaner. I take off this morning and everything is going well (maybe a hiccup or two for a while, nothing major) until about 25 minutes into my ride. I'm running about 3800-4000rpm at 70-75mph indicated. It starts to feel like someone is yanking on the back of the bike. Before, i can kinda "sense" the "misfire" now i can definitely feel it and I think other drivers can probably see it. I seriously wondered if it was going to just shut down completely. The tach is swinging much more wildly when this happens, approximately up to 1500 rpms swings, generally 300-100 rpm swings during this time. I would never try to drive it like this if it were continual. When i slowed down and took the exit (had to stop to take the next road) It didn't exhibit this crazy behavior again. i probably didn't get over 3000 rpm and 50 mph the rest of the way to work (3 mi). I also notice throughout the ride that sometimes my voltmeter shows 13.5 V and sometimes 12V. I'll run out at noon and get the LEDs and see what story they may tell. I look forward to trying this. I also have a guy at work bringing me a GoPro camera today. I'll try to get that mounted up and post some YouTube video links. I think it will help for you guys to see the tach behavior.

I'll have to give this a try.

Did that this weekend: cleaned and greased.
