Please someone out there help me???

Ok I am here seeking help because I made a huge mistake. I bought a new battery for my 2005 Toyota Corolla, being none the wiser I hooked the new battery up backwards. I went to start my car, there was a big spark at the battery (that's when I realized something was wrong - plus it didn't crank or anything) so I replaced the battery again, this time being super careful not to make the same silly mistake, however when I turn the key my car does absolutely NOTHING. It doesn't get power to it in anyway. Please don't judge me for not knowing better than to hook a battery up backwards, I am a young single mother who must do everything on my own. I do not have any men in my life to help in such situations. So that's why I'm here, I just really need some help. I haven't a clue about cars. Any sound advice is very much appreciated!

Honestly I don't know anything about Toyotas..
BUT in an RX7 hooking up the battery backwards will blow the main fuse...and then some.

And then some? Shucks. So as an educated guess, what kind of price range am I looking at for the main fuse? And can I get that at a normal parts store? Thanks!

The fuse is rather cheap and you should be able to find one at the local auto parts store.

Yo,

Pop your hood and open your under hood fuse box. Inside you'll find a 120A Alternator fuse. You should be able to look in the top and see if the little piece of metal is broken inside.

This is the piece of metal that SHOULD NOT be broken.





If thats not blown, you most likely fried your ECU.

Should be similar to this

Which brings up the question, why in the hell aren't batteries made with the + terminal being larger than the -, and matching ends on the car so that they CANNOT be mixed up?!

same question with pumps at gas stations. Petrol gas nozzles should be round and diesel ones oval....these will match on the filler neck of the cars so you can never put in the wrong fuel. Why it doesn't exist I don't know

I thought there was a size difference in the nozzles between diesel and gas? Never owned a diesel, and have only filled on a handful of times so I could be entirely wrong

The diesel nozzle at the car pump is a bit bigger, or seems like it is anyways. Pretty sure itll still fit into a cars filler neck. The pumps for big rigs are definitely bigger. Most trucks tanks are in excess of 100 gallons.
