Need a new Cagiva Mito solenoid try on Ebay UK here
Testing the solenoid , this one i tested has corrosion on the secondary contact plates so was unable to test fully .
ill update asap .
its quite and easy test .
First test the primary coil with a multimeter set to continuity / ohms and listen for buzzer to
confirm coil wire is intact .
if it buzzes it signals a good coil so solenoid should switch at least , if not you have a damaged coil so you need to replace solenoid.
If it beeps you can then test the secondary side of solenoid and that the coil is actually switching and moving the contact plates .
Testing the secondary side of the solenoid , can be done by putting 12v to the primary terminals
you should hear a click , this tells you the contact plate is moving under the magnetic effect of the
energized primary coil .
you need a 12 volt power source , battery.
I use a power probe they are cheap and make power testing safer ( buy powerprobe here )
Power probe 12v
to energize the coil.
you should here it click , at the same time you should connect you multimeter set to continuity across the main large terminals.
the energized coil should move contact plate the connect the two large terminals together creating
a circuit and continuity , hard to explain but easy if follow below drawing.
or instead of using a multimeter you can use a test lamp , when you
energize coil the bulb should light to confirm complete circuit.
Possible problems
if the primary test fails ie , no continuity it means primary coil is damaged is faulty so solenoid needs replacing .
if secondary test fails to click it could mean contact plate mechanism is seized and
will not move to make electrical contact , sometime throwing solenoid to the floor or tapping with
hammer will free it .
if it clicks bit test light or multimeter fails to light or signal continuity then the solenoid
contact plate , contacts are probably worn , pitted or rusted , sometime tapping or banging can
clean off the contacts but not often and a new solenoid is needed .
