Is my Electrosport Stator Defective?

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).

I replaced the blistered and bloated Odyssey last month with a new one, just before I started this thread.  I've skimmed through your Odyssey Battery Conditioning thread (20+ pages!) and have ordered what I believe is an appropriate charger.(Battery Minder 128CEC2, which I believe replaces the older 12248 model). Will condition my battery asap, but I assume I can continue to troubleshoot my charging issues in the meantime. I am still keeping the battery on my trickle charger, which keeps the volts at 13-13.4, and I hope this isn't hurting the battery.

Good call on getting the approved charger.

Odyssey states that float voltage below 13.2v will shorten battery life. What is your trickle charger's voltage?

How about running a jumper wire from the battery positive to the black wire into the regulator  (turn the connector 90 degrees to leave the white->blue connected). KOEO: battery light on? Start up and normal charging at some rpm with no 4000 rpm light?

No battery light with a jumper wire from battery + attached, key on engine off......

Did you start it to see if it charges with the jumper wire to the black wire of the regulator?

Next, I would jumper the other side of the connector (battery voltage to the white wire and the connector rotated to connect the black --> red/black.

I don't think the light will come on at all in that configuration. Looking for the charging voltage to come up while running above idle. . .

12v/1.25 Amp

Did not start it up. I will do this tomorrow morning and report back. Need to get some better terminal connections for the jumper wire if I am going to fire up the motor.

With ohm meter set at 200, I got 15 ohms, between the blue wire and the center terminal pictured below. What does this mean? I know it's very basic but my electrical knowledge is poor.

(If you meant by "center terminal" the terminal centered below my arrow, the resistance there was zero).

I get 15.9Ω with this same test.

With the trickle charger connected to the battery, test the voltage across the battery terminals (charge voltage).

Most common "trickle chargers" will be below Odyssey's 13.2v minimum threshold.

Haven't bread each response, on the road- but *any* wire circuit should show very near zero ohms. If the lamps are in this circuit, maybe ok. If not, a serious fault. 

The bulb is in this circuit. IDK what r value is for the bulb , BUT i am happy.

Just did this with key on/engine off, and the battery light did indeed light up.

Are we making some progress here? I hope so!

The red/green wire that had a wire nut at the end , did you connect it to anything ?

Pretty sure @Sam P posted the answer to this on page 8 . . .

Yesterday I checked and cleaned all the battery connections and they are good. My F3 is now bypassed with a new 10AWG wire - with inline 30A fuse - from battery + to the two red wires at the regulator.

Just went out to the garage - the DMM reads 13.12v with the Battery Tender attached.

Close but no cigar?
