The charge indication lamp is connected to terminal
15 and illuminates when the ignition is switched on.
The cable of the charge indication lamp is connectedto the alternator at “D+”. At first it should be checked
if the alternator is connected to ground. When the ignition is switched on, the charge indication lamp gets
power (12 V PLUS) and “D+” is connected to ground.
Now the charge indication lamp illuminates.
When the engine is working (and therefore also thegenerator), the generator will generate power (12 VPLUS) and the charge indicator lamp will turn off because it gets 12 V PLUS from two sides and is not connected to ground.
