At a loss at this point. After working well last week and then blowing a couple of fuses I am no longer able to get the communications transmissions test screen to fire in test mode. Nothing else has changed but the next time I turned it on to start working on it, it didn't work. We replaced fuses and I have tested the solenoid diodes/resisters and all are good. We noticed last night that the new MPU board light test is only flashing an initial flash and then 5 additional flashes which is 1 or 2 short of what it is supposed to be doing with a long pause between the first 3 and the final 3. Any thoughts? My next step is going to be to put on all new connectors but want to see if anything has any thoughts first.
