Checking Functional Members - Robin America RG2800iS Service Manual

4-5) CHECKING FUNCTIONAL MEMBERS

(1) STATOR
Disengage connectors on the wires from stator and check
the resistance between the wires using a circuit tester
referring to the table below.
NOTE : If the circuit tester is not sufficiently accurate, it may not
show the values given and may give erroneous readings.
Erroneous readings will also occur when there is a
wide variation of resistance among coil windings or
when measurement is performed at ambient
temperature different from 20 C (68 F).

4P Connector
(AC Output Wires)
8P Connector
Rectifier Connector
(2) INVERTER UNIT
Check if there is any change of color or blister in the filling resin.
Also check that no change of color or breakage is visible on any electronic component or wire or connector of
the inverter unit.
Check the conductivity between the output wires and the 4P connector as per the tables below:
