Will the factory BOSCH ignition system on a late 120 which uses motoplat 5 ohm ignition coils be able to use 3 ohm coils without damaging the ignition?
The current is gong to go from 2.4 amps to 4 amps due to the lower resistance. One of the coils is bad so am replacing them with TEK KP03 coils which are 3 ohm.
This is temporary as the BOSCH ignition will in the near future be replace by a modern one which does use 3 ohm coils. But I don't want to damage the existing ignition system! If 3 ohms is not OK then I guess my only option is to use a ballast resistor. I need to see if the bike will start and run as it is now!
Also, opinions on the current available ignitions out there. I have three bikes with IIS ignition and one with DMC so am familar with them but know nothing about the Sachse ignition? Does it offer any advantages over the DMC?
