TROUBLESHOOTING ELECTRICAL CHARGING CIRCUIT FLOW CHART
Check wiring, switches, or
ammeter for breaks or
shorts.
Alternator coil
failure, replace
coil assy.
Identify the charging system
used by model and specification
number or visually checking the
electrical plug.
Consult the Technician's
Handbook or electrical
troubleshooting booklet for
test procedure for the
charging system used.
Test for either AC or DC voltage
as directed at the proper engine
RPM.
Is the voltage greater than or
equal to the minimum value?
