[QUOTE="azam318, post: 386472, member: 5974"] Hi All Sifus, thanks for giving the great ideas and advices. Just now, I did some checking on the battery connections. And I've found out the negative connector with improper tighten(dry joint) which is not tight enough. So, I re-tighten the -ve connector and now my engine can be start with no problem, seem like its become a normal engine. So, I decided to do the voltage measurement using the Digital MM as shown as below. [B][U]Findings;[/U][/B] While engine not start, the voltage shows as 12.63VDC. Then after start the engine without any loading the reading shows as 13.50VDC not even reach at 14VDC. The reading will drop as 13.10VDC after all the electronic parts on 'ON' stage such as switch on all the lights and air-cond, all the doors and boot open, all the interior lights is on. After done the measurement, can I conclude that, my alternator is not in good condition which is need to be change? If yes, how much does it cost me? Is it ok if I get the part from the chop shop or the recond one? If NO, is it the faulty because of the -ve connector loosen? Pls advice.
