wrong with it myself? *I have a 91 Madza.
*it was working just fine when i started it this morning three times
* It makes a clicking noise when i try to start it
* The lights , windshield wipers, etc. turns on
*I tried to charge it, that did nothing
* My battery connections are corroded. How do i clean those off? How can i take them off to clean it? I know that cola apparantly works.

*I don't think its the starter or the alternator, but you never know.
*this has happened before and I had to call someone to come and clean off the connections and pieces....i just can't afford it this time around...so i want to do it myself
PLEASE HELP!!!!!
