I went to test BR3. The only bridge testing I'm familiar with is on WPC power driver board with the bridge having an offset leg. I looked at the bridges on this board and didn't see an offset leg, but saw a + and -. Are these the DC legs? if so I tested it correctly using the test method in pinwiki for testing the small bridge rectifiers on a dmd control board on WPC games (section 4.22.7) Three of the readings were in the .36 range, one didn't give a reading, I'm assuming a short. I tested the other bridges and they were all reading in the .55 range, except for one on BR1, probably should replace that one also while board is out. Can anyone tell me if I performed the test correctly?
I also noticed there was a slo-blow 5amp in F4, I replaced it with a fast blow and turned the game on, it instantly blew the F4, but not the F6 this time. I'm guessing the slo-blo 5A in F4 was like being over fused and possibly caused F6 to blow, hopefully/maybe?
