    Help with fence charger schematic

    Understand One quick question Is the power from the transformer on the fence charger AC or. D.C.? I'm assuming AC but is it true that on a magneto it is D.C. And the power falling away induces a voltage by use of breaker points?

    Help with fence charger schematic

    also I have the wiring to rewind the existing transformer (above pic) would like to try to boost it a little the primary has only 9 winds of 16 awg wire and the secondary has 224 winds of 22 awg wire. Would 22 more winds of secondary wire increase the output by 10% ? and I've got 20 awg instead...

    Help with fence charger schematic

    This is very interesting I'm going to study that some but in the meantime I'm curious what size capacitor would produce 5 or 6 joules in a fence charger and I don't know the difference between one that runs off a battery and one that uses AC supply Guess I'm starting from scratch Is it a...

    Help with fence charger schematic

    I wpuld be happy to do that and it would be very interesting to me but I returned the broken one to the manufacturer (silver streak) and they gave me another one thru the dealer but it was a little different and I don't think it was as strong as the other one the first one was a silver streak...

    Please Help Identifing Diodes In Old Boat Motor Rectifier

    Already helped a bunch I see now that what is in the case is exactly what is in the diagram posted just mounted a different way I think I'll find the correct solder in diodes and mount a copper stand to attach them to and use the stud holes to screw the plate down, might be easier to service...
