CHECKING OF THE ALTERNATOR STATOR
After visual checking of the coils which must not show heating or oxidation traces,check
the resistance and the insulation of the coils.
A.CHECKING OF THE COILS INSULATION
After placing the ohmmeter terminals on chassis ground , on “ I point and on one of the
three terminals marked with “ f “ , “ g “ , “ h “ , the ohmmeter needle must not deviate
( resistance = ).
B. CHECKING OF THE COIL RESISTANCE
Place in sequence ,the terminals on the coils extremities: “ f “ and “ g “ ; “ g “ and “ h “;
“ f “ and “ h “, the values of the measured resistances must be equal in the three cases , the
maximum allowed variation being of + / - 5 %.
