hows it going....i have hurricane pinball and no GI lights on playfield or back box are working and 30% of insert lights not working
-purchased the game had battery acid leak cpu board corroded 2 rows of resistors. Also a couple of the U chips underneath battery holder had leg corrosion from acid leak. game was asking to check fuse 114 and 115 upon trying to boot with new batteries and minor clean up. Which were both fine.
-installed a new cpu board. game now boots up and plays as it should no errors but no gi lights at all and half insert lights out
-all led check lights on driver board are lit up except 3 which is supposed be off
-all fuses have power and have not blown
-there is power at all of the GI lights not working
-the j115 plug had been plugged in upside down so i plugged in correct direction
-checked all plug positions on boards and wiring placement
-i put a jumper from Q12 to ground and other 5 heat sink transitors going to gi, only one string of gi lit up. figured it was bad triac tranisitors so I had the 5 replaced for GI. no change.
-following another thread talked about U1 on driver board links all the gi from driver board through ribbon cable over to cpu which controls dimming of all lighting. i've never really gone this deep but its getting a little pressure. was thinking of buying a new driver board but fear of not fixing the problem. the wiki was saying logic probe test from U1 to cpu leg
First picture shows original board battery acid damage
