I have a question about 3rd magnet on TZ.....

Hey everyone.
I just installed a 3rd magnet on my TZ with a NOS Pinbits 3rd magnet kit I bought about a year and a half ago, everything is well connected and works, the spiral mod grabs the 3 balls on all 3 magnets, only at multiball the game does'nt grab the 3 balls at start, do I need to adjust feature number 50 at "NO" to get it to grab the balls?
Thanks for the feedback, I only did a 3rd magnet job on another TZ and that was 15 years ago, I don't remember how it was activated, or maybe I'm missing something else???

Thanks anyway but I found my answer on Pinside, here's what a member told me for those who want to know:
"The game will *only* grab all 3 balls at start **after** powerball mania is played. (The game needs to know the powerball is locked in the gumball machine). Memory of this is reset every time the game is power cycled. i.e. you can play powerball mania, do the 3 ball catch trick, shut the game off, turn the game back on the next day (despite the powerball still obviously still locked in the gumball machine), and the game won't do the 3 ball catch trick until you play poweball mania again."

Tried it manually with glass off, multi-ball 3 ball grab works only under certain circumstances, there has to be only 1 ball in the lock area, the second ball launched has to acheive the orange skill shot and multiball must be started from the main ramp shot only, and added to those conditions, the game has to know that the powerball is in the gumball machine, so, powerball mania must be played first.
With all of those conditions, 3 ball grab before multi-ball makes it a rarety on the game and that's why I could'nt see it while I was playing.

Correction, The orange skill shot does not need to be acheived to start 3 grab multiball but everything else is correct.
