Finishing up an LED swap on my routed Whirlwind player's machine. Not a gem under the playfield so as you can imagine it's always possible some wires may have moved in the swap.
I of course turned the game on a couple times to test and saw the "pinball missing" message and thought nothing of it, after all the 3 balls had been removed.
I also decided to replace the Rottendog power board with the stock power driver board I removed years ago when it was blowing fuses on the hopes the LEDs would play along better. The Rottendog board had caused a hum so loud through my pinball pro that I thought the machine would explode (all grounds checked).
Power board in, game on, hum gone! Aces! Except...3 balls loaded..."pinball missing".
Checked switch edges and sure enough, trough 1 and 2 switch levels register as down, trough 3 does not. Despite 3 balls loaded. These will be tough to test with the playfield up, anyone happen to have seen this before and know the common cause? A quick glance and all the wiring down there looked in place (not any lights in the trough to really mess up the wiring).
I will, sad as it seems, switch BACK to the noisy Rottendog board as well to make sure I am fully undoing and checking all things I changed for a pattern. If the RD board resolves the problem, I suppose that tells us something is not good on the stock power board despite it no longer blowing fuses (I was giving BR1 the side eye).
Here's the worst part - I tried playing a game anyway, figuring OK, let's at least see it still plays thinking it's only got 2 balls loaded, and man did the game act WEIRD. When I drained through the outhole the game didn't end the round (as if there was a stuck ball) and the spinning discs and fan went into like OVERDRIVE MODE -- like they were going to spin off their places! I'm talking like, Johnny-5 struck by lightning overdrive.
Additionally, the spinning discs seem to have developed a weird stutter during attract mode where they will eventually start to stutter-spin up on their own which I don't believe ever happened before.
Anyway, all sorts of ghost in the machine weirdness I seem to have introduced by swapping in LEDs and putting the factory driver board back.
Just curious I suppose if anyone's seen anything before they may be able to set me off on the journey on. I am a very amateur tech though I rebuilt my first molex the other day and that made me proud (board work and soldering under the playfield still make me shudder).
Is it possible that the Trough 3 switch just died right at this exact moment? I didn't get near its wiring and it worked without fail before I finished this lighting swap. I figure that might explain the ball behavior but still not the weird machine behavior.
