Is the machine is Self Test or Run mode? The SERVICE switch on the

(Selection and Credit Computer) should be off to Run mode.

Hi John,
Thanks for the great resource that is flippers.com and taking the time
to respond.
-Verified SC&C is in Run mode. I can enter service mode and run some
of
the tests successfully although tests that apply to the CD (keys
7,6,and
9) produce no results.
Also while in service mode the gripper keeps grabbing random CDs from
the carousel, placing on the player then returning them after 4 or 5
seconds.

Are the Z and K LEDs blinking when the carousel rotates? Read about
that

on my page...#2-1.

-Z flashes steadily as the carousel rotates while K flashes every once
and a while.

Have you followed the troubleshooting guide posted there?

-I'm still working through all of the troubleshooting that even
remotely
resembles the issues I'm having. I'm heading back over to the in-laws
again Wed night to dive back in.

If it is a CD player failure the CD would be placed on the player and
the machine would wait ten to twenty seconds - then return the CD to
the

basket if it couldn't access the player. If it puts it back immediatly
then something else is wrong.

- I timed the delay between placing the cd on the player and returning
it to the carousel and it came in between 4 and 5 seconds so a far cry
from 20 seconds.

Thank you again for your help especially knowing that you are swamped
right now.

One thing to try is unplug the battery jumper and leave the machine off

overnight. This will flush the memory and will sometimes cure weird
problems. Plug the battery jumper back in after you have turned the
machine back on...

"Old pinballers never die, they just flip out."

I just got back from round two with the OMT. I pulled the batt jumper
yesterday so it's been unplugged for the better part of a day. Powered
up the machine and plugged the jumper back in with no change in
symptoms.

The juke still flashes 8 on display, cd drive still flashes 0-1-8,
gripper arm still grabs about every 10th cd, places on the player then
picks it up, returns it then the carousel spins ahead another couple of
disks then repeats the whole cycle.

I followed the troubleshooting in Chapter V, symptom 2 for permanent
gripper arm movement. Troubleshooting suggests if the gripper arm
movement stops after pulling BLUE (ours stops when blue is pulled) then
the SC&C is running out of program and suggests computer is defective.
I also checked pin 4 on the BLUE plug when k6 is open and only got
-.412v insead of -30v the manual specified.

I checked voltages at the following fuse locations on the 40210 amp just
for GP.

Si6 + 28.9v
Si4 + 33.9v
Si5 + 10.5v
Si3 - 34.2v
Si2 Zero
Si1 Zero

And here are some pictures of the 40210 amp and the CDM41/CDM12 SC&C
just in case someone can see a glaring error in the wiring.

Thanks again John,

Can't help for a few days. Will review this over this weekend and see
what further steps I can advise...

A quick thought is to check that the microswitches all show zeroish
resistance when closed (power off, computer unplugged) and infinite when
open on the off chance that either the K7 or safety micro switch are
defective.
