Famall M single wire alternator

I am doing a single wire alternator conversion to my 52 M. I have not been able to find many wiring diagrams for a one wire conversion. I have it mostly figured out with the exception of the correct placement of wires to the amp gauge.

1- What side does the wire coming from the alternator go to? Pos or Neg side of amp gauge?

2- What side does the wire coming from the stop side of the ignition switch go to? Pos Or Neg side of amp gauge?

3- What side does the wire coming from the starter button go to? Pos or Neg side of amp gauge?

Thanks for your help!
 
The heavy wire from the alternator goes to the amp gauge on the same side as the wires to the lights and the wire to the ignition switch. This will allow the amp gauge to accurately show the amount of charge or discharge. The other terminal on the amp gauge goes to the starter (heavy) switch on the starter, connecting to the stud that directly connects to the battery + post (real big wire).
If there was a generator on the M prior to this conversion, and it was positive ground, the amp meter terminal connections will need to be reversed so it shows charge correctly. The coil will need to be reversed so the negative side is to the distributor. This keeps its polarity correct. Jim
 
1. The starter button does NOT connect to the Amp gauge at all.

2. The alternator and ignition switch connect to the same side of the Amp gauge.

3. The battery supply wire connects to the opposite side of the Amp gauge, and runs either to the "live" battery side of the starter button, or directly to the + post on the battery.
