I have gremlins in my gauge lights and headlights..I replaced the headlight switch and the voltage regulator is a new solid state from rt engineering. If i put my signal on it works fine but if i put the headlight on when the signal is on the signal indicators don't blink. I put a ground wire from back of headlight switch to column but no change. Any suggestions to help make tomorrows task of chasing down the causes a lot easier? my front fender mounted signals and bumper mount signal indicators do not come on. Thanks for any and all help....
