Re: Karizma/Karizma R
In old times In Ignition coils,,Inter winding insulation, insulation between primary and secondary winding ,used to be thin paper and entire winding dipped in transformer oil for insulation .. so they used to be large and would still heat up under load....Present day we use Hi Temp Polymers and Epoxies to form permanent Insulation which also resists moisture ingress, which was a main reason of problem before...The Insulation on the copper wire used for the winding is also now improved....Still increasing secondary Ignition Voltage beyond a certain level will cause Arcing and failure....so for every engine like other components, the Ignition coil and it's drive circuit are pre-selected depending on the engine's operating parameters....Having more than one resister in the circuit will definitely reduce the spark current .
