Taxi: jet bumpers have stopped working

[Joyride]

All three jet bumpers on my Taxi stopped working tonight. I've got the original manual but I'm struggling to see how you correlate the list of fuses to the circuit they operate in.



Any suggestions on how to troubleshoot this?

Quick google on rgp suggests one of the 2.5A slow blow fuses F1, F2a, or F3 on the aux power board covers the bumpers (+ other solenoids ?? ). Check these.



Also check there isn't a fuse under the playfield for the pops, I think some Sys 11 games had one.

Had to get Andy Netherwood round in the end. He nailed it straight away - pop bumper switches were working but the bumpers weren't firing. Andy traced it back to a dodgy transistor on the main board. He nipped out to his van, grabbed a new transistor and within minutes had it soldered onto the board; problem solved. It was fascinating to watch.
