> > I fitted a high energy coil to my 405 a few years ago, with beneficial results - never any problem with misfiring. However, this type of coil may need to have a ballast resistor fitted, which reduces voltage to the coil of about 7 volts, lessening wear of contact points, etc.. But this may require the fitting of a modified starter solenoid to allow the ballast resistor to be by-passed to ensure full battery voltage to the coil during starter motor operation. This momentary voltage overload is acceptable, but continued operation without the protection of the ballast resistor is likely to lead to damage to the coil.
