STATOR WINDING CHECK
Specification Desc./Quantity
1 1) Black cable and earth ~ 1
Ω
Ignition circuit
All the control operations of the system that require
the disconnection of cables (checks of the con-
nections and the devices making up the ignition
circuit) must be done with the engine off: if this is
not done, the controls might be irreparably dam-
aged.
Stator check
- Using a tester, check the resistance between the
brown-earth and black-earth terminal.
N.B.
VALUES ARE STATED AT AMBIENT TEMPERATURE. A
CHECK WITH THE STATOR AT OPERATING TEMPERA-
TURE LEADS TO VALUES HIGHER THAN THOSE STATED.
