Hello, hoping someone can help me here. I have a Robo War all ground mods done, new power supply, Swemmer MPU and Driver ribbon cable connect. This pin was a tank for many years until recently it blew an IC chip on the Swemmer MPU, Fred fixed it and sent it back. Reinstalled the MPU and now when the Flashers are supposed to go off they trigger some of the drop target coils. When the spinner flasher is supposed to go off it triggers the outhole coil. SO no flashers, instead coils trigger. I have tested another WORKING MPU and the same thing happens. Also swapped out ROMs and you guessed it same thing happens. What is going on here?? Any help would be greatly appreciated!
Thanks

Thanks, will check tonight.
