Hello, ok so you installed the battery backwards, whats going on now? The battery was dead so you replaced it and now nothing happens when you turn on the key?

Hello and welcome to JustAnswer!

Reversing polarity will instantly blow fuses and/or damage any electrical component. No mention was made of what kind of problem you're having, but the first thing you'll want to do is check all fuses. If fuses are blown then they'll need to be replaced and see if they blow again, if they do then the components they power have most likely failed.

If no fuses are blown then electrical testing will need to be done to determine what is causing the problem.

What kind of problem are you trying to diagnose?
