I'm sorry, Jesse, I will keep my n00b fgt logical processes to myself as I'm just a damn gromulated bozo lowdo and should just keep my posting to threads about Obamacare in OT. Wayne is right; if it needs more power then a lower voltage coil will work harder to give the bulb what it needs. That + shim and I should be blasting by yesterday.
CJ, I've used two different brand new regulators to no avail, but the next step logically is the coil, so onwards I shall go. No visible shorts in the wiring on the stator or anywhere else.
