There is so much confusion on the collector boards about ignition coils, they need to be measured between terminals so the user is certain of what he is installing. The resistance is what determines how much current (amperes) flows through the circuit.

According to hemming motor news "Coils come in four basic types, 6-volt or 12-volt and either internally resisted or externally resisted. Any coils that do not have an external resistor have one built into the coil itself. "
