My B was running great and died suddenly. No spark to plugs but power to the coil. The coil was new six months ago with maybe 2 hours in it. Could it have gone bad and how do I test it?
Thanks in advance for helping!

Re: Ignition coil
One thing that will kill a coil fast is if tractor has been converted to 12v and no resistor added to hot wire to coil. If it's 12v buy a coil w/ built in resistor. Then you don't need to have external one and they are about same price saving you some $ & time.

Re: Ignition coil
Ignition points require around 6 to 9 volts to function without arcing/burning. 12 to 14.5 volts to the ignition points and they will arc/burn.BullDAWG wrote:One thing that will kill a coil fast is if tractor has been converted to 12v and no resistor added to hot wire to coil.

OP was talking about coil going bad, I was just saying if it was converted to 12v that might explain why coil went bad so fast. But Rod does need to check points and condenser also as they will also cause a no fire condition.

Re: Ignition coil
Thanks all. I bought a new coil and it fired right up. I do have an external resistor in line so should be good to go. Thanks again…I love my B!
