You said your new voltage regulator indicates used with positive ground. Therefore you attach the positive terminal of the battery to the frame of the tractor. Before you start the engine, polarize the generator by momentarily touch a jumper wire from the battery terminal of regulator to the generator terminal of regulator. (some regulators are marked armature instead of generator).

The reason you polarize is so when generator start charging and the cut out relay in the regulator closes, you have a positive charge on one set of points and negative on the other point. If the points close with like polarity, the points will severely arc, probably damaging them or maybe even sticking them together.

Few regulators now days are marked for one polarity so I am going to assume you have a better quality regulator as the ones that are marked should have different metals on each point to minimize arcing and electrical wear so to speak on the points.

A good regulated 6 volt system with good full charge battery should regulate right close to 7.2 volts. If you have working lights, turn them on before starting engine and if ammeter reads discharge as it should the ammeter is hooked correctly. If reads charge you will need to reverse the wires on ammeter.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point ... [Read Article]
