1997 Toyota sr5 4 runner. Took battery out to be charge put back in now car won't start

Did you install the battery backwards with reverse polarity. I sure hope not.

You mean put the negative on the positive ...no didn't do that Or are you talking about something else

Umm maybe she put the battery itself in backwards if so what does that do Now I'm worried

If it was put in backwards it can burn out all kinds of things. And yes I did mean positive to negative.

So if it's hooked up right... do you have any idea why it won't start and has head lights...? Could it be a security system or something

So if it's hooked up right... do you have any idea why it won't start and has head lights...? Could it be a security system or something if so do you have any idea what I need to do..please and thank you very much for your reply/help

Ok went and had battery checked and it was bad so bought new battery and still it won't start.... it would just make sense that when I hooked up battery after being disconnected and the horn started blaring that it would be an indication that it activated a security feature of some sort but now I have no idea what to do...can anyone help please and thank you in advance.

Did you ever find an answer? I have the same issue.
