Another electrical problem

I would test out the alt. You may have driven the battery to die. Also, check the belt and tensioner.

It's been my experience that when a battery dies of old age, it often does as you describe: run fine, then not start, and not take a charge. To be fair, it usually gives hints that aren't seen as such; slower starts, drastic dimming of lights when starting, for example. Then, it won't accept a jump, because it's shorted internally. Obviously, the cure is a new battery. Good luck!

Start with the simplest thing first. Inspect and clean the battery cable connections. If they look good, check the alternator output. Then use an ammeter to see if theres a drain on your battery when the cars off. It's good to rule out all these possibilities before rushing out to buy a battery.

Thanks to all for the advice. I did go buy a nw battery today, then when we got home I disconnected it until I can get it into the shop to have the alternator checked. Appreciate the help, and the battery did look to be the original one.
