Checks to perform:
The motor never runs
To check the wiring, measure
(Ω) between the following wiring
connectors of the main circuit
board (see fig. 4) and compare
them with
the correct ones
(see pag. 47: point 4 - motor
parameters)
- between J11-2 and J11-5,
a value as in point 4 - B (Stator)
must be found
- between J11-1 and J11-5,
where featured, a value
as in point 4 – D must be found
(half field stator).
- between J11-3 and J11-4,
a value as in point 4- C (rotor)
must be found.
