Hmm, I seem to have a related issue, maybe the experts could chime in.

on my World Cup Soccer 94 everything works fine, but both flippers flip once when I do the "Lamp + Flash" Test - anyone come across this before?

thanks!

So, a little more background (yes, I am a SS newbie, be gentle)

Measured 12v at TP3 and it fluctuates wildly between around 8v and 10.5V

Given this 12v I believe is derived from the 18v circuit I tested TP8 and it also fluctuates wildly between around 12.5v and 14.5

In between the transformer (via J101) and 18v I think is BR1 and two Caps.

I searched pinside and found this test of BR1 from zaza
0442be088c9961a219faafad7b4d73489889d49d (resized).jpg
My readings are:

1 - .437
2 - .874
3 - .447
4 - .446

Does reading 2 indicate a failed bridge that would cause the above symptoms or have I jumped to conclusions far too quickly?

thanks, all!

Many thanks zaza

Replaced BR1

Reading at TP3 is better; fluctuates between approx 11.2 and 12, averages around 11.5

TP8is higher at 14.5 to 15

Game "appears" to playing ok - do I need to worry / do anything more?

zaza it measure 7v at both 4+5 and 6+7 (and 3.5v at 1+2) ???

Saying that, the machine plays well - as far as I can tell!

Any idea what is going on?

Oh. Ok then I get 13.5v

(It's been said before but zaza your pictures are brilliant!)
