Greetings to all: I;'m new to the club but am the owner of my second 325. Trying to troubleshoot the cause of my 325 with 285K miles not starting unless I get it jumped off. When I turn the key in the ignition, there is no noise! Notta! As soon as I jump the battery off it will start right up. The car will start up again once I turn it off, but when I return hours later, the car will not start and again not make a sound. Before I replace the battery don't know it's age, are there other possible causes? Thanks for your feedback, V in Rich VA..
