battery/charging problems
 

i changed the battery post from side mount to top mount,i had to rig the wiring a little to the battery, and the post are not put on as great as they should be,but i'm having a problem with a buzzing in my speakers when i use the turn signals,wiper blades, etc. my radio also does not come on,but the tape player works any ideas? as to why the humming or buzzing sound is coming out of my speakers?
any help would be great thanks
