Hey Mud - the Voltage gauge on my dash of my 1989 FJ62 has recently started pinging to the top when cruising at highway speeds. When it happens, my stereo cuts off briefly then comes back on, but no stations or memory loss. Truck cranks and drives fine at lower speeds (and no radio issues at low speeds), and voltage stays at 13.5 at lower speeds. Gonna check the battery and alternator but any other ideas?? Thanks!!
