Wow. I thought I was on my own w this, as I thought it to be possibly due to a previous fender bender.
SYMPTOM:My dash lights (not radio or dials lighting) will flicker or drain or almost no lighting, again only speedo/ rpm location. As stated if I catch while it starts, I can turn down the illumination potentiometer or dial and it usually holds. I have also a problem with the horn going in op ( perhaps electrically related? )
QUESTION: What/where is the wiring or junction related to the power for the dash and the interior dials? Has anyone figured it to be tied to the illumination dial (potentiometer)?
Any assistance appreciated
