No crank after accidental spark to VR

I’m installing a ln MSD 6AL along with a new ready to go MSD distributor. I’m was trying to chase down ignition 1 and 2 wires to jump together and send to the 6al. I stripped one of the blue wires to crank test and verify it’s the ignition 1. When I cranked with it attached to the voltmeter, I saw a spark and noticed it fell over and touched the voltage regulator, essentially sending 12v to it. Now the starter won’t even crank over. I still get dash lights and 12 volts to the brown and blue wires but no crank. Did I fry my voltage regulator? I don’t see why the starter wouldn’t start.
