i have a pamco ignition if thats what ur wondering
Pamco is the ignition system, not the charging system.
So when you measured high battery voltage how long had the bike been running? Had you ridden it or had it just idled for a few minutes? Without the load of the headlight you could have sent a bunch of voltage to the battery real quick before the regulator had a chance to shut off with only a load from the tail light and coil. I would unhook the headlight and let it run with my meter hooked up, watch the voltage at the battery over the course of a few minutes. See if it jumps up to 18VDC then slowly starts dropping or just stays there. if it slowly starts dropping to 13-14 then starts modulating you're fine. If it jumps to 18VDC and stays there you have a bad regulator.
