The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - Hmm. Inside turn signal indicators function differently with headlights on

the plot thickens.. When brights are "on" with headlights on, both turn signal indicators come on (and selecting left or right turn signal with the lever still gets the normal, correct response on the outside turn signals). Weird behavior. All these connection on the main harness are on the upper side of the harness plug - all wear marks on the the printed circuit look perfectly centered where they should be in the copper connections, no 'tweeners'. Hmm.
