Good evening all,

I have a trove of over 20 coils to sort through off vehicle. Is there an easy visual check to see if they are ballast / non ballast / electronic ignition or shall I just rely on the resistance values in the primary windings?

Should the secondary windings have a resistance of 7500-10,000 regardless of the type of coil?

I had a look at the FAQ but most identifications were for on vehicle.

Thanks!

Just measure the coil resistance across the LT wires (primary circuit)

3 ohms not ballasted

 

1.5 ohms ballasted

 

1 ohm for electronic 59 & 65 type dizzys.
