I have a 2003 Honda odyssey and I am having electrical problems I have replaced my battery three times in the last five months. I had the alternator and starter checked and there is no draw when it has been tested. I did have an issue with my radio smoke from power button coming out of vents and it is still working and my anti-theft system sometimes locks the doors when you do not lock the doors yourself. What could be the reason that my Odyssey batteries are draining very quickly for last few months? I had the radio removed once when my kids were young could there be a coin still in there and could that have made wire short out and make the radio smoke and do you think the radio is draining the battery or a bad wire from radio? I would like radio removal instructions as well. Do you think if I just disconnect the radio all together it should be fine? Please advice. Thanks.
