Powerdynamo brings new ignition & light
|There are conditions under which it might be desirable to drive without a motorcycle battery. Most Powerdynamo systems are well capable of running without battery. But there are certain facts to know and observe.|
|What has to be observed when driving without battery?|
|parking light||No battery = no light whatsoever when the engine is at a
standstill. This is something you should not ignore!
Note: A possible installed condenser has no storage capacity and will not provide light for any amount of time.
|legal aspects||Please consult your local regulations whether you are permitted to drive without parking lights, This might vary from country to country. The regulations for Germany are given here (in German).|
|possible technical problems|
|blowing of light bulbs||We have had customer reports that in uses without battery
and without condenser, light bulbs tended to blow when light was switched
on. Indeed, without any load (neither battery loading, nor light) idle
voltage may climb to 17 volts and return to normal only after light is
switched on, and a load induced.
Knowing that it does work well in most instances, but confronted with individual customer complaints who had bulbs blown, we do expressly state that you will have to install a condenser, if the battery is not used.
|horn does not sound clear||As a result of the pulsing current the horn will not sound clear, but more like croaking. It will still be loud though.|
|side indicators||Not all flasher units will work properly without a battery. Most will go haywire. A strong capacitor will help to solve the problem.|
|electronic rev counter||Electronic rev counters need normally a stable DC voltage. Without a battery they will not function correctly function. (Electronic rev counters on Powerdynamo systems are a matter of special consideration).|
|relay option not possible||Powerdynamo systems which replace dynamos have a relay for
shut off. Without battery the relay will not function. You will have to
facilitate the engine cut off by means of a kill switch that connects the
blue wire of the ignition coil (or black box) to ground.
Bikes which had been equipped with magnetos will already have such a switch installed.
|only 10 Volts on instrument?||Many customers want to check the voltage coming out of the new regulator (understandably, as the old system tended to be to low). When the multimeter hooked up, you will notice that it will read only 10 volts or possibly less. Although the headlights are shining to their fullest capacity. What is happening is that the meter gets fooled by the absence of a battery (or a condenser) by the pulsing DC voltage. Both are actually ok, system and meter, but the reading is wrong. So don't worry. If one does not believe this, you may test it with or without a condenser installed.|
|At idling speed the system will not have its full output. It might be that as a result (notably with 6 volts inner sensor systems) show a dimmer light at idling. That will rapidly brighten up however at higher revs.|
|Some older Powerdynamo Systems for 4 strokes (Type 899) need a battery for the advance unit.|
