So this is a question, its an 87 so it has different cdi than the rest, tors is bypassed, stator checks out, switches check out, the black and white wire to switches is not metered to be open (which i think is supposed to be open and grounded out to shut off) it is showing resistance. Found resistance is coming from cdi unit, maybe the short is in the cdi? Black and white wire is open at all switches when disconnected at the cdi.

I believe black and white wire ground to anything will shut it down, the black and white shows closed circuit from cdi to frame/engine

Well finally got it running, bad cdi, also on the 87 vmax there is 2 black wires coming out of the CDI not one, so not sure as to which solid black to pull apart to check kill switches as to your post references
