Tech help for shuffle alley

I have a United Altair machine I have spent over 50 hrs trying to get
the game up and running correctly. I have worked on about 5 other puck
bowlers and numerous EM pinball machines. He is my dilema. The main arm
the resests the relays always leave a few that don't reset. Meaning as
you face the game and play, the pins will pop up as normal and you
slide the second puck and they pop up correctly then the game restest
the pins all work just fine but in reality the arm didnt reset and lock
in all the relays. I have cleaned and adjusted every contact2-4 times
(depending on which one) I have removed the relays and
strainghtened/bent the metal plate that locks on the little tap that
holds it in the locked position, I have added tape on certian areas of
the bar the put more pressure on certain relays, No help, I have
strainghted the main bar, replaced the coil, lowered the coil on the
rod, Im out of ideas. Is there some type of EOS (end of stroke)switch
that turns off the main coin? It just "hammers" on and off and seems
to be to quick and won't let the relays set that fast. Do anyone have
any idea how I can tweak this machine or know someone who does? Thanks
a bunch. Billd

I would assume that the main reset coil is 120V since most of them
were. They needed the extra voltage for the power they require. I would
check the connectors to that supply to make sure you don't have a
problem there.

I would also check the schematic to locate what contacts are moving the
reset arm. Some games identify the 120VAC contacts since you can get
quite the poke from them if not careful. The score motor might activate
a relay which activates the arm.

Try and bend the contacts to allow the coil to stay activated longer.
Clean the contact pitting with a file since they are going to be
tungsten for that voltage and power requirements.

Cleaning the moving parts is the next step to assure they are moving
freely and not eating up power by binding or something like that.

There is no EOS on that coil. Just the score motor closing a circuit
for a short period of time. Crack out the schematics. Should not be too
hard to find. Don't over think the problem.
