Congrats on finding the pickup coil was the problem! We normally test those on our Snap on Verus lab scope while cranking it over, no wave form equals bad pickup.
On your GM dual coil the while wire is effectively ground or - and the red is + or so the Snap On test program says in testing instructions.
My 92 has 21 milliamperes draw at rest or about 6 weeks until battery is to depleted to start it.
300K mi is a lot but cared for properly you could go 100k more. Don't replace anything because of miles verify failure or problem first.
Glad your back on the road in more ways than one!
