I used the DVM rather than trying to see the ignition light since I'm working alone.

Ignition light side terminal grounded to block, G/R wire connected to ignition light center terminal. DVM clipped to ignition light center terminal.

With ignition "on" (no 3 fuse):
Light to VR ground 0V
Light to alternator case 0V
Light to alternator Batt terminal 13.7V
Light to all other alt terminals 0V

Turned key off, inserted fuse, turned key on. Alt spiked to -15A and fuse blew. Light did not illuminate.
