I have a no. 8 awg wire from the neg batt. term bolted to the frame, not the floating ungrounded batt box. A no. 12 awg stacked on that connection point going to the reg. It has to grounded well. And it is not hooked to the floating ungrounded battery box. I do have the aluminum heat sink with the heat sink compound between the two items. See if all this sounds correct to you. On the reg. vr 115 I have the orange and yellow hooked to the load side of the switch " brown" wire. The black is grounded as mentioned. Green out to the left ungrounded brush on alt. Right brush is grounded through its mounting screw to the motor and the black hooked to it goes up to the neg. The rad. shack rects wired like the online diagram. I am going to go hook the rect to the switched brown. Does the metal body of the reg. need to be grounded? Have not looked yet to see, how the motor is grounded and I guess could that effect it? Thanks again Saga Stan lol
Yes, your wiring for the regulator is correct. The rectifier must not be connected to the switched brown. The rectifiers output only goes to the red wire, which is the supply side of the ignition switch, as well as the connection from the battery + (via the main fuse).
The metal body of the regulator (VR-115) does not get grounded.
The rectifier terminals do not need to be soldered. Some people do solder them, and that is fine. My rectifier terminals just use push on connectors, with heat shrink insulation........ the heat shrink helps to prevent them loosening. My rectifier terminals have stayed tight for about 5 years now.
