Tried to localize the sound using steth mukhang sa alternator nga galing. Mukhang di pwede ibyahe to.
Just sharing, farthest I drove with a broken alternator(battery light lits up and alt not charging) was from Lucena City, Laguna upto Apalit, Pampanga. From the time it lit up, planed my route and palipas oras muna to ease traffic on road. Turned off all electricals. This is on a car with computer box pa and a 2sm battery only. I think pajero fm has no ecu and uses 3sm battery. 12mn umalis ako SPC, dumating ako bahay sa apalit 1:30am+

Fully Charged the battery overnight and the following day, from apalit to manila, dinala ko oto to have the alternator replaced bnew. Brought a spare battery as well just in case ma trapik sa edsa at malow batt battery and mamatay ECU/engine.
