Good idea, BOTH the Voltage Regulator and genny need good solid grounds. When it stops charging try to ground the Gennys FLD post to see if that makes it charge?? If so then but NOT otherwise the genny itself is okay and either the VR is bad or it has a bad ground. Ya know once a good working battery is fully charged the VR's job is to back off charging, maybe its doing its job?? However if you turn on lights etc that should create enough of a load to cause generator current to pump charging amps INTO the battery as shown on the ammeter. Does it have a good working ammeter ?? they can go bad. If its charging (even if ammeter is bad) a volt meter on the battery should rise to at least 13 up to 14 or so subject to RPM, genny and battery condition.....
VR's can have oxidized or burned or carboned up relay contacts that cause problems
A 4 terminal VR that has the extra 4th LOAD terminal is used to supply current to loads like lights and ignition. Ive see 3 terminal (BAT GEN FLD) and 4 terminal (BAT GEN FLD LOAD) VR's swappped out which can still work IF wired right, perhaps thats an issue??
Check connections and grounds, take two aspirins and call me at the office

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
