1 Amp (18 Watt) Add-on Alternator
CHECKING THE SYSTEM: To check the system,
disconnect the plug from the rest of the lighting system.
Connect a No. 4414, 18 watt bulb in line with each
terminal in the plug. Start the engine and test the circuit
using a voltmeter as shown (diag. 97).
With the engine running the minimum A.C. voltage
values across the bulb should be:
2000 R.P.M. - 8.0 Volts A.C.
3000 R.P.M. - 10.5 Volts A.C.
3600 R.P.M. - 12.0 Volts A.C.
If minimum values are noted, the alternator is okay. If
the minimum values are not noted, the alternator or
A.C. connector is defective.
2.5 Amp D.C., 35 Watt Lighting
If output is below standard listed, pull back protective
coating in front of the diode and check A.C. output. If
A.C. is good check each diode it services as required
(diag. 98).
D.C. value (+) or (-); check both sides of A.C. outputs.
R.P.M. Volts D.C. R.P.M. Volts A.C.
2500 - 8.0 Volts D.C. 2500 - 18.0 Volts A.C.
3000 - 9.5 Volts D.C. 3000 - 22.0 Volts A.C.
3300 - 10.5 Volts D.C. 3600 - 26.0 Volts A.C.
3600 - 11.5 Volts D.C.
NOTE
These minimum numbers should be obtained by your
meter and will often be higher.
