First off I know NOTHING of cars so sorry if you cant understand me. Please get back ASAP I may sell it today I am trying to but if it works I wont need to.
I bought a brand new battery so I doubt its that, my alternater is bad from what I've heard from auto zone. I have connected the battery correctly with help, and on the negative cord there is a little yellow cap and coming out of that is another cord, going to wherever I have no clue so I hope you understand me. It had like a circle with a cog looking thing in the middle and I am wondering were it goes to my dad says its useless but if it was why would the there be a wire going to the yellow cap and then going somewhere else not just a cord directly to the negative cord is there a meaning to that cog looking cord or not?
Again sorry if you don't understand I know nothing of cars my brother bought it for me and my little sister for a present but its been sitting there for years and I only drove it once and it died when I was at the mall.
