    I’m having an issue with the left flipper coil in my 4 mos. old Stern Iron Maiden.
    As you can see in the video, the flipper is triggering randomly and all by itself. You’ll notice the upper/left flipper is not affected by whatever is going on. I have zero experience with these Spike machines. Any ideas? And is this covered under their warranty? It’s a 4 mos. old HUO machine.

    Thanks,
    Mark

    Pertinent question:

    Have you recently installed any dumb mods involving alligator clips?

    #3 4 months ago

    Yes. A light but on the other side and connected to a GI light.

    Just a hunch, try disconnecting that mess and see what happens. I have a friend who had the same issue after installing a light dimming mod or somesuch.

    If it isn't dumb alligator clip mod related, try calling Stern's help line. Whether or not it's "under warranty" they'll likely help you, you've only had the game a few months.

    OK.
    I'll see what happens and report back.
    Thanks

    It made no difference.
    I read a tech sheet that said it could be a diode failure?

    Call 1-800-KICKERS and ask the Stern guys what they think.

    Did you check the gaps on the leaf switches? Most likely, they are gapped too closely.

    I would assume it is a double leaf switch flipper button switch. Likely the one that flips the lower flipper is too sensitive and needs to be gapped a little more.
    You could stick a credit card between the contacts and see if it stops flipping to see if it needs more gap.

    There are two leaf switches under the sling plastic, almost certainly one or both of them are gapped incorrectly. It could be at the flipper button too, like you said, but I’d bet it’s the sling leaf switches.

    Edit: ignore my post, it's not relevant to this issue.

    Why would the sling switches affect the flippers? The slings don't appear to be firing.

    Take the flipper rubber off and see if it still happens. If it doesn’t, it’s your leaf switches.

    Good point. I thought this was happening in attract mode. Could be as simple as the flipper button switch gap.

    Yeah, you are right, I wasn't thinking clearly...it's most likely coming from leaf switch at the flipper button. Apologies, one of those days of too much going on.

    I would never install any mods dependant on power from node boards even 1 led.

    Use a transformer instead.

    Thanks to everyone for replying.
    So this is embarrassing but it turns out is was in fact the leaf switch gap. This is the most obvious culprit and the first thing I checked. I checked it but never adjusted it. In my mind, it couldn’t have been this because I have played the machine off and on since I bought it in August with no issues until now.
    Any, I adjusted them and now it seems to be working fine.
    Let me also say the gap tolerance window is very small with this switch design. It will either not make contact at all or make contact by itself if it’s not exactly right.
    Anyway, thanks again to all who responded.
