I had an interesting experience that I thought I would share with you all. The other day I was out to one of my customers farms on a service call because he was having problems starting one of his tractors. When he called me, he said that sometimes the starter would work and sometimes it would just make noise, the solenoid was clicking. Sometimes the starter sounded like it was dragging.
When I got to the tractor I hooked my volt meter up to the battery cable on the starter solenoid. I got a reading of 12.5 "not bad" I then turned on the key switch and the voltage dropped 10 volts. I then turned on the light switch and boy were they dim. I checked the voltage meter and it was below 6 volts. At this point I got off the tractor and looked at the battery connections on the left side of the tractor, everything seemed fine. I then went around to the right side of the tractor, the terminals looked fine but as I was touching them I found one that was HOT. I cleaned the battery connections and reconnected them in correctly and the tractor then started like normal.
You may be asking yourself, why was the connection HOT, Resistance causes heat, the connection was unable to conduct the electrical flow of power. I had 12.5 volts at the starter but when I turned on the electrical load I had VOLTAGE DROP. Connections can look fine but still not be able to conduct electrical flow of power.

But, I want to talk about my tractor! We didn't even own a lawnmower, and all of a sudden we had enough grass to feed all the starving children of the bovine world. Naturally, I talked
