You say resistor wire? Do you mean the diode on the wire from the stator/chraging coil?
The diode is the recifier that changes the AC voltage from the stator, to DC volts to charge the battery.
878A w0uld be my thought.
There are no specs on the diode. You can find a diode at electronic supply that would be rated at 15 amps. But I would order the Briggs part number.
Please rate to close.
