I'm redoing my wiring harness on my 1950 8n side mount 12v with 3 wire alternator. I have the IC14SB coil.
My question is about the resistor on the wire to the coil.
I read here, "REAL 12-volt ignition coil that uses NO RESISTOR. NAPA IC14- SB is recommended" ( I think from Dell)
On another site I read, ". The ignition circuit is a balancing act between having enough resistance to protect the coil but not so much resistance that we no longer have a good hot spark"
My question is, do I need a resistor? There is already one attached to the left side of the block. It is white and has two push on connecters. It was on the tractor before I bought the new coil. If I do need a resitor or don't how do I know? What are the pros and cons and testing methods to determine if needed or not. Thanks guys!!

Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
