1J-12 Charging System:
• Using an ohmmeter (1), check that there is no continuity between slip ring (2) and rotor core (3). If there is
continuity, replace the rotor.
• Check slip rings for roughness or scoring. If rough or scored, replace the rotor.
Stator
• Using an ohmmeter (1), check all leads (2) for
continuity. If there is no continuity, replace the stator.
• Using an ohmmeter (1), check that there is no
continuity between coil leads (2) and stator core (3). If
there is continuity, replace the stator.
Brush and Brush Holder
Check each brush (1) for wear by measuring its length
as shown. If brush is found worn down to service limit,
replace brush.
Exposed brush length “a”
Standard: 16 mm (0.63 in.)
: Limit: 5.0 mm (0.20 in.)
Rectifier
Using ohmmeter, check continuity between “B” terminal
(1) or “E” terminal (2) and each diode lead (3).
Check both directions by reversing probes of ohmmeter
and there should be only one-way continuity in each
case. If check result is not satisfactory, replace rectifier
(4).
