Re: Voltage regulator
There are ways to test that it charges to it's rating. Those are a bit complicated to run. To test that it charges, measure the voltage on the battery, motor not running. Now start her up on flusher and measure voltage again. If it is higher VR is charging. Alternatively attach some kind of load to battery to drop voltage and then rev motor and see if voltage jumps back up. You can use an auto headlight, boom box, most any 12VDC device.
