i thought i'd make up a thread with some pictures of a few common Stators
and list the Ohms readings if anyone needs to check theirs.
i'll add some other stators when i get a chance next, and some ignition coils too
Lifan 125 type stator and flywheel.
the black coil to the left is the Source coil this coil supply's the power to the CDI
and to the right is the Lighting/Charge coil for charging battery's for starting and lighting etc
and the small black box at the top is the Pulse/Trigger coil which tells the CDI when to fire.
and the black rubber plug and contact, with a single green w/red striped wire in the centre of the stator is not connect or if it is, it's for a start in neutral only engine (used in electric start engines, and some older pit bikes)
a lot of the time the lighting coil isn't used and can be left disconnected with the 2x lead terminals insulated and taped back onto the stator wires
to test the stators' reading you will need a basic multimeter.
follow the loom upwards to where it joins the main loom.
unplug the black w/red striped wire, the blue w/white striped wire, and the green wire.
these are the 3x wires that your bike needs to run
to measure the resistance on the source coil-
get your multimeter out and set it to 2000 Ohms
put one lead from your meter to the black w/red, and the other lead to the green
you should get a reading around 380 Ohms give or take 10%
and to check the pulse/trigger coil-
set your meter to 200 Ohms
put one lead to the blue w/white striped wire, and the other lead to the green
you should get a reading around 130 Ohms give or take 10%
if your meter doesn't move and give a reading when you touch the leads to both the coils' wires, it either has a flat battery, or there is not a complete circuit.
so you might have to try cleaning up the terminals on the ends of the wires
or there could be a break in one of the wires, or a break in the windings of the coil.
if you get a reading, but there is a big difference to the above readings, that could indicate that the coil you are testing is faulty, or that it has shorted across a couple of the windings
Adjustable Timing Daytona style/Lifan 150 Outer rotor kit
the bottom picture shows the coils
the 2x coils on the right of the mounting screws are for the Source coil
and the Pulse/Trigger coil is the black box at 9 o'clock on the stator plate
testing the coils,
unplug the 2x wire socket from the stator loom, where it joins to the main loom
set your multimeter to 200 Ohms
to test the Source Coil,
put one lead from your meter to the black w/red wire, and the other lead to the red,
you meter should have a reading around 10.5 Ohms give or take 10%
to test the Pulse/Trigger coil,
unplug the pink and green w/white striped wires,
put one lead from your multimeter to each of them,
you should get a reading around 130 Ohms give or take 10%
as above if there are no readings, first check your connections,
if you do have a reading but it is a lot higher/lower, then the coil could be faulty and need replacing
YX150/YX160
testing the coils,
unplug the black w/red wire, blue w/white wire and the green from the stator loom, where it joins to the main loom
set your multimeter to 2000 Ohms
to test the Source Coil,
put one lead from your meter to the black w/red wire, and the other lead to the red,
you meter should have a reading around 250 Ohms give or take 10%
to test the Pulse/Trigger coil,
unplug the pink and green w/white striped wires,
put one lead from your multimeter to each of them,
you should get a reading around 550 Ohms give or take 10%
as above if there are no readings, first check your connections,
if you do have a reading but it is a lot higher/lower, then the coil could be faulty and need replacing
Zongshen Z155HO/Z160HO/GPX125
testing the coils,
unplug the 2x wire socket from the stator loom, where it joins to the main loom
set your multimeter to 200 Ohms
to test the Source Coil,
put one lead from your meter to the black w/red wire, and the other lead to the red,
you meter should have a reading around 10.5 Ohms give or take 10%

Late addition
Daytona 150F, 150FDX, 150FLX, 190F, 190FDX, 190FLX stator reading's
Testing the stator, it measured 360 Ohms on the Black w/Red striped wire and the Green wire from the Source Coil/s, and 260 Ohms on the Blue w/White striped and Green w/White striped wires from the Trigger Coil.
