18 EC300 Battery not charging FIXED
**Regulator/Rectifier is putting out DC voltage...rising & falling w/throttle
**Relay functioning correctly **Motor & starter running perfectly **Battery..new AntiGravity 8 cell small case..... runs down after each ride...I sometimes have to kick start. Last ride battery was at 8.6 volts at end of ride. Possible causes yet to be verified: #1 Diode at relay - Below is a quote from an old thread indicating it could be the diode attached to the relay. #2 Loose/faulty connection - I have traced most connections but could have missed something.

Thanks everyone!! |

Have not tested the diode. Not sure how to do this.
I have a Fluke 88V meter. Also, I am having trouble reading the wiring schematic. I do not understand how the Battery/Relay/Starter schematic interfaces with the rest of the wiring schematic. |
Diode Test Video
Caution I saw this video on youtube about testing diodes but I don't know anything about this process, so be careful and use at your own risk.

More testing @ diode....view "J" on wiring schematic
**Varying DC voltage on Red wire while bike is running..14.3 max **Static DC voltage on Red/Yellow wire while bike is running & not running. Same voltage as + - on battery. **No readings on White/Black or Green/Yellow wires while bike is running or not running |
Moto7man thanks for the compliment, but I'm not versed on the newer bikes. All I have is the '18 wiring diagram in the owner's manual. It is severely lacking in details. Does not show the stator. Does not show a diode module.
The only diodes I am aware of on the older bikes, are the ones in the voltage rectifier/regulator. The bikes have an AC powered CDI. I'm super busy right now with no time to investigate. I don't know where to get a proper wiring diagram. The red wire voltage at 14.3 sounds good. |

Diagrams too large to download.
