Charging wire

Post by paudie »

I have a few questions regarding the charging of my FMD . I've bought a wire loom but its not as simple as it sounds . My question is should I have a wire feeding charge to the batterie ?if i do what colour should it be ?and where should it be coming from the dynamo ?or voltage regulator ? I may not be an expert on fordsons but I'm quickly becoming an expert on this one !
Any hints advice would be helpful

The wires will run to the regulator, and then to the battery. Not sure on the colors. A photo of what you have would help. The big wire should be To D for Dynamo. Then you have a smaller wire that is marked "F", for Field and a wire that is marked "A", for Armature. These will be stamped in the Dynamo or Generator as we say over here. The "E' on the regulator is for Earth or Ground as we say over here. The regulator will also have a "B" for Battery. This goes to the Amp gauge, and then to the big post on the solenoid that feeds directly to the battery. Dandy Dave!
Have a Fordsonful day Folks!

For early FMDs a fairly thick wire, coloured Yellow with red & black tracer, goes from D on the dynamo to terminal D on the regulator. On later FMDs this wire, also fairly thick, is coloured Yellow with a white tracer. On ALL FMDs a same thickness Yellow wire runs from terminal A [not A1] on the regulator to the main BATTERY supply lead terminal on the starter solenoid.
The field wire, RED with a white tracer, goes from terminal F on the dynamo to F on the regulator [all FMDs]
Since the dynamo is mechanically bolted to the engine block, no earth wire is required. The regulator, though, must have one, coloured WHITE with black tracer, from terminal E to a good earth/ground.

Paudie, have a look at the subject just above this one -- Fordson Repair Manual -- dated March 7th. Scroll down to my second post on March 10th and click on the website highlighted. Then click on page 54 which will download a wiring diagramme.
