Product use: measuring DC voltage, with anti-return, short-circuit protection and other functions
Product function: real-time monitoring of battery voltage, so that the battery can be used under normal working voltage, extending and protecting the service life of the battery and engine. Under normal circumstances when the motorcycle is not started, the voltage above 12.5V is normal. After the motorcycle is started, the normal value of the generator voltage is 13.5V-14.5V. If the voltage is too high or too low, it is faulty. It is recommended to go to a repair shop for inspection and maintenance.
Fixing method: first use a hole opener to open a hole with a diameter of about 3cm, then put the charger into the hole, and then tighten it with a screw ring!
