diode(s) in
rectifier
A. Faulty regulator winding
A. Faulty regulator winding
8. Defective regulator
TEST AND CORRECTIVE ACTION
A.
Remove four input leads from Rectifier
-
Regulator.
Check resistance on
RX1 scale
of Ohmmeter.
Replace stator
if readings not
at test values. Test with engine stopped
Test 1
- Connect Ohmmeter leads to 2 red
leads - about 2.0 ohms resistance shorn be
m.
Test 2 - Connect Ohmmeter leads to 2 black
leads - about g ohms should be noted.
-
B. With engine stopped, connect leads of flash -
light type continuity tester between BAT - NEG
and one of the AC terminals then reverse
these leads
- - lamp should turn ON one way and
OFF the other. Repeat procedure on the other
-
AC terminal.
If lamp indication is the same
both ways, diode is faulty.
A. Remove red lead from
" REG. " terminal on
Rectifier
- Regulator.
Start engine and
operate at full speed. With regulator
wind-
ing disconnected, alternator should charge
at full output. Replace stator
if full out -
put of at least 30 amps is not attained.
A.
Remove
2 red leads from Rectifier - Regula -
tor -- connect these two leads together then
start engine and operate at full speed. A
maximum
4 amp charge should be noted if sta -
tor is OK.
B.
If stator checks out, trouble is in regulator
portion of Rectifier
- Regulator.
Replace
unit.
