what you can check with ohmmeter

Stator coils can be checked with Ohmmeter as follows:

type of stator

Version

resistance between

Ohm


external sensor system

6 Volts black-black (lightcoil) 0,25
white-red (ignition pole)
if you get indefinite than coil is broken (or wire has bad contact)
600
12 Volts black-black (lightcoil) 0,34
white-red (ignition pole)
if you get indefinite than coil is broken (or wire has bad contact)
600


internal sensor system

6 Volts black-black (lightcoil) 0,25
red-brown (ignition pole)
if you get indefinite than coil is broken (or wire has bad contact)
500
white-brown (impuls pole)
if you get ca 35ohms, than read here
70
12 Volts black-black (lightcoil) 0,34
red-brown (ignition pole)
if you get indefinite than coil is broken (or wire has bad contact)
500
white-brown (impuls pole)
if you get ca 35ohms, than read here
70
The Sensor, (not to be found in internal systems) has a standard value of ca 200 Ohms (205 at 23C). This value changes rapidly when quickly touched with a metal object. You will not be able to pinpoint the value it changes to, as this is too quick, but there must be a change.

If sensor shakes loose and comes into contact with running rotor, it will be killed for sure as the very fine wire inside breakes. Resistance than indefinite
 
as of october 2015 there is a new, improved model of sensor introduced. Those have a more cornered shape. First batch had still coil with ca 200 Ohms.
Sensore as from production dates 4115 have coil with reading of 92ohms.

Soi if during check, you find readings not of ca 200, but ca 90 Ohm, check whether you have this new model.

Recognisable by the wire exiting at left side (seen from rear)

what you can not check with ohmmeter 

IMPORTANT: as you can see in the picture here to the left, our ignition coils contain electronics. Please refrain from subjecting them to whatever electric check you have in mind (risk mof destruction!)

except 
that you can ceck resistance of the secondary (high tension) winding as described here
Resistance is in all coils 6.3 Kiloohms 
single coils HT output against ground, twin coils HT output against second HT output

There are no 12V battery voltage going into the coils! You can not compare them to classic coils. Never introduce battery voltage into the coils (as sometimes people do and kill it thereby!)

 



you can not check any resistance values!  You can not check the advance unit directly. 

For units working with external sensor you may do so indirectly as described here

But, please check switch settings against assy instructions. Wrong settings bring problems. We do not set the switches at time of delivery as we found that they might change during packing/transport.
