DX7 Battery Question---Weird
I have 2 DX7 transmitters. The batteries in one of them went dead and I built a new eight cell NICAD battery pack. (FYI, I routinely build all sorts of battery packs and have never had a problem). All the connections are fine and then voltage checks just as it should.
When I installed the new NICAD pack in the older of the two radios and turned the radio on, I got a rapid beeping sound and a blank screen. I turned it off, took the newly constructed battery pack out and installed the battery pack from the newer DX7. Now, when I turned the older DX7 on, it worked just fine.
Somewhat confused, I then put my newly constructed battery pack in the newer DX7 and turned it on. It worked perfectly. Weird. Then I reversed the process putting the new batteries back in the older radio and got the same beeping sound as soon as I turned it on.
This seems crazy to me. Both DX7s work fine on one of the battery packs, but the older DX7 will not work on the new battery pack. I have switched back and forth several times and always get the same result. Both packs are fully charged, have solid connections and the correct voltage output.
Anybody have any ideas?
