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

Re: CDI or Inductive coils
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).
