Coil w/ballast resistor vs internal ballast
'73 CORONA 18RC
I was looking into a coil w/o external ballast. I did some research but mostly got info from Rockauto searching and tech people @ NGK. Heres what I found and wanted to run it through here to see if anyone had these experiences.
My application calls for NGK coil #48774 w/ external ballast(external ballast is required so that it reduces the 12V down to 8-9V so it doesn't burn up the points (is this continuous or only when it is started up!..IDK, could find that info). So, here say, says better performance is obtained w/internal ballast, so I found (through NGK techs) NGK coil #48863 has a internal ballast. I'm having a little problem of backfiring while cruising and let up off the gas(no exhaust leak, but it also may be due to valves not closing,timing chain in need of changing)...so taking this one little step at a time.
