About half the time I shift out of gear, my RPM's drop dangerously low like it is about to die, then catches itself at the last minute. Is this a neutral safety switch issue? If so, how do I get to the switch without dropping my tranny? Also it seems like half the time my lights dim a bit according to my driving. I bought the works for a DIY grounding kit, but is this a charging issue or are all these problems relative?
