In case the generated current value is lower than 10A, repeat the test using a new regulator and/stator
alternatively.
Choke Inspection
With the connector connected to the system,
check if there is voltage in both battery terminals
while the engine is running.
If voltage is detected, replace the automatic starter
as it is surely failing.
If no voltage is detected, connect the multimeter
negative terminal to the earth terminal and the
positive terminal to the automatic starter orange
cable; with the key switch set to «ON» and the en-
gine emergency cut-off switch set to RUN, check
there is voltage in the battery; If there is no voltage,
check the wiring connections to the key switch and
that fuse No.1 works properly.
If there is voltage, check again the ignition control
unit connector. After disconnecting the starter,
start up the engine and keep it at idle speed and
check there is voltage when the multimeter posi-
tive terminal is connected to terminal No. 8 (Red/
Blue) and the negative one to terminal No. 11
(White/Red).
Replace the control unit if there is no voltage; oth-
erwise, check the wiring connections between the
starter and the control unit.
