6D3-6 STARTING AND CHARGING SYSTEM
Continuity of Contacts
With the plunger faced downward, push down the magnetic
switch. In this state, check for continuity between terminals B
and M. Replace, if there is no continuity (i.e., contacts are
faulty).
Pinion
Check if the pinion rotates smoothly in drive direction by hand,
or if it is locked when it is rotated in reverse. If not, replace the
pinion.
Characteristic Test
For easily confirming the characteristics, conduct the noload
test as follows:
Rating as short as 30 seconds requires rapid testing.
Fix the starter on the test bench, and wire as shown in
illustration. When the switch is closed, the current flows and
the starter runs under no load. At this time, measure current,
voltage and speed to check if they satisfy the standard.
