Is it normal to be able to start a game without any balls in the trough?My game has no credit dots and is playing the 9.4home rom version.Other games will say ball is missing.

Are there any balls up in the lock trough still? They might not be kicking out after the end of a game.

Can you do a switch edge test and test the trough rollovers? There should be three of them in there.

Donno if it helps but when my machine is missing a ball it will start the game but then proceed to look for the balls. Never tells me one (or more) are missing.

Quoted from bballfan:

Nope.
In fact, in a normally operating game, it's impossible.
Think about it. The last ball of the previous game must drain to the trough for the game to end. Therefore, there will always be at least 1 ball in the trough.

And, at power up, TZ rev 9.4h (at least) ejects balls from where ever they are locked (excluding the gumball machine) so three should end up in the trough.

Hope that helps.

Here's what mine does with any number of balls out of the trough

Is that what you mean ?

I bet he's lost track of how many balls are in the game. Or maybe he has a broke subway diverter. Perhaps someone should tell him how to count them all (I don't recall).

There should be two visible in the gumball machine(because the third is in the base of it, ready to be dispensed) and three in the main trough, totaling 6, five steel and one ceramic.

There are ways in the test menus to empty the gumball machine and you can just pop out the ones in the trough yourself. I say empty the machine manually and manually feed the balls in yourself to let it reload itself. It might just show you where it's not sensing the balls.

I always start with 1, then 2 ..sort of goes from there ...

you can enter test menu then go to #19 (i think, just hit left on menu buttons) Eject balls
remember to close the coin door for high voltage coils.

Yeah I can start a game with all 6 balls out of the game.

My game starts with no balls but will ball search after a few seconds.Maybe my cpu isn't working 100%.

The problem is probably not your MPU.
Get a diagram of the switch matrix for TZ.
Find the three trough switches and note their location in the matrix.
Place all three balls in the trough.
Enter switch test.
Are all three ball trough switches closed?

Now...remove all balls from the trough by manually triggering the kicker that serves a ball. Be careful...that coil has 70V at it's lugs.
Now are all three ball trough switches open?
