First, run through the coil test and list those not working. It would appear at first glance that something is wrong with this L/R relay circuit....it directs 32VDC flasher power to different flashers in the game. Make sure item #10 L/R relay works in coil test.

Each of the flashlamps I believe has a board under the pf with a 5ohm 10 watt resistor on it like the early system 11 games. These resistors like to fall off the boards and that disables the flashlamps

no, not the case at all. You did check the bulbs first right? Take them out and visually inspect or run a meter on them (not in the socket, they will test good in the socket even when bad)

There should be two tests for all of the coils from #1 to #8 if any of the flashlamps work in those numbers then the relay (at #10) should be OK.

shows pictures of the resistor boards under the game. Each board should have a 5 ohm resistosr and a 330 ohm resistor. The 330 resistor is not needed and if missing is not important. However if the 5 ohm resistor is missing the lamps won't work.

Double check all the bulbs, these were rarely replaced by ops as they burnt out and it's not uncommon to have 75% of these bulbs burnt out when shopping a game.

OK ....good find. Now to fix the green shield, first find out if the power (DC volts) is making to the flasher. If it is, then the problem is with the grounding circuit. Look on the solenoid table for the green shield, and ground the tab of the appropriate transistor number with an alligator clip lead. If it doesn't turn on, then you have a connection problem between the transistor and the bulb....could be a connector or a broken ballast resistor for example. If it does work, then it could be the driving transistor or something further upstream.

They don't share a coil. Flashers are considered as coils. You will find all the flashers listed in the solenoid table in the manual. There you will find important information for the flashers such as wire colors, connector locations and triggering transistor numbers

Dustin,

use a VOM to see if 32v is getting to one side of the flasher. Follow the other side to the 5 ohm resistor. Ground the other side of the 5 ohm resister and see if the flasher comes on. If not, look at connections or a bad resistor. If it comes on, follow the wire to the D15 diode pack. Again, on the other side, ground the line and see if flasher lights. Same here, if not working, check connections and replace open diode if that is the problem. If it lights, trace line to the CPU Q45 driver. Ground the tab there. If it does not light, look seriously at the connections on the board. If it does light, then it is Q45 or the drive to it.... probably need to have someone check and change that for you if that is the case.
