Yes sorry. It should be 4.2 and 4.1.

So do you think this measurement is normal and coil still oke ?

Here is my coil measurement. I think it's quite low compare to DIY on YouTube

Multimeter :
- Primary set on 200 ohm (P)
- Secondary on 20K ohm (S)

Right :
- P : 0.42
- S : 8.54

Left :
- P : 0.41
- S : 7.81

Coil cable looks bad. I think need to change them.
