hello
i was removing the lower playfield in my gottlieb haunted house to clean it and i think when i set it down i bent 2 of the contacts on the one target that is attached to a coil. when i powered the game back on and put it in test most to test the lights (which worked and which ones were burnt out) this coil fire 2 times.......then about 1 minute later this coil started to smoke slightly. i put my finger on it and it was very hot.
NOW when i hit the contact associated with this coil, it gives me points like normal but the coil wont fire. it acts like it wants to fire but it wont (it moves very slightly) when i try to move the metal cylinder inside the coil its really tight and wont move.........im guessing that coil is now burnt and im going to need a new one?
 
yep, you let the smoke out. Replace the coil. When you put it back in be sure and check the transister that goes to that coil, chances are you burnt it too, and if its bad as well itll fry the new coil. Easy way to tell, put the new coil in, turn the game on and watch to see if it locks on. Turn off immediately if it does, then replace transister
 
The coil will need to be replaced if you cannot get the sleave to come out. Generally speaking if the coil sleave (cylinder as you referred to it) is stuck in the coil, the coil has overheated and warped. Be certain that you correct the problem that caused the coil to lock on, because if you do not, you will burn up the new coil too.

Pinball Resource will (most likely) have the coil you need.
 
will i be able to tell if the transistor is bad by seeing if it is burnt on the board? i dont know if it would be bad or not, because when i touch the contact together (like it should work) then it the coil will pulsate as if it wants to fire/work. if my transistor was bad would this coil even move at all? or would it be stuck on all the time? thanks for your help guys
 
You can test the transitor with a DMM, but it is just as easy to put a new coil in the game, then turn the game on and see if the coil locks on. If it locks on, then you likely have a burnt transitor. Assuming the associated switch is not stuck closed. Either way you have to replace the coil. If the coil is locked on, then simply turn the game off and you will avoid toasting the new coil.

The kicking targets are not computer-controlled solenoids, so there is no associated transistor. The switch closing provides voltage directly to the coil. A seperate switch is also there for scoring.

yes darren that is how this looks. Im going to have to call and order another coil here. Thanks for the advice!
