Battery Warning Light

**step22** · October 5th, 2014 11:37 AM

What could be the problem nakailaw yung battery warning light sa dashboard ko, but only slight hindi tulad nung pagbinuhay mo susi yung umiilaw lahat hindi ganung katinkad parang slight red lang. hindi siya nawawala. sa alternator pa rin kaya? kasi nagchacharge naman siya. gumagana naman lahat ng electrical components ko. malakas din batt. ano po kaya yun?

Voltage Readings meron ka? kung higher than 12.6 (say 13.3 Volts) pero hindi lalampas ng 14.3 volts e ok ang charging system mo. otherwise, faults sa mga components

usually pag umiilaw, check mo yung battery terminal, baka maluwag lang, or baka puno na nang puting bagay na parang powder.. linisin mo lang, or, kung undercharge, baka alternator... kung hinde naman sira, baka maluwag yung belt .. also try the first answer. voltage reading.

corrosion is also a major contributing factor on charging system problems as well as connection. isa akong biktima neto...akala ko may dwende na naman wirings ko. yun pala maluwag ang terminal. i say much better ang copper clamps than the lead clamps. mas prone to corrosion and loosening ang lead clamps than the copper clamps.

take a voltage reading sa cable just before the battery clamp and a voltage reading at the battery terminal. greater than 0.5 volt difference is considered to be high. yung sakin nga last time more than 1.5 volts ang difference.

wala po akong pang voltage reading. pero i cleaned both poste at terminal ganun pa din. then i tried na pag palitin battery ng other car namin ganun pa din umiilaw pa rin. i know its a warning light but nothings wrong naman. maybe the warning light is wrong hehe? or di kaya grounded lang sa ibang lights sa dashboard? kasi slightly on lang yung warning light or sadyang ganun lang?
thanks sa mga above poster na nagreply.

anong sasakyan, po?

do you have weak battery symptoms?
if you do, consider the ff:
1. alternator problem
2. electrical connection problem.
3. slipping alternator belt problem... ayaw magkarga nang mahusay. try tightening it po..

puede siguro nyong pa-check sa disenteng battery store. libre kong napapa-gawa ito. madali lang gawin... kina-clamp lang nila yung checker nila sa battery..
