Your charging system is not working. Check your ALT-S fuse.
Your carbon brushes might be worn out

[QUOTE=dr. d;2890582]have your alternator seen by an alternator specialist, po. (yock's comes to mind.) they'll also check your system, to make sure that it is indeed, the alternator...
sometimes, all that is needed is to replace the electronic module inside. it's still cheaper than purchasing a used or new alternator.
and, done properly, it'll last many more years.

of course, purchasing a brand new alternator is an easy fix.

the assumption is, you do not have any power-hungry appliances in that car.[/QUOTE

alternators are built to last.
so, bakit nasunog?
kasi, baka masunog din yung kapalit?

You def don’t need a high powered alt unless you running 1000’s of watts...
first check if your alt is working correctly..
car switched off should be 12.4v , car switched on should be 14.4v
Next get a bigger battery and do a big 3. Search google for ‘big 3’ if you not fimiliar with this term.
If still you having electrical issues, then check your relay, that might be damaged and draining current

Yes you can, just make sure to add an isolator or split charging diode kit to prevent your system from depleting the starter battery once your "leisure" battery is exhausted. You can buy the kit on car audio accessories shop.
