I just finished my new Tamiya Pershing. After plugging in the battle unit, it doesn't work on the self test (switches 1 and 2 in leftmost position). I shoot at the white wall all day, and no hits. Any ideas? I'm stumped...

FYI, I installed the battle unit LED emitter in the gun tube and did not install the flash unit or the mg LED. The battle unit LED is right at the end of the gun tube where the flash suppressor attaches. I have triple checked my wiring, and it all seems to be correct.
As to the tank, it works great, drives great, recoil, sound etc., so I don't suspect any DMD problems.

Any suggestions or questions would be very much appreciated, otherwise, I'll have to email Tamiya and do it the hard way.

Thanks Everyone.

Jeff.
