1995 Mercedes Benz SL500 V8 Four Wheel Drive Automatic
I drive my Merecedes mostly in the warmer months. During the winter I throw a caover over it and keep it in my driveway. I start it up every 6-7 days just to keep the parts moving. Recently I wnet to start it up and it was dead. I removed the battery, chraged it fully on a 12V fast charge and then re-installed it. The car started fine and the following morning it started OK, but after leaving it for 10 days in continuous cold weather the car was once again dead. I am trying to prove it the battery is bad or if the alternator is the culprit. The battery has a date of June '05 on it. I am not sure how old the alternator is or if is the original unit. What can I do on my own to prove out these two electrical components one way or the other?
