Friends, help. Iv got an '07 xb12stt. 20k miles. After my battery died, I bought a new one. It died too. Thinking I ruined it in the new-battery-charging-process, I took them both to Kragan. They tested both batteries ("good") and said "the bike IS giving the right charge back to the battery". What can I check with a basic electrical meter? Or am I just gonna have to pay "Hundred-Davidson"? Any ideas are welcome. Thanks | ||

Do a search on here for "77 Connector", that is likely your culprit. | ||

After I replaced my 77 connector, thinking that was the issue, I then ran the electrical test for the stator and found it to be a fried (broken) stator. The primary oil smelled terrible (give away) upon inspection of the primary area.

Rhino, what you can do with a basic multimeter is set it to read battery voltage, approx 12 VDC. Then start the bike and put the meter leads on the battery posts. While reading the volts DC, raise the rpms to about 2k to 3k. The voltage indication should rise to approx 14 VDC. If the volts do not rise as indicated above, that's symptomatic of charging system failure. If the volts barely rise above static battery level with rpms at 2 - 3k rpms, there could be problems with the charging system that would need further checking out to resolve. Those troubleshooting steps involve checking stator resistance (less than 1 ohm) between the wires of the stator, checking for infinity isolation between each stator wire and engine ground, and conducting an AC voltage test on the stator wires with the engine running. That's just for starters. Then there are isolation checks on the voltage regulator, but we're getting ahead of ourselves at this point. If you're still interested, post up what you find. |
