Yes all opto switches test fine.

Quoted from markmon:
First off, your test of shorting the ground lug probably only tested hold power not high power which is why the flippers raised slowly.

So if you go back into the solenoid test and test your flipper solenoids there, do they fire? Do any of your other solenoids work? I'd start there.

Also, the flipper optos are odd. If one side is unhooked then both sides stop working. In flipper test, you get 4 buttons for each flipper press? (Upper right + right, upper left + left)?

Sorry missed question number 2.
In solenoid test the flippers do not work.

In flipper test I get 2 switches closed for each flipper for a total of 4 closed if I press both at the same time.

Let me get this straight.

You opened coin door and held in high power interlock switch and things
worked ?

You released coin door high power interlock switch and closed coin door and
things didn't work ?

If so - bend the flap over to be sure it is closing the high power interlock
switch enough. And be sure the door harness isn't between the switches and
flap.

Sorry initially things worked. Then when I closed the door and played a game flippers stopped and haven't worked again.

Lloyd, he said in the first post that all the other solenoids still worked and he has 70VDC at the flipper coils, so it's not a high power interlock issue.

As for slow flipper raise, the flipper coils have two windings in parallel and so two ground points. If you grounded the lug at the non-banded side of the single diode, that's low power hold. To test high power, you'd have to ground the lug that has the junction of the non-banded and banded diodes.

Only take seconds to hold that interlock in with a finger and try flippers.

He didn't say what position coin door or interlock switch was in when he gets 70 volts.

And that switch can do funny things when not fully compressed.

You may be right, but I like to keep ruling things out.

Agreed

Just for clarification:

The Flipper Opto board is working because you see the switches register in test mode?

The 70V was measured at the coils with the coin door closed?

All the other high powered solenoids (not just low powered) work with the coin door closed?

If all of the above are true, try powering off and reseating the cables (as taken from Clay's guide):

Re-seat the ribbon cables going from the CPU board to the Fliptronics board (be careful to not mis-install the ribbon cable). Some flipper confusion can be caused by these ribbon cable going from the CPU board to the Fliptronics board, and reseating the ribbon cable often clears this problem.

Flashers too. Those guys are the ones that usually stop if the switch isn't fully depressed.

Ok Reseated all the cpu board cables, and ribbon cables. Bypassed the interlock switch, and then while testing the coil lug on the flippers blew fuse 116. Replaced that, and retested, and guess what... Flippers work now.

Not sure which of the above got it working. Thanks for all your help guys
