I have a 69 and a 70 and both have this thing about the size of an AA battery that has a wire going to the voltage regulater. What does this thing do? The one on my 69 is loose and the guts are spilling out of it. I haven't messed with it cause she's running fine. Should I replace it or can I get rid of it? I need to know what it is called at least so I can order it. I was thinking it is some kind of resistor for radio noise.. ??
