Id be glad to use the VR instead of the old cutout cuz it automatically sets the correct charge rate as opposed to you manually using Low or High Charge on the light switch.
On the old cutour relay the gennys Field post wired to the light switch but you no longer use that connection with a VR, it wires as follows if its a 3 terminal (BAT ARM FLD)
BAT on VR to ammeters Load terminal, thats the same wire that used to wire to BAT on the relay
FLD on VR to gennys Field post instead of up to the light switch with a relay.
ARM on VR to gennys ARM post
If its a 4 terminal VR with the extra 4th L terminal, that terminal now feeds hot battery voltage to lights n ignition instead of them being fed off the ammeters load terminal as with only a relay or a 3 terminal VR
If its a 3 brush genny Id set it for max charge rate. Polarize the genny prior to start up.
