REGULATOR CASE TEMP. (_C)
Higher Voltage
If voltage is higher than standard value, check ground of brushes.
If brushes are not grounded, replace generator.
Lower Voltage
If voltage is lower than standard value, replace generator.
LOAD CHECK
1) Run engine at 2,000 rpm and turn on head light and heater mo-
tor.
2) Measure current and if it is less than 20 A, 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 2,000 rpm.
3) If measured voltage is higher than upper limit value replace gen-
erator.
