I need your help please. I bought a conversion Kit in the states for my `36 Ford Coupe with a 8BA flathead. For the conversion I have to change the electric from positive ground to negative ground and so I don`t know which wire goes to which port. Where do I connect the two wire from the 12 volt field coils ( I mark they grey (2) and yellow (3) in the pics attached). Where do I connect the wire ( brown (1)) from the brushes plate? It is a 3 brushes - one is broken. What wire goes on the batterie? On the regulator (Type B for Ford) I have three ports: "L" and "BAT" and "F" Which wires go on this ports? What wire goes on the batterie? It would be great if you have a circuit diagramm for me. Many thanks for your help! Greetings Marco
Generator you have shown is 3 brush type, normally used with a cut-out. (3 brush was original for '36) It is possible to convert this to 12V but I would recommend finding a later 2 brush style. (38 on Flathead, there are a couple of versions,) To swap 2 brush style usually only needs a pair of 12V field coils. Probably the new coils you have purchased? Or, find a 12V generator from a USA ford made from mid 50's to mid 60's, use the body and armature with '38 on style end plates, job done. I cheated - used a '70s era small alternator with internal regulator. About 30 -35 A max. Not for everybody, but works good for me Garpo
Many thanks for your help! The problem is, that I need a generator with the fan-pulley. So I would like to converse this generator... Greetings from Germany Marco
Way long time ago we converted on of these. Found a set of field coils that would fit, probably Lucas . Worked in an auto parts store so we went through what we had in stock until we found a match. Used two main brushes only. Connected same as Ford or Lucas system, one end of field to ground, other to regulator. Needed a few extra revs to start charging, but worked OK. Sorry cannot remember exactly which fields we used -- it was 40 years ago. Suggest you try and find Lucas C39, C40, or C45 generators to dismantle. All common 40 years ago Garpo
