I have a 1969FJ40. New battery, new alternator, (new volt regulator which I haven't installed yet). I don't have very good connections between my fuses and the copper clips they snap into. I'm always having to press on a couple to get my blinker to come on or to get my heater fan to turn on. I even added a drop of solder onto the clips in hopes to get a better connection with the copper rivet that connects the clip to the screw/ wire holder. Any, that's just some background info. My question is how do I read an ammeter? On my guage cluster is an ammeter (amp - meter). On the left is -30 and on teh right is 30+. Most of the time when I am driving the needle is just a little to the right past center. But, when I turn on my blinker the needle bounces way down and back up keeping tempo with the blinker. Does that indicate a short? Does a well running vehicle with good wiring hold the ammeter needle on center whether you run accessories or not? Or, is the ammeter going to fluctuate with every draw on the electrical power? Someone care to elucidate.
