Run the engine and check your system voltage with headlights on, etc., and see if you have a nice 13 or 14 volts, which would indicate that the system is charging normally.
The only fuse that blows is Fuse 3. I'm going to disconnect the tach. I don't know if I can get to the wiper switch or heater. I will check charging voltage assuming I can get things to run in Bob's configuration.

The system charged normally for about 60 seconds with Bob’s configuration. It doesn’t seem that charging happens with fuse 3 blown.
