ami g 200

i checked the scan switch. got it adjusted and turned the meter wheel
and it stopped the turn table so it looks to be okay. when i checked
the power on my push button accumalator theres no power. the coin
mechanism was missing when i bought this. there is a cable with five
wires cut on the lower left hand side i belive went to the coin mechs.
does it have to have the coin mechs hooked up to get power to the
accumualator from the junction box. if so can i tie one of these wires
together to get the same results.the guy i bought it from said it was
on freeplay but i dont see how it was done. also what models use the
same coin mechs and plug. i would like to find one with the plug and
about 3ft of wiring. thanks in advance.

The "G" is further back than I have delt with in AMI's I do have an
"F" original manual and it shows a credit unit typical of what AMI
used back then.

Look for a (likely) gray box approx 4in sq. take the cover off and you
should see a gear with some solenoids and pawls. Try moving that
gear counter-clockwise to add credits.

The direction may be different depending on how it was built, and you
may have to push-in a pawl on one of the solenoids to make the credit
wheel turn.

When these machines were sold into home use the a-hole operators often
disabled the coin units to prevent them form being put back into
revenue service. With AMI it is simple to "free play" by simply
moving up the credit wheel and either cutting the wire to the subtract
coil or simply moving the wiper or leaf contacts up to a point where
they are always credited.

One problem with either of the methods is that since the credit
contacts no longer move, they can lose contact due to tarnish or
pitting.

As for wires cut to the missing coin mech DO NOT permanently connect
any of them together. They are for momentary contact only and would
burn out either a coil or a fuse protecting it.

IF the wire colors to the coin mech are the same, it goes:
red=common..white-yellow-black are the various coin switches. You
should be able to momentarily touch one of them to the red and hear
some "clunking" sound in the credit unit.

As an extra comment on this, there is no latch bar solenoid or
anything on this system.

When credit is established (see my other post),
this simply enables power to flow to the motor via leaf switches on
the button banks
(note - one letter and one number must be closed to start motor) ,
which then does the
rest of the job of transmitting the "serial data" down to the pulse
receiver at the lower front of the
mechanism.


If you gently rotate the motor wiper forward (clockwise) even with no
credits and no buttons pressed, it should start running by itself,
stop after one full turn, and you should hear a series of fast
"clunks" from the mechanism, similar to the noise you hear on the line
when dialling an old rotary dial phone.

if you don't have this, its time to start checking for 28v ac.

Hi, out of interest your points are totally correct for the other
systems, but for future reference the G-200 uses a totally different
and very unique design of credit system to both the G-80 series and
the H onward.

refer to my other post.
