In process of doing a full tuneup and I noticed the new coil I bought (NAPA part # ECH IC7) is marked "Use with external resistor". There was none on the old coil. Not sure if I need to add a resistor??? My electrical "knowledge" is some where between caveman and 2nd grader  so any help/advice would be welcome. THANKS!! | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy 54hydramaticFL, six volt coils do not need external resistors, are you sure the coil is a six volt coil? Perhaps they put the notation on the coil in error, hope that helps. | | |
