I came across a wiring diagram for the starter motor in a Lister Petter Handbook. They recommend a 37/0.9 from the battery to the starter and 80/0.4 between the starter and the dynamo. They must have forgotten that physical quantities consist of a value AND a unit. Do you have an idea which units they are referring to? Neither AWG nor SWG or mm^2 seem to make sense here.

Hello,
I have a Lister ST1 with a Brush SCTF117 alternator. This seems to be a combined alternator that generates both AC single phase and DC 12 V. It looks like the 12V part can be used to start the engine too. The alternator has two slip rings and a collector. I have three external power resistors and I suspect a fourth to be missing. One of the resistors controls the charging current for the battery.

Unfortunately I found many wires disconnected so I need to know how to connect again. You could help me by:
a) Post connection diagram No. E9840256
b) Tell me the type of the AC and the DC machine (synchronous/asynchronous, series/shunt wound)
c) Tell me how many resistors there are and if there must be another device like a voltage regulator

Any help appreciated.

Regards, a Lister enthusiast
