Jaguar Won't start after a jump.?

1. Joe Says: Hi guys. Yesterday my mother's car needed a jump, and some guy walking his dog, oddly enough, jumped it for her and she got home. This morning, she needed another one. When I get over and try to jump it, this time it won't work. Theres enough battery power to turn the windshield wipers on, and a few lights, but not to actually start the car. It's a 95 (i think) jaguar, and I'm pretty sure this is the second battery it's had in, so the battery's pretty old. I'm just wondering if you think the battery's just too old to hold a decent charge, or if it's something else?

Thanks

-Joe

Some vehicles have large 60, 80, and/or 100 amp fuseable links that look like large fuses. They are to protect the electronics in case some one jumps the battery backwards. Check to make sure one of them is not blown. They are usually located on the positive battery cable clamp or in the engine compartment fuse box.
