I found out where the battery tray bolt was, in the wheel arc? So I removed that, the serpentine belt and AC unit. Also I scrouged from work some baby 12V sealed rechargable batteries which were going to be recycled. but still have some charge. I think I will be able to use them to test the system some way.
I am now reading up on building my own desulfator just for fun. I found some info on the web and it should be fun.
