Tell me about your ballast resistor failure.
I personally never had one fail, even before I got my car from my grandfather in 1985 my grandfather told be the story of when it died on him.
He was on a road trip and was about a hour out and that put him pretty much thirty minutes from anything, car died. He ether was good at troubleshooting or had a reason to suspect it was the ballast. He took a gum wrapper (at that time they were foil) folded it up and stuck it between the terminals. It worked for the 30 miles or so he needed to go to get to a parts store. Years later and after i got the car I found a receipt for it in the paperwork, 1971.
