I just upgraded to all LEDs last night on my Getaway HS II. I first did the backbox, then flashers, then GI, then Inserts. When I completed all the flashers I turned on the machine and ran single and all flasher test through the test menu, and everything worked great. So I proceeded on for a couple of more hours doing the GI & inserts, and tested them successfully. When I put the game back together, I noticed the flashers weren't working. Went to test them and all of them are dead, and I can't figure out what is wrong at this point.
I've tested all fuses for resistance that I can find in the backbox and everything checks out. I don't see any pulled wires from any of the lights, and all of the connectors look good. I haven't had much time to diagnose further, and not even sure check connector(s) on the mainboard supply power to the flashers. Also, while I thought highly unlikely that all flashers would blow out, I replaced several with known working bulbs and still do not get any illumination from any of the 18 in the pin (neither backbox, toys, or playfield). All other lamps are working correctly.
Any help pointing me in the right direction is greatly appreciated.
