Electrical problem help

[jpmxrider489]

Just to get this started Im a complete dummy when it comes to wiring and electrical and meters.

Ok so I think I put my battery in backwards but anyway a big spark happend. I changed my battery terminals. My battery is fully charged. I read multiple threads on this. When I tried to start it my wipers just came on and so did my fan. My alternator fuse blew. After replacing that I thaugt it would start bit I was wrong. My lights come on dim. So I tried having two batteries hooked up. I had mine and jumper cables on the second. It finally started but when I take the jumper cables off it dies out and stalls real quick. I thaught it was my alternator so I took that off and took it to advanced and pepboys and they said it was fine. The alternator is still off the car. What can this be.

Same Battery that you installed backwards?

Sounds like you need to have the battery tested.

Not the same battery I put in backwards and I hook up the charger and its full.
