Pinball Magic
Capcom, 1995My PM has started blowing the fuse at F9 on the power board. This fuse powers the magic wand magnets. Currently the wand coils will magnetise and levitate 2 or 3 balls and then the fuse pops. If anyone has any ideas what could be the issue i would really appreciate it. Ive checked the coils and they seem fine and from what i can tell the transistor driving the coils is fine as well.
Thanks,
James
Replced the transistor and the fuse still blows while carrying the ball down the wand. Retested the coils and theyre both coming out at 12ohms. Then i tested each diode across both of the coils with one leg out of circuit and one is testing at 690 and the other at 710. I reverse the DMM leads and both diodes read 1. Im using a super cheap backup multimeter at the moment so im unsure about the readings.
Whats your thoughts?
What voltage do you have going to the coils? Any chance there is a short in the wiring going to the coils, perhaps from the motion of the wand (I've never really dug into that wiring part of the game, it's just a thought)?
Quoted from JReedie:Took the wand assembly out of the game and gave it a good clean and look over, replaced both coil diodes and shes now working perfectly again!
Thanks for following up.
