Precautions - Benelli TNT 25 Maintenance Manual

Precautions

Many important precautions must be understood when maintaining the electrical system. Learn and follow all of the
following rules.

Do not reverse the positive and negative electrodes of storage battery, otherwise the diode of electrical components will
be burnt.

Check the battery state before checking other parts of electrical system. To carry out the accurate electrical system test,
the battery must be fully charged.

Electrical components shall not be beat with hammers or fell on a hard surface. This impact may damage the electrical
components.

To prevent the electrical components from being damaged, do not disconnect the battery leads or any other electrical
connection when the ignition switch is on or the engine is running.

Due to the high current, do not press the start button all the time when the starter motor does not function, otherwise
the current may burn out the starter motor coil.

Be careful not to short-circuit the leads between positive electrode of storage battery and ground wire of frame

Sometimes a failure may involve an item, and sometimes it may involve many items. Do not replace the defective part
until the exact fault cause is found. If the fault is caused by other causes, the repairing or replacement must be carried
out immediately, otherwise the newly replaced part will be damaged again easily.

Make sure that all circuit connectors are clean and tight and check whether there are burnt or wear signs on the wires.
The broken wires and poor connection will affect the electrical system operation.

Measure the coil and winding resistance after the components are cooled (under indoor temperature)
