Rectifier Test
16. Check for continuity in each direction' between the
B terminal and P terminals, and between the E
t e r m i n a l a n d P t e r m i n a l s o f e a c h d i o d e p a i r '
All diodes should have continuity in only one
direction. Because the rectifier diodes are designed
to atlow current to pass in one direction, and the
rectifier is made up of eight diodes (four pairs), you
must test each diode in both directions for
continuity with an ohmmeter that has diode
checking capability: a total of 16 checks.
. lf any diode is faulty, replace the rectifier

. lf all the diodes are OK, go to step 17.

Alternator Brush InsPection
17. Measure the length of both brushes (A)with a
v e r n i e r c a l i p e r ( B ) .
. lf either brush is shorterthan the service limit,
replace the brush assemblY
. lf brush length is OK, go to steP 18.
Alternator Brush Length:
Standard {New): 10.5 mm {0.41 in.)
Service Limit:
1.5 mm (0.06 in.)
Rotor Slip Ring test
18. Check that there is continuity between the slip rings
( A ) .
. lfthere is continuity, go to step 19.
. lf there is no continuity, replace the alternator'
Check that there is no continuity between each slip
ring and the rotor {B) and the rotor shaft (C).
. lf there is no continuity, go to step 20
. lf there is coniinuity, replace the alternator.
