Hello all, just wanted to say Hi as this is my first post here.
I need some help - POA in Indy - Not working as supposed to. During test - result is OK but then when it should be moving left and right - no movement at all.. Sometimes a little bit but no more. During turning on the machine - it moves normally left right (as well as idol head)
Then - when the ball hits POA - I can move the path left and right (but RIGHT moves way way slower than left) with flippers. Optos near the flipper buttons were echanged and that did nothing. Motor when I take if out of the gearbox - is working OK (to be honest VERY VERY FAST and then it stops)
also bottom part of the mini PF doesn't light up at all (even though I have exchanged the bulbs there)

Any help ?

Its one of two things, the optos under the mini pf or the flipper optos. Thats the best place to start.

Clean all the optos under the mini play-field and the flippers. Could be a cold solder joint too, you may have to swap out the optos as they do fail sometimes. If that fails...

Marco has the motor/gearbox assembly for 58.00

I would buy one anyway if I were you, I dont assume this parts will be around for ever. I have an extra in my parts drawer.

yeah but the problem is that it is moving properly when I turn on the machine (so engine should be ok) and then during play (only right is slower than it should be). Test doesn't give any errors "POA is working correctly" but after that when the path should move left/right - continous test - it doesnt move at all OR just a little bit
strange.
Is there any way to make sure what is wrong ? (i just exchanged the optos, and now motor with tranport will be way over 100 USD and if it is not that - i will shoot myself in the head
maybe the clockworks in the gearbox?

Ok, try to figure out why you have no current to the lights in the lower part of the mini-playfield first.

It sure sounds like a bad opto to me. I had bad flipper flutter and the mini playfield was stuttering, I changes the flipper opto and all was well.

optos exchanged for a new set - nothing has changed

Which optos? The optos under the mini playfield or the flipper optos? I had the same problem and bought a replacement board, and it solved all my problems.

Flipper optos. both of course.
I will try to clean the opto behind the POA maybe that will help

It's the POA opto. I had the same problem. Replace the opto board for POA and you will be set.

I had a similar issue years ago on my IJ. I cleaned optos, even changed the opto board with no effect.
Not sure why, but I dropped in a new control board and it hasn't gievn me trouble since.

What opto did you end up replacing to get indi working again? Flipper Opto A-20207, Opto A-16657 Under the mini play field or Opto A-15946 under the main play field?

Thanks Troy
