Symptom: Battery does not charge
Resistance is less than standard.
Charging coil is shorted.
Set multimeter on 0V~20V DC voltage, measure the
voltage between connector to the battery wire terminal
(usually a red or red/white wire) and the ground.
No voltage display
Wire from connector to
battery is broken.
Diagnosis procedures
Battery does not charge
Disconnect connectors of magneto lead wire tied to the cables of the whole motorcycle.
Measure with an Ohmmeter between out-put wires from charging coil
Resistance meets the standard.
Connect connectors of magneto lead wire harness to the
cables of the whole motorcycle; break off connectors of rectifier
or regulator to cables of the whole vehicle.
Measure with an Ohmmeter on the resistance in the connectors
between output wires from charging coil, and check if the result
is in accordance with the resistance of the charging coil itself.
Yes
