I went out to start my diesel and some dummy left the key on after pulling the fuel shutoff. Someday I will learn. Well no big problem I'll just get the charger. My charger is a Schumaker 40/ 200 amp boost unit both 6 and 12 volts. It has a dial timer with an off position and a dial voltage amp selector with an off position an an amp meter. I always set the selector switch and then turn on the timer. I had last used the charger on my 6v case 200. So I hook it all up set it to 12 v/10amp charge and the meter is showing 20 amps. I shut it off check all my connections set it to 12v/ 40 amps and the meter shows 80 amps. hmmm? So I shut it down and rotate the selector dial through all the positions (off, 6v/10amp, 6v/40amp 100amp boost, 12v/10 amp, 12v/40amp 200amp boost). Set it back to 12/10 and same thing happens, so afraid something might get burned up I turned it off. Then just out of curiosity iI set the selector to off and turned on the timer and it runs and shows 20 amps. What the ???
So I think that something is stuck on the 6 volt setting. One final thing I did was take it to the 200 and hook it up at 6/10 and again at 6/40 and the amperage read correctly. Does anyone have any suggestions other than get a new charger? I've had this one since the early 80s and it has saved me many a time. Phil

Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
