(1) Causes: 

① Cartridge fuse burnt out, ② Battery damaged, ③ Cold joint and open circuit of battery wire, ④ Ignition lock damaged, ⑤ Poor battery contact or plug contact

Test the output voltage of the battery with a multimeter. If no voltage, check the cartridge fuse, fuse holder, battery and battery wire for open circuit.
