Box on top of battery
I am not the brightest person when it comes to car
repair so I always ask. The little box that sets on
top of the battery. Not sure what it is for but it has
4 wires connected to 4 bolts. However mine is
missing a wire. Can someone please educate me
on what those are for n if it could be causing my
car to not want to start or even click like it's wants
to start. I have uploaded a pic to show what I am
talking about. I appreciate any help offered.
