It took me a few weeks to get it all straightened out becasue I got a defective replacement alt from the parts store and I didn't have time to swap it out again.

My problem with this type of mod is that Energy = Energy. If you are not charging your battery using the alt, and you charge it from the grid you are still paying for the energy on your electricity bill instead (likely at a "cheaper rate").

Also isn't a battery charger plugged in to a car battery for 8-10hrs at a time going to waste energy once the battery is "full". Kind of like people complaining about leaving cell phone chargers plugged in 24/7 even if they are not charging the phone.

Yes I can see that if you are able to maintain the battery with a solar panel you are ahead of the game.
If you get a good charger it will go into "maintain mode" and only give short bursts of power to keep the battery topped up. I have one of those "killowatt" appliance testers that plug into your wall and then you plug your appliance into it. I can test what the drain over a few days will be for you, because I have an on board maintainer for my CRV as it sits outside in the cold most of winter, and I rarely drive it. The maintainer works flawlessly, and in the dead of winter i hop in, and it fires right up, so I know the maintainer does its job.
