I checked the emitter with a digital camera last night, and am getting a blue light when the cannon fires, so I am going to say that it works. I tried my T1 apple in the Pershing, and it doesn't work either. I know the T1 apple works, because I have used it in the T1 for past battledays. I'll double check the pershing apple in the T1 tonight. I double checked the plugs, and my plugs seem correct. I'll double check the locations of the tbu plugs and list them in my next post, just to be thorough.
