Radio was having issues. Both Radio fuses were blown (#2 - 15 amp and #12 - 10 amp). Radio worked but then there was some hum in the speakers (grounding issue). Removed head to see if any issues there. Unplugged everything to check for exposed wires, etc. Plugged back up and now no power again. Checked fuse #2 (okay) and #12 (blown). Would the grounding issue cause this to blow again? I just put it in yesterday.
