Powerdynamo brings new ignition & light 
to your vintage motorcycle



Technical Help



Some customers have problems in starting magneto based Powerdynamo systems as kickstarter revolutions are too low to reliably start the system. To help this, many systems may be converted to a battery based system start already from about 150 revs/min onwards, rather than the 320 needed by magneto systems. 

The modifications needed differ depending on whether the system has internal or external pickup.
Unfortunately not possible is to modify internal trigger systems with advance unit.

In all cases a converter is used to convert battery voltage 6 or 12V to the needed condenser charge of about 360 volts. There are various types of converter, depending on use. Please do not confuse the converter with the advance unit, even though they have the same housing - they are totally different parts.

A different ignition coil (coil 7025) is used. this coil has 2 input lines, one for the magneto and one for the converter.
This coil is available as twin or single coiln coil.

making internal sensor systems  with advance units battery powered is NOT possible!
