Tech: IJ resets and turns off and back on

[Guest]

My IJ was doing this when I first got it. I replaced the bridge
rectifiers and all seemed good. Now about 20 games later it is doing
the same thing again. Turning off in mid game.
In addition some times it puts two balls into ball at the start of a
new ball.
Not sure what would cause these two things

thanks

http://www.marvin3m.com/fix.htm Clay has a reset section, if you haven't
studied it. And just because you put in a new bridge rectifier, don't rule
out a premature failure.

But first be sure you don't have the classic IJ problem. Front right switch
on the mini playfield gets hit underneath by balls. This smashes the switch
lugs/wires/diode and shorts things. This switch is on your ball jam opto
line and is most likely the cause of the extra balls, also a reversed diode
or in this case a shorted switch wire/diode could be the cause of your
resets. I'd start there. LTG
