Hi Erick, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, does "...power before the coil..." mean that there is IGN+12V at the 1 wires supplied to the ignition coils? ...depending on which Mule version, usually a yellow/white wire? If yes, would there be pulsating voltage on the other wire to the ignition coil when attempting to start?
Still, proposed preliminary checks (if have not been done):
IF there is ignition +12V supplied to 1 terminal of the ignition coil and there is pulsating voltage on the other terminal of the ignition coil (when attempting to start), THEN by induction, there would be high voltage produced; spark.
IF both the above voltages are present BUT "...still no spark...", THEN the ignition coil becomes suspect.
This would hold true if the "...original igniter...bad..." caused the failure to the ignition coil.
