    I have a Powertran M2170L multi tap transformer; I want to wire up to a 24 volt pinball machine
    (rated at 24v AC 3A 100VA);
    I am totally confused with the wiring Diagram on the top of the transformer (see picture)

    [​IMG]

    How do I wire this up? How I read it is A,E go to the pinball power and B-F are connected together (jumper)
    is this right

    This is the manufacturers DIAGRAM for the transformer:

    Hope someone can figure this out for me! Thanks Folks.

    Craig.

    You use A & E for the 24v circuit and jumper B & F.
    This would then series up the two 12v windings.

    A few questions relating to the 250v primary side wires and fuses for both primary and secondary sides

    1. which wire is live? - (I think this -> BROWN = live current 240v and BLUE= common 0v)? (this complies with Australian standards)

    2. where do I put the recommended 500mA fuse? - on the primary side or secondary side?

    3. what size fuse should I use on the secondary side? - (I'm thinking [100va div 24v = 4.16A] -- so 5A should do - is this correct as pinball is rated at 24vac : 3a : 100va);)?

    Yes. The 500ma fuse states on the primary, wire into the hot/live conductor.
    100va/24 = ~4amps, so a 5 amp would be suitable.
