GENERATOR SYSTEM WITHOUT BATTERY (6 VOLT)

Covers 1964 and earlier Sportster Model XLCH

A. TESTER CONTROLS

Turn ground polarity selector to Negative; load control knob to Direct: ammeter selector to 100A position: and voltage selector to 6 volt position.

B. TESTER CONNECTIONS (See Fig. 51-11)

1. Remove wires from regulator "BAT" terminal.

2. Connect Regulator lead "R" of tester to regular "BAT" terminal.

3. Connect Ground lead "G" of tester to ground on motorcycle.

4. Connect Positive lead of voltmeter to regulator "GEN" terminal.

5. Connect Negative lead of voltmeter to ground on motorcycle.

6. Remove wire connected to regulator "F" terminal and connect this wire to a lead of the field control variable resistor. Connect other lead of field control to ground on motorcycle. Turn field control variable resistor to "Direct" position.

Battery lead "B" of tester is not connected.

C. TESTING GENERATING SYSTEM

1. Operate engine at 2700 RPM (approximately 45 MPH).

2. Turn load control clockwise until a 15 ampere reading is observed.

If reading is 15 amperes or more, generator is not at fault and difficulty is in voltage regulator. Make Tests D, E and F.

If no ammeter reading is obtained or reading is low, observe voltmeter reading. If reading is below 6 volts, generator requires service. If voltmeter reading is high (over 7.5 volts), the cutout relay is not closing. Make Test D following.

D. TESTING CUTOUT VOLTAGE (Fig. 51-11)
