Air Intake Valve; Coil; Coil Winding Resistance; Coil Checking - APRILIA SX 125 Service Station Manual

Electrical system

Air intake valve

Air valve resistance 70 - 80 OHM at 25 °C (77 °F)
Not powered: closed valve
Powered with 12V: open valve

Coil

Coil winding resistance

Primary 0.11 - 0.21 Ohm.
Secondary 4.3 - 8.1 kOhm
Checking
Use a pocket tester to check the coil. In every case
the continuity of the primary and secondary wind-
ings must be checked. The Ohm reading need not
be exact, but if the windings are not damaged, their
continuity must be detected according to the fol-
lowing Ohm resistance values described above.
