I'm working on my recently acquired '42 Farmall H that my grandfather bought new. Been in the family ever since. Having charging system troubles. It has been converted from a cut-out on the generator to a voltage regulator mounted under the gas tank, but still 6V, positive ground. Wasn't charging when I got it. I took the generator & regulator to our local shop. Generator was good, regulator not. Bought new regulator and it did charge, but only 2-3 amps(on a new ammeter) and the ammeter fluttered a lot & constantly, especially at higher RPM's. I tried another regulator, with no success, same problem. I then took both regulators and generator back to the shop. One regulator was good, the other not and generator checked good. N ow I'm beginning to suspect a back connection somewhere in the old original wiring harness which had been modified when the tractor was converted to a regulator system. So I replaced it all with new wiring. There are no lights hooked up, only the distributor. It is still not charging. I remembered some of the tests you have posted in the past, so I grounded the field terminal. With the field terminal grounded I get about 7-8 amps and no more fluttering of the ammeter. What is going on here, did I get two bad regulators or what? Any ideas? This is beginning to make me appreciate my hand start John Deeres with only a magneto to worry about. Thanks, Paul

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
