I install a RetroSound radio in my 49 a few months ago. Finally got around to wiring my it up. I followed the instruction and it won't come on. Per the instructions I have the yellow wire coming from the radio going to a constant 12 volts on the fuse block acc 12 volts. I have the red wire coming from the radio going to ign on the fuse block. I tested the acc with a test light and it is always hot. I tested the ign on the fuse block and it's only hot when the key is on. There is a fuse on the radio and it's good. I took the yellow wire that is a constant 12 volts and ran it straight to the battery to make sure I was getting the proper voltage. I got nothing. I don't have the speakers or the antenna yet but didn't think I needed them just to see the radio light up. I'm I wrong about that? Either I'm not doing it right or the radio is bad.
