Mazda B2200 won't start

Hello, hope some can help. i have a 1990 Mazda b2200. i hooked up a battery that i bought yesterday. i thought the battery was correct when i installed it. it was the wrong battery. the + and - were hooked up to the wrong terminals. there was a spark. went back and got the correct battery made sure everything was correct. i went to start it up and nothing happened.

i know i fried something could you tell me what it was?

thank you.

Welcome,

Did you check all the fuses? Check both under the steering column and in the engine compartment on the passenger fender well. Dan

i'll check that out.
