Another M wiring question

I know there has been a lot of wiring questions lately so I hate to pile on with another but here goes. I posted last winter that I was setting up an M that I got in disrepair on a 12V system. I kind of walked away from it for a couple of months and forgot what was what. It is a 39 M with magneto ignition, a 4 post VR, set up for 12V. The gen shop set the generator and VR for 12V. The following is the way that they told be to wire the tractor. Wire from gen post of VR to ARM post of gen. F post of VR to F post on gen. L post of VR to left post of ammeter. Batt. post of VR also to left post of ammeter. Cable from negative post of battery and wire from right post of ammeter to top post of the starter button. Cable from bottom post of starter button to post of starter. Cable from positive post of battery to tractor frame for a ground. Does this sound right? I looked at Farmall Bob's diagrams and didn't see anything for a magneto ignition with 4 post VR set up on 12V.

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th ... [Read Article]
