So today I thought I'd clean me balls (quiet Dan) lol and give the of a quick clean and check things over. Need to adjust the sling switches and right pop switch. Thought I'd go thru all the tests and in the flipper tests the upper flippers hold fine but the lower 2 the left u can see tries to move but the right nothing but if u lightly touch them they do it. But in game the both work [emoji53] any ideas? Could I of done something up to tight when I originally serviced them or is it likely to be electrical like a transistor or something?

That's odd that it works in game, but not in test. What you have described, the hold transistors are firing ok, but not the power transistors. I would have thought that Daz was on the money and it was going to be down to a coin door interlock
 
Are your EOS switches working correctly? I just thought that in game it will compensate for bad EOS switches automatically, but maybe not in test?

Are the swithes NOT shorted when the flippers are in their resting position?

And if you manually move the flipper bats up in switch test, does it report the EOS closures correctly?
 
What you describe sounds normal to me, hold coils for holding, not lifting the flipper from its home position. If I've read that wrong sorry, I've been drinking.

You have indeed when it does the hold test it activates the flipper and holds it in the up position

Yeah they work in switch test even just adjusted them so they are more sensitive to no avail. Looks like the right one is slightly weaker when trying to do the hold test to
 
The machines I've tested flippers on just twitch the flippers during hold coil test as the weaker coil attempts to raise the flipper and completes the action if raised manually and holds. I haven't run the test on a TZ though.
 
Just tested Shadow, TOM and BSD, all exactly the same as you describe during flipper test, first test fires main coil, 2nd test fires hold coil only which may or may not raise the flipper depending on how powerful your hold coil is. On BSD it barely raised the flippers but just about about managed it. On shadow and TOM the hold test only managed to twitch the flippers unless I manually lifted the flipper and then they held. Door open or closed made no difference.

Again, I haven't tested a TZ but I doubt it's any different.
 
And from what my shadow used to do in that test none of your machines sound right

Should be like this kev

First is flip second after the beep is hold

I have a tz. Currently working fine.

I ran the flipper test for the first time in my life for you. With the coin door open. It flicks up the flippers as you would expect on the power coils. It repeatedly fires them individually every second or so

When you advance to the hold tests, the lower flippers barely tremor but do visibly move up a few mm, again repeatedly every second or so

The upper flippers barely flinch in the hold test

That is showing just the hold coil firing Rudi, it isn't firing the main coil at all. It just so happens that the hold coil on that upper flipper ( which has less resistance to flip in the first place ) is powerful enough to raise the flipper, it's visibly less powerful a flip than the first few flips before you advanced the test to the hold test.
 
Rudi, I think that if the flippers work properly when you play the game, forget about it. I think all is well.

Hmm very confusing the way the upper one in my vid behaves in the test is the same as the shadows lower flippers used to do it. Which is what led me to believe something was amiss cuz when they didn't do that in test was at the slam when it had blown transistors.

Odd tho ain't it how everyone else's acts differently

It's just that the hold coil is barely capable of lifting the flipper on its own so on some machines it may manage it ( but very weakly! ) yet on others it will probably fail completely, just twitch or do nothing unless you lift it manually.
