Well, the voltage stabilizer is not the problem, but the weirdness continues.

Removed the stabilizer, put the two green wires together, and returned everything else to stock (ignition bulb, fuses, VR connections). In the process of this I inspected all the firewall fuses and noticed that fuse 4 was in fact blown. I replaced both fuse 3 and 4.

Turned the key to "ON" and the radiator fan turned on immediately, with the ammeter dropping appropriately. No ignition light. Not sure if I mentioned it, but last week the manual fan switch broke, so I couldn't turn the fan on. Not sure why a normally open switch is now closed? Started the engine and the ammeter didn't move (no charging). Shut down the engine and flipped off the battery switch.

Inspected the firewall fuses. Fuse 3 blew again. Fuse 4 is intact.

Think I'm gonna go binge watch the Twilight Zone!
