Thanks for the help guys, but I'm still in the dark! I have searched google for quite a while and found nothing that I completely understand, and the seller does not know what app. they were previously used in. Unfortunately they haven't turned up yet, so I have no extra info.
As for testing them, hopefully the coils will be marked so I know which is which, but as for power supply, I have no idea what to go with. Oh, and I don't have access to a tachometer! It makes me wonder if the guy was selling them coz he was in the same boat as I am in now! |
