CHECKING THE STARTER MOTOR
•
To carry out the check, power up the
motor with a 12 V 9 AH battery.
•
Win an AC ammeter clamp measure
the steady running absorbed current
(after 5 seconds).
Correct value 50 - 60 A.
CHECKING THE STARTER MOTOR RELAY
•
To check that the relay is operating
correctly:
•
Power the two male terminals (85 - 86)
with a 12 V voltage.
•
Using a tester (in ohmmeter mode)
check the continuity between the other
two terminals (87 - 30).
Correct value with relay energised: 0 Ohm
Correct value with relay not energised: infinite
ohm
•
If the values do not correspond to those
indicated, replace the relay.
