CDI/ECU measuring scheme?
Hi you all, I am new here form the Netherlands. My 2011 EC300 has no spark at this moment. Measured everything except the CDI. Does anyone know how te measure is and wat the normal Ohm readings are?

What are your peak voltage readings for the source and pick up coils (stator)?

impulse coil = 99.7 ohm and from source is 14.5 ohm. All wel within the specs. I checked earth, cleaned it all and this is ok, all other wires are checked and ok, ignition coil to sparkplug checked and ok. so my thoughts are CDI but i need resistance figures to check.

Not resistance, but peak voltage, measuring what the stator actually outputs voltage wise. Should be at least 4 volts for the pick up and around 100v for the source coil at kicking speeds.

Meters are great but not everything can be verified with ohm readings, cdi being one of them, the stator due to failure modes can also pass and yet still be faulty. Try AC volt tests as Nate says. Stators do fail after time. KTM style replacement.

Can't really check resistances of transistors and diodes. Best bet is to swap with a known good CDI module. |
