Try changing your batt. term. wires sometimes they get corroeded from the inside and will not carry a charge.

You can take your battery to your local auto parts store and have it checked. Most of the battery wires do get corroded and need to be replace as well as the terminals. Average cost for the replacments of wires and terminals $15.00 Dlls.

Spend a couple of bucks, get one of the little battery hydrometers, I think they're called, and test each cell if possible to do so...
