  • Transformer Installation Instructions

    Does anyone have the installation instructions for P/N: 12-862164-000 ?

    Check machine next to it. Did instructions come with it?
    I'm going fishing and camping!

      Have 3 parts and 1 instruction sheet. Missplaced I presume. The new part is color coded. Original is not.

        Brunswick A2 user manual:
        http://www.brunswickbowling.com/downloads/support/BB_Service_Service_Manuals_A2-Service-Manual_12-752828-000.pdf

        Manual page 1-82 (page 86 in adobe reader) has the description, and the pages following it have the wiring diagrams for the electrical box for 115/230 volt systems.

          Need to know what the color code is for one side. Old units are marked on the wires. Replacement not so much.20161031_195345.jpg

            So you need the wiring layout for the black wires on the new units?
            What voltage does your machines run at?

            They *should* be labeled on the black wires in white lettering, really small numbers.

            If not, flip both transformers over to the bottom and compare where the wires come out of the windings. Mark them as closely as you can, then grab a multi meter. Set it to a continuity test (if you don't have that, you can use ohms and check resistance).

            H1 and H2 will show a closed/low resistance to each other, H1/2 to any other leads will show open/infinite resistance.
            H3, H4, and H5 will all show closed connections or low resistance to each other.

            Using the ohm setting for resistance, H3 to H4 will show a larger resistance as compared to H4 to H5.
            H3 to H5 will show the largest resistance value, which will be close to the H3/4 + H4/5.

            Please keep in mind that these values are while the transformer is not connected to anything!

              All the H wiring is marked. That's an easy match, the opposite side not so much. If you look at the pic, the winding is covered. When I dig a little deeper. I find that the wires aren't visible coming out of the winding. There's solder tabs arranged at the edge of the winding, so I can't follow them in.

                You're right, I haven't seen a transformer like the one already installed. Interesting.

                Just trace where the wire from the transformer goes to and then reference the schematic to figure out what the color should be.

                Attached is a 230 volt schematic with the wires you should check, colored in.

                The wire going up to the fuse in the upper right corner is your yellow.
                The one going to TS2-6 is your blue (kinda looks green)
                Orange is taped/capped off.
                The final wire going to TS2-4 is the tan.

                If you have a 208 or 115 volt system, you'll need to check the manual for the correct schematic..

                  From what I see in the picture of the transformer, and the grey wire around it, I would say it is a Jap electrical box.
                  Doesn't really make a difference in wiring in a new transformer, just an observation.


                  Now that I think about it, it would make a difference because on the Jap machines the deck light was wired to one of the connections on the high voltage side of the transformer. So in wiring in a new "Universal" transformer the wires for the deck light would have to be moved so that one wire is connected to one of the points on the motor contactor and the other to either F or G on terminal strip 1 along with H2 or H3.

                    COBALT TO THE RESCUE !!!

                    That's exactly what I needed !!
                    It's like trying to put a Ford wheel on a Toyota...
                    Our pit lite is wired thru a relay (115) which energizes the motor relay (230)...Dr. Frankenstein would be scratching his head...

                    Thank You !!

                      Awesome, glad I could help.

                      I have a strong background in electronics, so I try to put that to use wherever I can. Feel free to ask if you need anything else.
