Alternator Troubleshooting Trick

[bambino]

kung 13 to 14 pa po yung reading ng voltmeter, meaning po ba nun na ok pa yung battery at alternator ko po??

to find out if the battery is good:

cranking test
ign coil HT wire grounded

votlmeter hooked up

crank continuously for 30 seconds

while cranking , batt reading should be at least 9.6 V

less than 9.6V = no good
