I just picked up a SST and the right flipper flutters to the point i
cant hold a ball.
I've adjusted the eos switch and can now hold a ball but when holding
the flipper i can hear a slight buzzing,and the coil gets hot after a
I did order new coil,eos switches and stops.My question is=is there a
trick to adjusting them?
Is something else causing the coil to get hot?
So far ive replaced the coils,stops and eos switches and i get the
So i decided to take a voltage reading and the right flipper is not
going low when held.
Im thinking it may be the 20n10l transistor because there isnt much
else there,i checked the resistor and it checks out then the path goes
to u2 and im guessing thats ok.
This is only in the right flipper,the left goes low when held.
I checked the voltage to the flipper circuit from the bridge rectifier
and its almost 73 volts!
The book says 50 volts,is this ok ?
I replaced the rectifier and no change in the voltage.
I replaced the transistor and U2 and still no luck.
I know theres not much to the flipper system on these, im hoping its
something stupid that im overlooking.
If anyone has any thoughts i would really appreciate it.
