350 Milliamp Charging System
CHECKING THE SYSTEM: The battery must be in the
circuit to perform the test properly. Set the voltmeter to
the 0-20 D.C. volt scale. Connect a voltmeter across
the battery. The voltmeter should read battery voltage.
Start the engine. With the engine running, there should
be an increase in the voltage reading. If there is no
change in the voltage reading, the alternator is defective
and should be replaced (diag. 94).
18 Watt A.C. Lighting Alternator
Models: H35, HS & HSSK 40-50, LH195, HM & HMSK
70-80-100, LH318, LH358
CHECKING THE SYSTEM: To check the system,
disconnect the plug from the rest of the lighting system.
Connect a wire lead from the single pin connector
coming out of the engine to one terminal of a No. 4414,
18 watt bulb. Connect another wire to the remaining
terminal of the bulb and run it to a good ground on the
engine. Start the engine and test the circuit using the
A.C. voltmeter as shown (diag. 95).
With the engine running the minimum A.C. voltage
across the bulb should be:
2000 R.P.M. - 6.0 Volts A.C.
3000 R.P.M. - 8.5 Volts A.C.
3600 R.P.M. - 10.0 Volts A.C.
If minimum values are noted, the alternator is okay. If less
than the minimum values, the alternator is defective.
35 Watt A.C.
Before making any exterior tests, check for an inoperative
switch, shorted wires and burned out headlight and/or
stop tail light. To check out the alternator, check the
A.C. lead to ground at each yellow wire (diag. 96).
With engine running, minimum values should read:
2500 R.P.M. - 8.0 Volts A.C.
3000 R.P.M. - 9.5 Volts A.C.
3300 R.P.M. - 10.5 Volts A.C.
3600 R.P.M. - 11.5 Volts A.C.
If the above minimum readings are noted, the alternator
is okay. Check for defective lights, wiring or switches.
If less than the above readings, the alternator is
defective.
NOTE
On older point ignition systems, the A.C. output leads
are black and red.
