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. 67).

H35, HS & HSSK 40-50, HM & HMSK 70-80-

100

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. 68).

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.
