Red +, connect to the battery +; black -, connect to the battery -, please do not reverse the connection. 3. when start to use, the charger will get into the self-test procedure automatically and then enter the charging state. 4. In the process of use, the heat can be generated and it should keep the air flow freely around charger. 5. Please do not be too close to the battery when installed.When the charger is connected to the battery, there will be slight sparks, which is a normal phenomenon. Troubleshooting: When the failure occurs, the power switch should be broken and the input power line should be cut off in time, and the input line of the power supply should be carefully checked to be correct and reliable. Whether the input ground wire is connected well. Whether the output connection column is loose. If the problem is difficult to handle, do not open the shell without authorization, because there is high voltage in the machine, if not familiar with the professional knowledge to open the machine shell to repair, should contact with our company or dealer.
