input test.
Normally.open type:

1. Check for continuitv between the terminals.
. There should be continuity between the A and B
terminals when power and ground are connect-
ed to the C and D terminals.
. There should be no continuity between the A
and B terminals when power is disconnected.

Rectifier Removal
MITSUBISHI:
1. Remove the four through bolts.
3.Separate the rear housing from the drive-end hous-
ing by inserting a flat tip screwdriver into the open-
ings and prying them a part. Be careful not to dam-
age the stator with the tip of the screwdriver.
Separate the rear housing and drive-end
with the stator anached to the rear housinq.
n ousrng
2.Heat the rear bearing seat with a 1,000 W hair drier
for about five minutes (120 - 140'F, 50 - 60'C).

Reetifier Removal (cont'd)
MITSUBISHI:
5. Separate the rear housing from the stator/rectifier
assembly by removing the four screws and the ter-
minal nut.
6.
1.
Unsolder the rectifier from the stator leads.
. To avoid damaging the diodes with heat, pinch
the stator leads between pliers to carry heat off,
and apply the soldering iron only long enough to
separate the leads from the rectifier.
. Use a 100 W soldering iron.
Installthe new rectifier in the reverse order of removal.
. Apply the soldering iron only long enough to
ensure a good connection so the heat will not
damage the diodes.
. Use only a rgsin core type solder or solder joints
will cor.ode.
RectifierTest
NOTE: The diodes are designed to allow current to pass
in one direction while blocking it in the opposite direc-
tion. Since the alternator rectifier is made up of nine
diodes, each diode must be tested for continuity in both
directions with an ohmmeter that has diode checkino
capability; a total of 22 checks.
1. Check for continuity in each direction between- the B and P terminals.- the B' and P terminals,- E (ground) and the P terminals.
All diodes should have continuity in only one direc-
uon.
2.lf any of the diodes fails, replace the rectifier assem-
bly. (Diodes are not available separately.)

Rotor Slip Ring TestAlternator Brush Inspection
Separate the drive-end housing from the rear hous-
ing as described on page 23-l 1 1.
Separate the rear housing from the stator/rectifier
assembly by removing the four screws and the ter-
minal nut from the rear housing (see page 23-111).
Measure the length of the brushes with vernier
calrpers.
Alternator Brush Length:
O Standard (NEW)O Service Limit
19.0 mm (0.75 in)5.0 mm (0.20 in)
lf the brushes are less than the service limit, replace
them.

MITSUBISHI:
1. Checkthe resistance between the slip rings.
There should be 1.8 - 3.0 ohms.
. lf resistance meets the specification, go to step 2,
. lf resistance does not meet the specification,
replace the alternator.
SLIP RII{GS
Check that there is no continuity between the slip
rings and the rotor or rotor shaft.
lf the rotor fails either continuity check, replace the
alternator.
Stator Test
1. Check that there is continuity between each pair of
leads.
co|LconE
Check that there is no continuity between each
and the coil core.
lf the coil core fails either continuity check, replace
the alternator.

Rear Bearing ReplacementAlternator Reassembly
MITSUBISHI:
1. Pull off the rear bearing.
Make sure the tips of the bearing puller jaws are
thin enough to fit between the bearing and the
slip rings.
Do not reuse the bearing.
BEARING PULITRSLIPRINGS (Commorciallyav6ilable)
Use a hand press to install the new bearing. Applypressure only on the inner race to avoid damaging
the bearing.

REAR BEARING
1.Push the brushes in, then insert a pin or drill bit(about 1.8 mm diameter)to hold them there.
ARUSHES
Heat the rear bearing seat in the rear housing as
described on page 23-12. After heating, continue
immediately with assembling before the rear bear-ing seat cools completely.
Put the rear housing/stator assembly and drive-end
housing/rotor assembly together, tighten the four
through bolts and pull out the pin.
