I am having a coil issue on my simpsons game the kickback coil stays activated when i powerup the game.

Do i have to replace the coil?

Any suggestions? Thanks.

Does the coil looked fried? Check the transistor if it's not.

Coil is probably fine since it's engaging at start up. Most likely the large transistor on the driver board is shorted causing it to engage. That's what I would start with first. Good luck!

Yes, I would guess you need a new coil and Transistor. Do em in pairs.. Save time and money..

The Transistor is bad/shorted,Test the TIP36 Transistor on the PPB board and also test the driving TIP102 on the CPU board that connects to this TIP36.It's always recommended to test both the TIP36 on the PPB board and TIP102 on the CPU board.MM set on diode setting,Red probe on metal tab and black probe testing legs.A .4 or .6 reading should be seen.

That's correct,Change them all out at the same time.
