There is hope the coil is still functional!  Thanks for clearing that up.

Although I may need to go direct to chassis ground on the blk field coil plug based on the manual diagram.

The green wire on our unit is a pass-through to ground, so you can still hook it up directly to the unit.

Is he wiring in a Honda R/R? Yamaha use Black for ground.

I’m under the impression the entire unit is grounded through the battery negative green and flowing positive (charged) voltage through red after being rectified.

Yup. More or less.

No luck tonight with power to black R/R wire.

Mind bottling really, between whites will go from .1VAC to .5VAC with a little revving.

OK. Next test.

Disconnect the R/R from the stator and double-check that the green wire (the one bundled with the red) is grounded and that the red wire is connected to the battery positive terminal. Verify that these are good connections by reading DC voltage between the red wire and ground (should be around 12.5V) and then measure resistance between the green wire and the battery negative terminal (should be close to zero Ohms).

Now, connect the black wire to the battery positive terminal along with the red and repeat the DC voltage test on the black wire to be sure it has power.

Finally, measure the DC voltage between the white wire and ground. We should have about 12.5V here, too.

Do you want the plug green chassis grounded or to negative battery?

Also, verified there was voltage through loose green and white wires to the stator last night. Going to voltage with the black wire makes every wire powered except the white ones I want and green plug negative.

For the green wire, have it hooked up however you plan to have it once the bike is up and running. Either is technically fine.

How much voltage was on the green and white wires? Unless it was 12V, then we still have a problem to sort out.

Both were static battery voltage.
