Benelli TNT125 Service Manual

Warning:
 The injector is internally designed with a filter,
but it
is not a serviceable part because it is
designed to filter out only the accumulated
impurities between the fuel filter and the fuel
injector in the fuel line, and these impurities may
cause fuel injector bonding, flow offset and
leakage and other faults, so the fuel filter is very
important.
 It can be replaced with the fuel injector with the
same part number.
General Failure Mode and Prevention and Solving Measures in Using Process
Important note:
All the following decisions are based on normal
f
unctions of motorcycle, wiring harness and other
system parts.
Block of fuel injector:
Please clean the fuel injector by using special
devices (such as ultrasonic wave) and special
cleaning agent.
Fuel leakage of fuel injector:
Replace the fuel injector with that with the same
part number or that specified by the motorcycle
factory.
Damage of electromagnetic coil:
Please measure the resistance of electromagnetic
coil of fuel injector with a multimeter. If the reading
is about 12 (±5) Ohms, the electromagnetic coil of
fuel injector is normal; if the coil resistance is
infinite, it means that an open circuit fault has
occurred to the coil.
