Hi People.

I have an Aprilia V-twin motorbike and i am trying to work out for 100% certain if the OEM coils are CDI or Inductive?

What i know:

1) constant +12v power is provided to the coil pack direct from the main fusebox on a 15amp fuse
2) 2 wires from the ECU control the coils 1 for each cylinder. The OEM ECU is providing a ground for each coil ( i assume this is controlling the dwell/spark timing by providing a ground to collapse the field in the coil? )

Anyone know for 100% what this config reflects, either CDI or Inductive coil or if there is any other way if testing to find out?

Thanks

Definitely inductive here. CDI coils are not wired to a constant 12 volts - one end is sent a high voltage pulse from a CDI box, the other end is grounded (possibly through the same CDI box or sometimes to the bike frame directly).
