Here are examples on how to find defective components on your PCB1.3.
Problem: Battery does not charge.
Solution:
- Remove charging relay K3.
- Connect charger, ensure charger cable (-/GND) is connected to the side marked as '-' at the PCB P42 connector and charger cable (+) is connected to the side marked as '+' at the PCB P42 connector.
- Ensure the yellow station LED near charging relay is going ON.
- Using a multimeter (volt/DC) measure voltage directly at charger connector P42, ensure charger voltage at P42 is approx. 29V.
- Measure voltage between charger P42 GND and left and right side of the fuse EF1. It should again have approx. 29V.
- Disconnect charger.
- Insert charging relay K3.
- Connect charger again. Ensure the charging relay is going ON (makes a hearable 'click' noise).
