If only everyone would learn to trouble shoot with a volt meter, or even a test light, and do it UNDER LOAD!

That seems to be the sticking point, people are intimidated by a volt meter, guess they are afraid they will burn it up... So what, go buy another one for $5! LOL Still better than a trip to the repair shop!

But it is always better to test with some load on the system, turn on the lights, turn on the ignition, or have an assistant hold the starter switch.

Most times, a corroded connection will show to be good until a load is applied, then the resistance will go up, the voltage will go down.

Something else I've seen, battery cables corroding under the factory molded rubber insulation. Impossible to see until it either swells or burns through.

Another, an eye terminal on a stud with a nut or a bolt into a threaded hole. The connection gets loose, the nut or bolt arcs to the thread, welding it in place. Check it with a wrench, feels tight, 'cause it's welded... Give the cable a twist, find it to be loose!

Murphy never rests!

Today's Featured Article - Fasteners: The Nuts and Bolts of Nuts and Bolts - by Curtis Von Fange. The nuts and bolts of nuts and bolts is an interesting and essential piece of knowledge that applies to our older tractors. An improperly torqued capscrew on an engine head or a shear bolt that is too hard on the driving shaft of a bushog can create havoc and make an expensive and uncalled for repair. Let’s examine the purpose and design of these fasteners in order to ensure their proper use. Fasteners are probably one of the aspects of mechanics that is given the least amount of thought. ...
