per my auto experience, as long as hindi na discharge ang battery and the system voltage hovers 13.4 volts.. its good..
if voltage while idling is =<13V.. yan, may problem na ang system, either loose connection or the alternator is getting weak..
yung 14volts is usually the alternator's output if the battery is severely discharged where it barely started the car..
usually when you use accessories like radio for extended period with the engine off.
share ko lang din experience ko with alternators.. may diesel van kami dati na every time we use it, after 1 hour of driving eh na discharge yung battery.. kaya pag dating ng tatay ko sa office nila, he will charge it using a 220v charger.. then go home again with the battery discharged..
every time na dadalhin namin sa auto electrical shop, pag check nila, ok naman ang alternator charge.. 13.5V or higher pa nga.. medyo matagal tagal din na ganun yun.. pinalitan ko na fuse, wires, battery terminal.. ganun pa din..
until napag tripan ko buksan yung alternator.. upon closer inspection ko sa magnifying lens, ayun may mga crack pala yung solder ng diodes.. although may voltage, since loose yung diodes, nag intermittent on/off sya na hindi namin mahuli sa tester..
dinala ko dun sa isang electrical shop na may heavy duty soldering gun.. problem solved!
