Looking to upgrade the coils on my bike, Anybody know the resistance to test EF EFE coils at?

looking at second hand not looking to pay over £40 but obviously want to test them before fitting.

One of my existing is actually heating up the frame with the bike ignition on but not running.

Nice Pedda, I probably deserve that but no, good 1980's coils still count, especially as under seat not seen
