The batteries connection is rusted, or the engine has a poor frame connection.
4)
The start relay does not disconnect.
5)
Fault on the ignition switch or starter.
Solution proposal:
1)
Low battery level is due to the electrical devices not being switched off from the
previous day. Do not forget to switch off the electrical devices at the end of the
working day. In the case of an unsuccessful start due to a low battery, replace the
battery or connect another battery in parallel to start the engine.
2)
Clean the battery terminal, tighten the + cable terminal to create a good contact
between the cable and the battery terminal.
3)
Clean the battery earth connection terminal to ensure there is a good connection,
ensure there is a good connection to the engine frame.
4)
Repair or replace the start relay.
5)
Check and repair the ignition lock and check and repair the starter.
6)
Long battery operating times can increase internal resistance. Therefore, it is
necessary to carry out maintenance on the battery and charge the battery correctly
and replace with a new battery if necessary. The battery must be fully charged to
ensure the engine starts correctly.
