My Twilight Zone's upper left flipper stops flipping during powerball multiball.
During other multiballs it works fine.
So I'm thinking its a power thing.
I've got a rottendog driver board installed. So should be good on that side.
Any suggestions on what to look at?
Cheers!

That's an odd one. Early rom version? Makes me think this is a rottendog board issue, but you would think it would have popped up on a TZ by now. I'd pull the driver from your FH and see if that changes anything.

The RD board should have nothing to do with which flippers operate at all.

You should check the 12VDC power supply.

TZ has a FlipTronics II board in it.
Here's some info...

Check the setting of feature adjustment "Low Line"; this option turns off the upper flippers during multiballs that use the Powerfield (Powerball Mania or Lost in the Zone).

What BCD says -
It's a ROM setting. Used for 'low line' applications (where your house/arcade voltage is below 110v), this kills the upper left flipper during LITZ and Powerball MB, to help avoid the low line resetting the game.

Awesome tip guys. I would never have guessed this to be a "feature".

I've never heard of this. The only reason I stated the board Chris was due to some strange things I had heard of happening with some RD whitestar boards.

Thanks guys. I'll check out the settings out tonight.

Yes, the low line setting was set to Yes.
I changed it and now the upper left flipper works fine in powerball multiball.
Cheers!

Way to know that!

I've heard a few odd issues with RD driver boards in TZ too...Burt never anything about flippers, which makes sense as flipper circuitry isn't on the driver board, other than power.

Was it just the UL flipper, ot was the UR flipper disabled too?
Per the manual, both should be inop in those modes.

The manual is wrong in this case - it's ONLY the UL flipper..

Any other tips for improving magnet strength during powerball mania?

I'm running a rotten dog board.

Magnets in the mini playfield?

Hard to say, but the first thing I would check is the magnet's part number. Back then, there were two different magnets available, one stronger than the other. Over the years, if they were ever replaced or removed, it's possible wrong ones were put in.

The issue is that they work fine in in single ball play, but lose a bit of a power in multiball play, with all the other coils going and being active. I don't think this is a coil issue, as if they were stronger, in single ball play they would smash the mini to hell.

Okay - I wasn't sure what was being referenced. (As, honestly, I don't notice a loss of 'fling' on the Mini Playfield when I'm in the Powerball MB or LITZ.)

The only thing I can think of is that since both of these are driven by the 8 High-Power Driver PCB, check that board - make sure the resistors and diodes and the TIP102s are up to snuff?

Is the stronger magnet 20-9247?

Anyone know the part number of the weaker magnet?
