Hi Mike. The 3 wires are covered in a black mesh. I have opened them up and this is what's beneath. Looks like 3 white wires. Just had a look at what it connects to and there are Red, pink, green and yellow wires coming from it.
Theirs a Diode test for the Pink, Yellow and White. (All the White Wires from the Stator)
The Green/Red is Neutral Safety Switch and goes into Wire Harness.
The Pink, Yellow and White (All the White Wires) go to your Regulator/Rectifier converting AC to DC and will charge (or maintain really) the Battery
You can do a bench Diode Stator Test to see and then you can also do a Voltage test while the Bike is running to see what output each wire is giving with your multimeter.
With the Diode Test while not running, you’ll do a Polarity and Reverse polarity test to see your readings
Connect MM (multimeter) to Ground check each white wire, write those numbers down
Connect MM to Power check each white wire, write those numbers down
Should be between 400-500 for diode test
Switch MM to Voltage (20) and connect to Ground, test each wire
You should not get a reading doing this, if you do it could be a break in whichever wire.
The test while running is most accurate and tells you what’s going on with your Stator.
I would see what the battery is doing while running with a multimeter, if it’s maintaining power etc.
Regulators and Rectifiers can be the culprit in these older bikes.
The Multimeter is your friend and will tell you what’s going on with your bike
