the paghina ng panel gauge, HU and mga ilaws, are signs of very weak battery.

three common causes of very weak battery, include:
1. battery is discharged because either someone forgot to turn off something overnight, or there is a defect causing big drain. identifying and correcting the cause of the drain, will relieve the issue.
2. battery is old or defective. replacement is the only option.
3. alternator is defective, causing battery to go flat. usually, fixing the alternator problem will revive the battery.

good luck.

speaking of...
many years ago, my 1976 toyota corona RT100 's battery ran flat.
the culprit was a one foot length of thin electric wire near the alternator, whose one end was hanging free. i simply looked the socket it came from, and pushed it back in.
buti na lang it was an MT, and was able to push-start it. the battery was good and strong after an hour of fast driving.

When does that happen?

1. During starting?
2. While the vehicle is idling/running?

Mas madali ang panghuhula by "elimination method" kung gagamit ka ng plug-in cig-lighter Voltmeter na mabibili mo nagkalat online.

13.5-14.2V charging Voltage

11.8-12.5V engine off voltage
