My 1974 A407 power light over the dial stays mostly off but sometimes gets in a tizzy and starts blinking like crazy at times instead of being the steady on mode it was meant to be when the dial is in the ON position. Its just a simple neon bulb with a resistor. Im thinking its the resistor giving the trouble. Can I just bypass it? I saved the light from my 1964 A500 but its different and wont work.
