GY6 Rectifier Pin Testing By Bashan (Read 21,376 times)

Let's go over the standard pin out chart and how it relates to testing the pins.

Ok actually this diagrams is easy to read.
Top Left corner is your multi meter. Plus is your Red wire Minus is your black wire.

Now the rest of the chars show that if you touch the Yellow which is the top left connector with your Red Lead on your MM to say the Green which is the bottom Right connector with the Black lead of your MM you should get a reading on your Meter that is between 5K and 100K ohms. I should have stated you need to set your meter to measure Resistance (ohms)

And so on the top bar is where to put the positive lead from MM
left side bar is where you should put your Black Negitive lead from your MM. the rest is the readings you should get.

The reading you should get for say White (+Lead) to Yellow (- lead) should be INFINITY or show as 0 resitance some meters show and NA

This old diagram is not universal, but the concepts (not the values) apply, meaning AC voltage in on one pin (from stator) grounded by the GREEN wire, outputs are 1. Battery charging DC on the RED wire 2. Headlight AC voltage on YELLOW.
I had a stack of NEW rectifiers of different manufacture and price but all were for the same application. Using the Ohm meter, the numbers were all over the chart, like Meg-Ohms (100,000 ohm) not K-Ohm (1,000 ohm) as described in the manual, but all worked. Internally they were designed differently so the ohming from pin-to-pin method does not apply.

And this appears to be the wire to pin configuration on most modern rectifiers:

how about stactor ohms resistans and the magneto
