Using the voltage-sensing wire can make a big difference in some cases. I just built a portable gas-driven battery charger. It has a 72 amp Delco 12SI hooked to a 6 horse gas engine. 10 feet of charge cable leads with #2 copper. Alternator was one I had laying around that already had an aftermarket self-excite "one wire" regulator. I tried charging a solar battery bank with it and got pretty fed up. When charging at high amps - it had 14.2 volts at the alternator but only 13.7 volts at the battery bank. The battery bank would never rise above 13.7 volts because the alternator thought it was at 14.2 volts. I finally took the alternator off and stuck in an OEM Delco standard regulator and ran a separate sense wire to the bank with #10 copper. Now it works great and the battery bank comes up over 14 volts.
Obviously on a tractor with a battery three feet away from the alternator, it does not make as big as difference.

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
