While you may have a diode in the alt harness the 12 KO wire to distributor and the alternator must be on separate circuits. I have yet to make diode trick work consistently.
So what year and model was the LT harness from?
Oh yeah, pulling battery cable to shut it off, bad idea, if you need to kill it, pull power to ignition coil.
I have actually just used a heavy duty GM relay key switched to run the ignition coil power. The heaviest of GM relays are the Oval ones.
