414-00-8 Charging System — General Information 414-00-8
DIAGNOSIS AND TESTING (CONTINUED)
PINPOINT TEST C: RADIO INTERFERENCE
CONDITIONS
DETAILS/RESULTS/ACTIONS
C1: DISABLE GENERATOR
1 Remove the auxiliary drive belt.
REFER to
Section 303-05.
2.
3 Run the engine for a few seconds with the
radio turned on.
• Is interference still present?
Yes
REFER to Section 415-00.
No
REPAIR circuit 30-DA2 (RD). TEST the sys-
tem for normal operation. If interference is
still present. INSTALL a new generator.
Component Tests
No-Load Test
1. Turn off all electrical loads and the ignition
switch.
2. Connect the leads of multimeter across the
battery terminals.
3. Read the voltage (base voltage).
4. Start the engine.
5. Run the engine at 1500 rpm with no electrical
load.
6. Read the voltage. The voltage should be in
the range of 14.1 to 15.1 volts. If the voltage
increase is less than 2.5 volts above the
base voltage, perform the load test. If the
7. Voltage increase is greater than 2.5 volts;
perform the generator on-vehicle tests in this
section.
Load Test
1. With the engine running, turn on the air
conditioning unit, turn the blower motor to
high speed and the headlamps to high beam.
2. Increase the engine speed to 2000 rpm. The
voltage should increase a minimum of 0.5
volts above the base voltage. If the voltage
does not increase as specified,
refer to the generator on vehicle tests in this section.
If the voltage increases as specified, the
charging system is charging correctly.
