We’re troubleshooting a Spanish PinBot clone (i.e. Cirsa PinBot). It was working when we got it, but abruptly none of the side ‘A’ solenoids work.

We’ve found the A/C relay on the underside of the playfield and it appears to produce green flashes from inside the relay when it switches when we use coil test 14 to test the relay. The relay appears to click and something inside of it moves when we switch between the ’A’ and ‘C’ sides during the coil test. The ‘C’ side flashers all work.

We’re using a PinBot (Williams) manual off the internet and some general Wiki sites on System 11s to trouble shoot. We’ve checked all fuses and replaced F4, which had blown. It’s similar to a Williams PinBot (we checked that before getting it) so advice related to PinBots and System 11 should apply.

Any advice?
