Title: 3UR-FBE CHARGING: GENERATOR: INSPECTION; 2015 MY Tundra [08/2014 - ]
INSPECTION
1. INSPECT GENERATOR ROTOR ASSEMBLY
(a) Check the rotor for an open circuit.
(1) Measure the resistance according to the value(s) in the table
below.
Standard Resistance:
100 A Type and 130 A Type
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Slip ring - Slip ring
20°C (68°F)
2.3 to 2.7 Ω
150 A Type
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Slip ring - Slip ring
20°C (68°F)
1.5 to 1.9 Ω
If the result is not as specified, replace the rotor assembly.
(b) Check if the rotor is grounded.
(1) Measure the resistance according to the value(s) in the table
below.
Standard Resistance:
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Slip ring - Rotor
Always
10 kΩ or higher
If the result is not as specified, replace the rotor assembly.
(c) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor assembly.
(d) Using a vernier caliper, measure the slip ring diameter.
Standard diameter:
14.2 to 14.4 mm (0.559 to 0.567 in.)
Minimum diameter:
14.0 mm (0.551 in.)
If the diameter is less than the minimum, replace the rotor
assembly.
