FIAT PUNTO TRAINING OUTLINE
(75 & 90 HP) After Sales Training
Under specific acceleration loads, the ball is released from the magnetic retainer and gradually
comes out of the tapered support with an upward movement, according to the cone angle.
Above the ball is a quick-connect mechanism (3) that makes up the normally closed (N.C.)
electric circuit.
The mechanism changes position when it is hit by the ball, from N.C. circuit to normally open
(N.A.) circuit, thus cutting off the fuel electric pump ground circuit.
The switch can be restored by pushing a button protected by a flexible cover (4).
NOTE. Following any collision (even a slight one), the switch shall not be actuated again if fuel
smell is smelt or leaks are found from the fuel feed system. The fault shall be located and
remedied, to avoid the risk of fire.
Otherwise, if no leak is noticed and the vehicle can be started, press the button to actuate the
electric pump again.
