alright well ive been having a bad problem w/ corrosion on my positive battery cable & my car wouldnt start today after work. well i got it jumped & it did nothing. then i kinda wiggled that wire & the wire to my alternator & noticed that the top wire on my alternator which goes to the power box by the battery was fried! well just the terminal that connects to the alternator & the plastic cover around it. well i wanted to test my battery & alternator & they were both fine, but the guy at the store noticed that the alternator wire terminal lite up like when you burn metal & it turns reddish, orangish whater. well im thinking that is why my car is acting up & wasnt sure what to do to fix it. i could either take it to a mechanic & have them fix it or replace the alternator wire. the guy at autozone said i might have a short in the wire & didnt want me to spend 20 bucks if that wire would go bad too. any ideas on what is wrong or how to fix it?!?!!?
