Paul, Its important that BOTH the Generator and Voltage Regulator have a good ground. Maybe run a good ground jumper to the genny AND the Voltage Regulators metallic case n see what happens.
If you put a volt meter on the battery it should read around 12.6 volts setting, but once runnign at fast RPM IFFFFFFFFF the genny is working it should rise to around 13 to maybe 14 volt range.
As posted below YES when shes running if you dead ground the gennys FLD post she should max charge sooooooooo if it charges (battery voltage rises) when you do that but NOT OTHERWISE, the problem is EITHER the VR is bad orrrrrrrrr the VR doesnt have a good ground orrrrrrr the wires open from the FLD post on Genny to FLD terminal on VR.
If theres still no charge even with FLD post dead groudeed when shes running, leave it grounded then by pass jump the VR's Cutout Relay by momentarily connecting its its BAT terminal to its ARM/GEN terminal n see if she charges then. If so but NOT OTHERWISE, THE vr'S INTERNAL CUTOUT RELAY IS BAD.
With thE gennys FLD post dead grounded AND the cutout realy by passed (GEN/ARM junmepd to BAT) the VR is essentialy by passed and out of the equation so if still no charge the genny (or other necessary wiring etc) is the problem.

This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal. As a resul
