IINM, i read before in GAGA thread, somebody tell that our gaga alternator not give sufficient charge to battery
i buy something that wrote "Battery Check" tools
plug into ciggarate lighter port, to doing battery check
when i do test to my FLX, the result:
battery check (when engine off) = battery in good condition = green
alternator check (when engine idle/drive) = not enough charging power = yellow+green
can i trust this tools?
or it's real our gaga alternator not have enough power?

Hi Bro...
Juz use that device as a rough guide. As long as in a green zone, it's ok.
Best for home chk is 2use a branded Multimeter set to Voltage mode. W
IINM 13.9V to 14+ V reading shows good alernator functioning...depending on time/rpm of engine.
Idling @start of car shld b 14+V.
ps. Me rber Bro YAB David did a detailled post on car voltage chks/readings recently. Pls do a search.
