18 EC300 Battery not charging

[Tech]

**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.

The battery needs to be charged from the Stator.The Diode Module ensures the stator can only flow voltage into the Battery circuit but the battery cannot feed back into the Stator circuit (lights etc).
If you diode Module was missing your battery would not charge which is your Problem.
As for running the motor without the battery can destroy your electronics through over voltage.The battery is ,as well as being a load it acts like a regulator

I am at my wits end...& my wits are old & weak!!

Thanks everyone!!
