Cagiva Mito 125 Charging , generator , alternator , stator and pick up coil testing

Alternator output tests 









Start the engine and run to 6000 revs per mintue as this is the speed at which the alternator starts working .

The attach voltmeter at to volts and test at the battery terminals reading should be 13,5-15v

if its less than this you have charging circuit problem if more than this a possible reg/rectifier problem .

Need a Multimeter try here mines a kewtech and it has been excellent .




Alternator coils testing 





Set multimeter to ohms , test measurements between 2 yellow wires and then  yellow wires to earth .







                                  Testing between yellow wires im getting 0.4 ohms my bike is running 
                                            so id say between 0.5 - 0.7 should be ok readings .





Test between Yellow wires to earth or body of stator ,  to ensure you 
have no shorts direct to earth 

                                             


Need a new Alternator Stator ?  try here



Pick up coil testing 




Pick up coil is important as a rank position sensor  spark pv timing .


here is how i test mine and mine was fully working so measurements should be ok



test between red/black wires now 


im getting readings of around 100 omhs on a working pick up coil
