Can anyone offer some advice? My 84 GMC S-15 seems to be having some electrical problems. I went out to start it the other day and I get nothing! I have no power what so ever. It was running just fine the day before. Being fairly non-mechanical I tried the basic stuff I know, try jumping it, check the battery cables...nothing still. So if anyone can offer up something to try, I'd owe ya a big ole hug. Thanks.
