Thanks:

I'm taking this all in.

I want to keep the 6 volt system for now, one of my other hobbies is antique radio and I'm not giving up tubes yet.

I considered looking for a DC to DC converter that would cover the load of the 12 volt A/C of which the biggest part is the blower, then I could remove the 12 V alternator and the 12 volt battery.

The 6 volt system seems to have good output and I drive with the tube radio, headlights and both heaters on all the time and it kept up quite well.

If it had a good 12 volt battery it would probably work just fine but in stop-and-go the current battery won't hold a charge so the A/C slows down at red lights and has a hard time getting back up to speed.

My A/C compressor does have a second belt "V" and I like the suggestion of driving the alternator from that.

I see some of you have worked this problem out previously.

Tonight I'm driving home from work in the Packard with the air on.
