I have a Williams 1973 Gulfstream and the pop bumpers don't fire when hit by the ball although they do light up if the right drop target is hit. Also the two kick rubbers near the flippers don't fire when hit.
I presume this is something to do with the DC power to these 5 items but I don't seem to be able to find why. All the fuses test ok and I changed the the bridge rectifier with neither the new or old rectifier making a difference.
I have pics below of the offending items and any pointers would really help, I have ordered the schematic and instructions from Pinball Resource but I impatient to try to fix it asap!
