Higher Voltage
If voltage is higher than standard value, check ground of brushes.
If brushes are not grounded, replace IC regulator.
Lower Voltage
If voltage is below or in standard value, increase engine speed up
to 2000 – 2500 rpm soon after starting engine with all electrical
loads on, and read maximum value on ammeter immediately.
If current is less than 49 A, repair or replace generator.

OVERCHARGED BATTERY
1) To determine battery condition, refer to Battery section.
2) If obvious overcharge condition exists as evidenced by exces-
sive spewing of electrolyte, measure generator B terminal volt-
age at engine 2000 rpm.
3) If measured voltage is higher than upper limit value, proceed to
disassembly section of generator service.
4) Check ground of brushes. If brushes are not grounded, replace
IC regulator. Then check field coil for grounds and shorts, refer-
ring to “INSPECTION” section.
