The ceramic on my ballast resistor was cracked so I decided to replace it. I purchased a Delco Remy replacement that I purchased at a local Corvette parts store. When I took it out for a drive, it started fine but would barely run. It felt like it was firing on about 4 cylinders. I replaced the resistor with my old one and everything was fine again. I measured the resistance with a digital ohmeter and found that my old one had about 1.7 ohms while the new replacement had only about 0.6 ohms. On the ceramic is stamped 0.2 ohms.
Why would the replacement resistor cause the ignition problems?
