It is working quite well now. I installed a better battery maintainer yesterday and drove with it for the first full day today. It is 6amps (instead of 1.5) and designed for the deep cycle motorcycle battery I have adapted. Total weight for battery and maintainer is under 16lbs. I was able to run today without the alternator at all and still stay in good fully-charged down to about 60% capacity range. Current tank is likely a third straight new high MPG. It is at 64.4mpg this time (even though ambient temps are lower, nights are longer, and work has been requiring more early morning and after dark commuting). With the alternator totally off all the time now, I think this tank average may climb during the last 150 miles of my normal 600 mile range. I'll post a writeup of what I have done as soon as I can.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
