baka may maliit na wire sa tagiliran ng alternator mo. kung minsan kasi ay kumakalas o lumuluwag...

Baka mahina output ng alternator. If that goes on, mamamatay ang battery mo. Pa-check mo sa Auto Electrician.

You have to check which side of the circuit has the high resistance. The way you described it, the problem is more than likely the chassis ground since you have problems with the other loads as well.
Get a DMM (digital multimeter) . With a fused jumper, check the voltage between the battery terminal positive and the negative terminal of the headlight socket. Do this too between the battery negative and the positive terminal of the headlight socket. The voltages should not be less than 0.5vdc less than the battery voltage. If one side displays a low voltage, that side has the high resistance.

bro, nangyari din sakin ito mga ilang buwan na, assuming all stock pa electrical system mo, ipa check mo yung external voltage regulator or alternator.

How many years your motor has?

ano pong motor ung sinasabi nyo?

update lang regarding dito.....I ended up buying new battery, kasi isang araw it went dead...pero when I got a new battery still the same guages and light. Mahina sya talaga....ok lang ba na taasan ko ng wattage ung mga peanut bulbs sa dashboard? Headlight sinasabi ng electrician is palitan ko na daw ung assembly kasi foggy na ung plastic...kaya malabo na.
