Turns out the VR I got from the repair shop last spring was way out of adjustment. He put it on the stand and set it to where it out to be and now it works great!

Now onto my M. I have a 39 M converted to 12v with a generator and a magneto. None of Farmall Bob's diagrams seem to apply directly to my setup. I am running Batt. Terminal on VR to left side of ammeter when looking from back. L terminal of VR also runs to left side of ammeter. Lead off of right side ammeter goes down to starter button. It has one of those weird looking old light switches with a resistor built in. Nothing hooked to that right now. Connections between VR and genny are normal. It is not charging. Care to take a stab?

If it were wired correctly, as Jim and Tractorman pointed out, the VR's L terminal feeds hot battery voltage to loads (lights, ignition etc) INSTEAD OF them being fed off the ammeter terminal that wires down to BAT on the VR. The loads still get hot voltage to work IFFFFFFFFF fed from the ammeter even if the VR's L wasnt used and hooked up at all as thats what happens if you dont have the VR L terminal. HOWEVER I would do as they indicate and dont hook the L to the ammeter, but instead run a wire from L up to the light switch (for BAT input voltage) and remove any other wire from the ammeter that wires to the light switch.

Use John t analysis document on this one as well. The L terminal should be hooked to the light switch fuse input terminal. (do that, but then follow the chart). Jim

Let me see if I understand what you have done.

wire from bat terminal on VR to left side of ammeter AND wire from L terminal of VR to left side of ammeter also ???

If this is how you have it hooked up it is not correct.

The correct hookup is: wire from BAT terminal of VR to left side of ammeter. wire from L terminal of VR feeds lights if so equipped and ignition switch if equipped with battery ignition. If you have a mag and no lights, there is NOTHING connected to the L terminal.

Only two wires to ammeter, one on each post. If the ammeter reads backward, then swap the two wires on the ammeter.
