Charging Indicator Circuit
The green wire from the regulator-rectifier is used to
activate the charging indicator light. With the
keyswitch in the ON position and the engine not
running, the charge indicator light should light
(Figure 14). With the engine running, the light
should go out, indicating that the battery is being
charged.
If the charge indicator light does not light when the
keqswitch is in the ON position (engine not
running), check the bulb and wiring.
Figure 14
Test Charging Indicator Bulb and Wiring
The following test will be made with the meter in the
+))))) position (Diode Test) (Figure 15).
Figure 15
• A continuous tone indicates continuity
(complete circuit).
• No tone indicates no continuity
(incomplete circuit). An incomplete circuit
will be displayed as “OL.”
1. Place keyswitch in OFF position.
2. Disconnect output harness at regulator-
rectifier.
3. Check continuity between charging indicator
wire (green) and ground (Figure 16).
Figure 16
• If meter indicates continuity, bulb and
wiring are OK. Replace regulator-rectifier.
• If meter indicates NO continuity, replace
bulb and re-test.
• If meter indicates NO continuity with new
bulb, the problem must be a broken wire
(open circuit) in the charging indicator
circuit.
4. If the charge indicator light remains on with
the engine running, test the regulator-rectifier
DC output. If output is within specification
and charge indicator light remains on,
replace the regulator-rectifier.
