Do the checks I mentioned above and let us know what you find.

Couldn't find anything wrong. Took it out for a test ride, got about 10 minutes in and the check engine light was back on and the bike started running rough. When I stopped, the bike was dead again. Put a meter across the battery and get about 12.4 V. The three things that I think it could be are battery, voltage regulator, or stator. Anyone know of a likely candidate?

Thanks.

Sounds to me like you are right, it could be the battery, regulator, or stator, or any number of other electrical gremlins, but applying the electrical troubleshooting procedures in the service manual should tell you exactly what is wrong. It's really hard to evaluate electrical issues over the internet, your results from charging the battery basically narrows it down to the three main possibilities you already mentioned. The battery is easiest to check, I would start there.

Thanks all for the tips. Should have warm enough weather to get in the garage and step through everything you all mentioned. I'll repost as soon as I get through it all.

Voltage Regulator Problem Solved

Thanks for all of you good ideas . . . everything looked good till I got to the battery. Across the terminals I was showing almost 13 Volts, but on the pigtail for the Battery Tender I had dropped to 9 volts. When I saw this difference, I checked my connections more closely, sure enough the negative was loose. Passed the initial test, so I think we might be good.

Thanks everyone!

Someday hopefully I;ll get to meet you all.
