Jon, My standard generic troubleshooting procdedure is linked below, its NOT perfect or all inclusive but its a start. My friend Bob M has a good flow chart which also helps.
The older systems used a Cutout Relay (BAT and GEN/ARM Terminals) and the Gennys FLD wired to the LHBD light switch which could be set for Low or High charge. The newer used a full fledged 3 or 4 terminal Voltage Regulator where the Gennys FLD wired to the VR and NOT and low high charge switch for automatically regulating the rate of charge. (LHBD can still be used to turn lights to Bright or Dim) Its possible to convert from a cutout relay and LHBD system to a VR by wiring the VR correctly
BAT on VR to load (NOT battery/starter) side of ammeter, same as wire from BAT on cutout up to ammeter before.
GEN/ARM on VR to gennys ARM post
FLD on VR to gennys FLD post AND NOT TO LHBD SWITCH
and NOT use the gennys FLD wired to the switch but VR instead.
