Hi all,
I have a EC 300 2019. Was running fine, until suddenly bogged down, like i hit the killswitch. It didn't start anymore.
Noticed that with a long press on the starter button, it has a very weak and inconsistent spark.
I followed some other threads about this issue and managed to diagnose:
Coil readings OK (per manual)
Sparkplug cap OK (per manual)
Stator OK (per manual) also took it out to a visual inspection, everything looked good and healthy
Killswitch OK
Ground wiring OK
All connections are free of corrosion
All connections seem fine, with no visible issue
Now i'm leaning towards a failed CDI.
The sticker on the CDI is too worn out to read, but it should be the early version (2 maps).
Any advice or experience?
