Use of external power supply
When the battery power cannot meet the engine starting, it can be started with the help of external power supply.
When starting with external power supply, special spring clamp with complete insulation at both ends shall be
used to prevent short circuit and fire jumping caused by wire contact.
Battery a is the on-board power supply, and battery B is the external power supply.
The positive pole 1 of the external power supply B is connected to the positive pole 2 of the on-board power
supply a, and the negative pole of the external power supply is grounded on the metal body of the vehicle. Start
the engine. If the start fails, wait a few minutes before starting the next time to protect the engine and battery.
Before removing the starting wire of the external power supply, let the engine run for a few minutes, then discon-
nect the negative wire and ground wire, and then disconnect the positive wire.
