According to the wiring diagrams that I use, for wide frame tractors, your VR should have 4 wires.

A terminal marked "bat" with a gray wire going to the neg terminal on your amp gauge.

A terminal marked "gen" with a light blue wire going to the solenoid (large post opposite the battery)

A terminal marked "F" with a yellow wire going to the "F" terminal on the SG

And a terminal marked "grd" with a white wire going to ground.

It is also my contention that ALL voltage regulators are NOT created equal.
Meaning that voltage regulators made for different applications may be marked differently and that the position of the terminals may not be the same for all applications and that all VR's do not necessarily route the power in the same way.

Again according to the diagrams that I use, the lights do not directly connect to the VR, they are powered from the neg. side of the Amp guage (same terminal that leads to the "bat" terminal on the VR).

I hope this helps in some way.

Good luck and keep us posted.

 

Cub 128 VR

I finally got my Gravely out of the way and started the Cub 128 for the first time today.

I have the wiring figured out. But the VR I have has 4 tabs instead of 3. It has one marked L. I think this is for the optional lights. The GEN tab is on bottom instead of the side. Anyone know for sure how to hook this up?
