Is my Electrosport Stator Defective?

Update from yesterday evening:

1. Plugged relay 2 back in. Battery terminals read 12.7 key off, 12.6 key on, 13.0 when I took it off the tender about an hour ago.
2.

Have been hanging out here since February - trying to learn stuff - when I bought a nice low mileage 2001 V11S. Rode 6K fun miles between then and August, with no drama, and then the charging system started acting up: first overcharging and destroying a new Odyssey battery . . .

 

Let's talk batteries, @Sam P.

Did you replace the "destroyed Odyssey" with another Odyssey, or something else?

A voltage loss from 13.0 to 12.7 in an hour is not a good sign for an Odyssey. There are specific parameters to "condition" the Odyssey that may help contribute to a solution. "trickle chargers"/ "tender" are known to be damaging to the Odyssey battery unless the voltage is adequate, yet will not "charge" the Odyssey with sufficient amperage (at least 6 amps).

SamP , did you reconnect the red/green wire to the V reg ? 

Also , there should be continuity between the 2 pin connector consisting of a blue wire and a red/black on the regulator wiring harness of the bike wiring harness.

HEY HEY HEY . I'm not smart enuf to do that !

Mostly for helping myself to understand the circuit and the suggestions for troubleshooting, might be of help to others. If someone sees errors, I will correct them.

Mea culpa: I just realised I didn't do the math to the end here

I've corrected myself there, and here

Nicely simplified schematic.

Just a note, that the red/black output from "Headlight" Relay (#2) does supply the brake light (also horns), but not the entire left switch cluster (i.e.: not the turn signals).

Perhaps Fuse #5 (F5) should be indicated ahead of the Starter Relay. Turn signals are Fuse #7 (F7)

good suggestion, I will pour some Evan Williams and make some changes

Looking at this simplified diagram , you should be able to disconnect the two wire connector (blue wire & red/black wires) and apply 12v and - to these two wires and the gen light turn on. This will test the bulb and wiring circuit.
