my weekend warrior is a 65 rambler wagon with a 500 hp 388 chevy stroker. Unfortunately, no garage so it's outside. I try to start it every week during the winter and run it thru the gears on blocks until it's good & warm.The battery is located under a compartment in the back, which has an electric window. The batt. is on its last legs so sometimes it's not enough to start it and I really don't want to replace it until spring. My question is- being unable to lower the back glass sometimes, I hook the battery charger to the alternator output (1 wire alt) and to the engine block. I charge at 2 amp max until charged. Am I damaging my alt.? So far there has been no loss in output.

No, that should not damage the alt.

I've got a better idea -- since it's outside, go by Harbor Freight and get a little 1.5A solar charger. If the windows aren't tinted much you can leave it in the back and it will maintain the battery. I'm doing that for my motorcycle, which sits under a carport during the winter.
