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

His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
