If the wire is loose at a connection, find a wrench that will fit it and tighten it.

My 1996 Nissan Maxima started making weird noises, first it sounded like something was loose. The sounds were coming from the front tire area. I continued to drive the car for while and the noices just got worse. I was driving 50mph and it felt like the tires were going to fall off! I discovered the front L&R Stutts were shot! I had it fixed and now smooth as ever. Not sure if your weird noices are the same as my weird noises.
Well, It could be your battery or alternator or both needs to be replaced but it could just be loose or corroded battery cables
AnswerIf its not the battery, or alternator. Check your ground wire, down by the starter, to make sure its not loose.
