Having problems with your 2003 Mitsubishi Diamante ?
My 2002 Mitshubishi Diamante will drain a new battery in a week unless I drive it. I've always suspected the alarm system. Is there a way I can disconnect the alarm or is it a different problem. The dealership didn't help telling me that the drain was imperceptible.
