I called napa and they said the primary resistance on the 6 volt round coil is 1.26 to 1.4(I guess SB means made in CHINA). Isnt this too little to bypass the ballast resistor? Can I run 12 volt round coil on a 6 volt system with ballast resistor bypassed or are all too high in primary resistance?

keep oin mind thatt he front mount square can coils NEED the oe ballast resistor on 6v.

later N with 6v round coils DO NOT need a resistor to run on 6v.

what exactly are you trying to do.

a napa ic8 is a 6v round coil for a later sidemount N.. it needs no resistor to run 6v. an ic14sb is a 12v round sidemount.. it needs no resistor to run on 12v.

Quoting Removed, click Modern View to seeThat will be is within reasonable range.
If a "true" 12v coil with no ballast req'd, then it will be >3 Ohms & if you use it on 6v, the current will be too low & no run or weak spark & perhaps cut out at high speed & poor if any cold start.
