Troubleshooting high-current error code 103
1. Verify that the current sensors (CS1 and CS3) and cables are not damaged.
2. Exchange CS1 and CS3. Replace the faulty sensor if the error the code is not displayed again.
3. Look at the surge capacitor to ensure that it is not short-circuited. Replace PCB6 if the surge capacitor is shorted.
4. Check for short circuits from the work terminal to the negative terminal on PCB6. Resistance should be about 100K
ohm from the work terminal to the negative terminal. Resistance will vary if you have a voltage divider for a height
control system.
