Field Frame (Field Coil)

Field Frame (Field Coil)

Field Frame (3RZ-FE):

1. INSPECT FIELD COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.

1.4 kW (5VZ-FE):

2. 1.4 kW type:
INSPECT THAT FIELD COIL IS NOT GROUNDED
Using an ohmmeter, check that there is no continuity between the field coil end and field frame.
If there is continuity, repair or replace the field frame.







3. 1.8kW type:
INSPECT SHUNT COIL FOR RESISTANCE
Using an ohmmeter, check that the resistance between the shunt terminal (A) and shunt terminal (B).

Standard Resistance:
At 20 °C: 1.4 - 1.9 Ohms

If the resistance is not as specified, repair or replace the field frame.
