    Hey guys! First post here. I acquired a captain fantastic machine the other day and I'm fairly certain the transformer is toast. I'm getting 110 to it and 0 out of it. I removed all fuses to isolate if and still got 0 from it. Am I correct in my thought that it is in fact dead? And, how would I go about getting a new or refurbished one?

    #2 12 months ago

    That does sound like it's dead, but are you sure you're measuring correctly? Can you post a picture of how you're measuring, etc?

    #3 12 months ago

    Using a fluke mm. I'm getting 0 off of every leg I'm going across. I'm not home right now unfortunately. Still thinking about it though. Driving myself crazy. I have no power anywhere when I flip the switch to turn it on.

    The full schematic is on ipdb.org, but this part might help:

    Blown transformers are very uncommon. With the game UNPLUGGED, can you measure any resistance in the primary winding between lugs 1 and 3 (assuming you have the 115 volt transformer)? How about the secondary windings (between lugs 2-8, 4-8 and 8-10)?

    Yep that's what I was going off of. I measured every spot on there and came up with nada. It's the 115 setup. I thought that maybe I could have power draw so I pulled all fuses and check the transformer again. Still nothing.

    #6 12 months ago

    You did measure for 115VAC on the transformer input lugs? It sounds from your previous post that you see nothing anywhere and that something is pulling the 115VAC down to 0 on the input lugs.

    #7 12 months ago

    Yep. I have power going to the transformer but nothing at all coming out. I thought maybe it could be possible I had something pulling it down but even after removing all fuses, still 0 coming off the transformer.

    #8 12 months ago

    As Mark questioned, can you get a resistance measurement on the primary 115VAC winding and the output windings identified by Mark. Make sure the machine is unplugged from the wall.

    #9 11 months ago

    43k ohms on the 115 side. Jumps all over on the output side. up in the hundreds though.

    #10 11 months ago

    Rechecked it. Was on a dirty spot apparently. I'm getting 17k on the 115 and 20k on the output side. I'd say she's toast

    Question is now do I get a new one?

    #12 11 months ago
    Quoted from Sparkplug1:

    Question is now do I get a new one?

    Don't forget the 2nd (and very important) question: Did something in the pin go bad, causing the transformer to fail? First check would be to look at the fuses for proper ratings (i.e. Did someone put in a higher rating fuse, causing the xformer to fail instead of blowing a fuse when something went south?).

    Toasting a replacement transformer would be an expensive lesson learned... As MarkG mentioned above, transformers have a low failure rate. They are just wires and a core...not much to go wrong. Not impossible tho.

    #13 11 months ago

    I'm not sure of the life it has had. Bought it from a guy who said it didn't power on. I have one fuse that has been replaced with a 15A. Should be a 10A

    #14 11 months ago

    Which version do you have? EM or SS?

    Quoted from mbwalker:

    "Capt. Fantastic" is an EM only. Unless it's the dopey home version.

    #16 11 months ago

    PM me tomorrow or Monday and I'll see if I happen to have one around. That is a fairly common transformer in Bally machines so I might have one in the garage.

    Quoted from jrpinball:

    Only asked that since ipdb.com showed both versions. But after revisiting, ipdb doesn't show any qty for the SS version. So I bet your comment is right. Just double checking!

    This is one of the fuses that protects the transformer. If it was 15A, then there is a chance that the transformer might have been damaged if the pin had a short somewhere. So was that the fuse that should have been 10A?

    I did notice the other two are 15A. Were those correct?

    With the pin off and unplugged, remove the fuse and use an ohm meter to measure the resistance between these two points.

    I don't know what would be a good reading, but someone on Pinside should have an answer.

    Can you post a photo of this transformer and any nameplate info? Might help finding a replacement...

    Numbers are right on the side of the transformer (on the paper wrapper)
