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
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
