electronic revolution counter (Tachometer)

	electronic revolution counter (Tachometer)
Note	The issue of electronic tachometers (revolution counters) is unfortunately much more complicated than you might think. There are countless versions and plenty of differing technical situations the unit might work in. Many customers think they just need to know where to connect the tachometer and all is settled - well it definitely is not.
	We are glad to (again) present a solution to connect electronic Tachometers to Powerdynamo generators on the basis of Instruments from MMB. This solution consists (as it did years back) of a small module housed in a relay box which brings the frequency signal from our alternators to a signal the MMB Tacho can correctly reed. The module gets connected via some distributer cable (arriving with the module) between alternator and ignition coil (or advance unit, depending on model).
	You need an MMB instrument which can read a positive pulse in a ratio 1:1. This is true for the presently offered EEDM instruments from MMB. This ratio is independent of how many sparks your Powerdynamo system delivers per revolution as it does not take the pulse from ignition, but from the alternator You may choose housing, dial and illumination when buying online with MMB. our tacho module (adapter) battery 12V in the system to drive the tacho needle. If you want to drive without battery you need a smooting condenser or our alternative regulator with inbuilt condenser MMB offer a 6 to 12 converter for instruments running in 6V environments

	Stock revolution counters possibly existing on various motorcycles can normally NOT be driven with signals from our systems. It may be that they function, it may be that they do not or wrongly so. We can not tell and we do not know and therefore we can not offer any support on those materials. Same is true for aftermarket Tachometers other than MMB. As there are so many makes and versions, we have not tested the solution in combination with instruments of other makes. We know however for sure that - very unfortunately - it does not work with the Pitsch LZ13. If however your stock points had not been sitting on the (now gone) dynamo/alternator, but the camshaft or as in some cases the other side tof the crank, you may keep them to drive the Krober (see tip below).
	If your stock Tachometer has been driven by points (contact breakers) which will not get eliminated by installing Powerdynamo (as they sit either on the camshaft or the other side of the crank) you may keep the points to drive your Tacho and all is fine again.
