GENERAL
The charging system for 3-cylinder (Suzuki 660)
gasoline and Perkins diesel engines consist of a 55
amp alternator.
Perform the following tests to determine if the alterna-
tor is faulty.
OUTPUT CURRENT TEST
(See Figure 10E-1)
1. Remove the RED wire from terminal B of the
alternator.
2. Set multimeter to 20 VDC range. Connect POS
(+) test lead to terminal B and NEG (–) test lead
to ground.
3. Reconnect battery NEG (–) cable.
4. Start the engine.
•
As engine RPM increases, voltage should in-
crease to 14 to 14.5 volts. Current output should
increase to a maximum of 55 amps.
NOTE
Charge condition of battery will affect current
(amp) output.
•
As the battery begins to charge, the current out-
put will slowly decrease.
•
If NO voltage and/or current is measured, pro-
ceed with Step 5.
•
If voltage and current does not start coming down
after a short running period, battery is faulty.
