I picked up a used AT Horizon wings and I have a question about how the battery Tender is supposed to behave. When I plug in the AC, the Tender chirps about every half second, neither indicator light comes on and the output voltage cycles between zero and about 1.5V DC in time to the chirp.
I can't find any reference to this noise online. So, does anyone have any insights as to what's up?
