Vespa GTV 250 i.e.
Injection
Check the efficiency of the injection load relay.
Check the resistance of the energising coil be-
tween pins 86 and 85: 40 - 80 Ohm
Apply a voltage of 12V to pins 86 and 85; make
sure that there is continuity between pins 30 and
87 of the relay.
Check the power supply line of the injection load
remote control energising coil: after switching to
"ON", make sure there is battery voltage, for two
seconds, between the Red-White cable and Black-
Purple cable of the remote control base. If there is
not, check the continuity of the Red-White cable
between the fuse box under the saddle hinge and
the remote control base and of the Black-Purple
cable between pin 20 of the control unit and the
remote control base.
N.B.
CONTINUITY TESTS MUST BE CARRIED OUT WITH THE
COMPONENTS DISCONNECTED. (RELAYS, CONTROL
UNIT, FUSES ETC.).
