Not my day. I installed a play field protector, reattached the spinner hook that I had come off when I loosened the spinner on top, switched out a few bulbs to led's and now the kicker top right near the star roll over target keeps firing when I turn the machine on in attract mode. I put a card in the switch ends to make sure it wasn't being activated from the leaf contacting, and it still keeps firing. I reseated the molex connectors on the board that correspond to the wire color, and reseated the harness connectors. It stopped for a bit ( a minute) and when I lifted the play field slightly it started again..is this a bad coil? all the wires are intact..

I would look for pinched wires and look over anything you took apart.

It won't be the coil, the coil is just "dumb" unless it gets power. Well a ground actually.

Ok. Will
Check again. Mostly the taking apart underneath were screws holding bulbs.
Aside from reatching the spinner On the top it was ball gates. But I will go through all the wires again. Strange

I had the same problem on mine. Upper right kicker would fire constantly on power up. Problem was a mangled switch on the coin door that was stuck making contact.

The coin door? What type of switch. I will look there as well

#6 5 years ago

The switches for the coin mechs. The problem is probably just a stuck switch somewhere its easy to overlook the coin door switches but they are part of the matrix.

Could reatching the spinner switch cause it? The spinner worked so I assumed that wasn’t an issue.
When I go back in will look coin door switches and all wires

You need to check the switches in the same row or column as that eject switch for shorts. Those are:

Row
Left Coin Switch, Upper Middle Left Standup, 5 Target, Right Eject Hole, Middle right standup, Ball Shooter, Right Eject Rollover

Column
Bottom Left Jet Bumper, Top Left Jet Bumper, Top Right Jet Bumper, Bottom Right Jet Bumper, Top Center Targer, Right Eject Hole, Upper Top Right Standup, F Rollover

I went back and looked at all the switches and wires listed. Jiggled everything. Nothing looked wrong and now it works. I guess that’s good? Obviously there is something somewhere that’s close to failing, maybe it means it’s nothing catastrophic though. But it’s worked now for 20 games..appreciate everyone’s input. Will Save this as reference when it happens again

You just have a short. Nothing is likely close to failing. You just need to trace the wire through the whole row and column listed above if it starts up again. One of those switch wires is intermittently shorted.

The wires are all intact, no breaks. Not to sound ignorant but .. would a short mean one of the solder connection is bad on one of the switches/connedtons. If so why does that cause a coil to fire ? Curious on electro physics if I. I just need to resolder the one, when found, that is cold. Thanks for your patience

The coil isn't locked on, so it's probably not a coil short.

The coil keeps kicking because the switch for the kickout is triggered, making the game think it needs to kick out a ball. The switch can be triggered the real way (ball in the saucer, pressing the switch) or by means of a short on the row or column that switch is on. That's why I gave you the list of all the other items in the row and column for that kickout switch.
