TROUBLE SHOOTING
29
10. IMPROPER GENERATOR
CHARGING RATE.
1936-42
a. Generator Does Not Charge or Rate
is Too Low.
( 1 ) Inspect wiring to see that it is prop-
erly connected to the generator, regulator
and ammeter.
( 2) If generator has third brush con-
trol, inspect the fuse (if so equipped) and
the brush setting.
( 3) If charging rate is still unsatisfac-
tory, remove the generator drive belt and
the relay or regulator cover.
( 4) Ground the generator field ter-
minal. Close the circuit breaker contact
points.
( 5) If the generator revolves slowly as
a motor and the ammeter shows a steady dis-
charge of approximately 5 amperes, test and
repair or replace regulator.
( 6) If the generator does not revolve
slowly, or the ammeter reading is unsteady
or not approximately 5 amperes discharge,
replace or repair the generator.
b. Charging Rate Excessive.
( 1) On generators with third brush
control, check third brush setting. If the
condition cannot be corrected by retarding
the third brush, repair generator.
( 2) Make certain generator regulator
is properly grounded (where regulator is
used). Remove wire from generator field
terminal. If excessive charging rate con-
tinues with field wire removed, the field cir-
cuit is grounded in the generator and gener-
ator repairs are necessary. If there is no
charging rate with the field wire removed,
test and repair or replace the regulator.
11. LIGHTS.
1936-42
a. Lights Inoperative.
( 1 ) If the engine cranks and starts,
there will be current in the lighting circuit
at least as far as the ammeter, and light fail-
ure will be caused by switches, wiring har-
ness, lights or bulbs. ·
( 2 ) If all lights are inop•erative, inspect
the fuse (see "Data and Specifications" chart
on page 148 for location), and the wire from
ammeter to lighting switch.
( 3) . If current is delivered to the switch
but not to the wiring harness, replace the
lighting switch.
( 4) If only one light is inoperative, in-
spect the bulb and wire at the light.
( 5) If the bulb is good and there is no
current to the lights, be sure the light is
properly grounded.
( 6) If there is no current at the end of
the wire connected to the light, inspect the
connectors and connections at the terminal
blocks.
( 7)
If
both headlights fail, inspect the
dimmer switch.
· ( 8) If stop light only fails, inspect con-
nections and test stop light switch.
( 9) Replace or repair the wiring har-
ness if trouble is not located by the above
procedure.
b. Light Bulbs Burn Out Frequently.
( 1) Inspect connections at generator,
ammeter and battery and clean and tighten.
( 2) Inspect battery terminals and·
clean and tighten.
( 3) Inspect and clean ground connec-
tion for bulb.
( 4) Inspect generator regulator and
adjust if necessary.
12. IMPROPER CLUTCH OPERATION.
1936-42
( 1) If the clutch slips when the pedal
is fully released, check the pedal free play
and adjust if necessary.
( 2) If the clutch slips with the correct
free play, or if it grabs or chatters, remove
the clutch assembly for inspection and re-
pairs.
