Triumph TR6 Ignition Leads Coils and Spark Plugs
The 6 volt (ballasted) coil system was introduced on CR/CF models to assist with cold starting in seriously cold winter spells and climates (as the amperage from the coil is doubled). For an even more generous spark the 6 volt sports coil can be substituted here.
For those who wish to eliminate the ballasted system and return to a 12 volt coil system, the ballast resistor can be bypassed by running a suitable grade wire from the fuse box straight to the coil, having removed the existing coil feed ( from the ballast resistor). Fuse box outlet terminal number one should be used as on earlier applications.
