Repair Handbook: Troubleshooting Roundup for Electrical System of Electric Tricycle-13

13、The fuse is burn out continuously

(1) Causes:

① Controller damaged, ② Short circuit of the meter, ③ Short circuit of the lamp holder, ④ Short circuit after cable damage, ⑤ Reverse connection of battery (after replacing the battery or using a battery holder of other brands)

(2) Troubleshooting: Unplug the battery, turn on the ignition lock, and turn off all light switches. Use a multimeter to measure the resistance between the plugs (simple contacts). If it is close to 0Ω, it indicates a short circuit in the circuit and can be detected by the open circuit method. If the voltage displayed returns to normal after removing the battery plug of the controller, it indicates the controller damaged. If still abnormal, remove the meter for testing, and the rest can be done in the same manner. If the fuse is burnt out after turning on the headlights or turn signals, check whether there is a short circuit of headlight holders or turn signal holders.
