Why won't the lamps turn on in my Branson 6640C Tractor?

If the lamps on your Branson Tractor will not turn on, replace the bulb if it is burnt out. Replace the fuse if it is burnt out. Inspect the cable and secure the contact if the contact of the cable is in bad condition. Replace the switch if it is defective. Connect the grounding cable securely to the body if the grounding is in bad condition. Charge the battery if it is discharged.
