I have 1999 Honda Odyssey that is eating batteries.
I recently replaced alternator....but now something is eating batteries. I've had two batteries totally drained , even after I charged them overnight on a slow 3amp 12v charger. What should I do next to resolve the problem, short of having an expensive mechanic shop tear into the problem.... I am living on restricted income and cannot afford to have mechanic do guesswork at the hourly rate they charge. What can be tried on a shoestring budget???
