Baja F4-2.5L SOHC (2003)
Alternator: Testing and Inspection
INSPECTION
DIODE
CAUTION: Never use a mega tester (measuring use for high voltage) or any other similar measure for this test; otherwise, the diodes may be damaged.
1. Checking positive diode
Check for continuity between the diode lead and positive side heat sink. The positive diode is in good condition if resistance is 1 Ohm or less only
in the direction from the diode lead to heat sink.
2. Checking negative diode
Check for continuity between the negative side heat sink and diode lead. The negative diode is in good condition if resistance is 1 Ohm or less
only in the direction from the heat sink to diode lead.
ROTOR
1. Slip ring surface
Inspect the slip rings for contamination or any roughness of the sliding surface. Repair the slip ring surface using a lathe or sand paper.
2. Slip ring outer diameter
Measure the slip ring outer diameter. If the slip ring is worn replace rotor assembly.
Slip ring outer diameter:
Standard 22.7 mm (0.894 in)
Limit 22.1 mm (0.870 in)
