Voltage question

[ParticleX]

Ask ko lang if within normal pa? Terrano JDM TD27 Turbo, Motolite Gold 3SM 2+yrs

(lahat on idle)
No accessories): 14.1v
With aircon, max setting: 13.9v
With aircon, headlights and signal lights: 13.1 - 13.2v
With aircon, headlights, signal lights, radio, dome light: 12.8 - 12.9
Off: 12.5 - 12.6v

Di ko macheck ang voltages kung nakaapak ang silinyador kasi wala akong kasama at malayo yung cable. Sa gabi very slightly humihina headlights pero pag apak ok naman uli.

Thanks papalagay sana ako ng 2 aux fan sa condenser, di kaya masyado nang bababa pag simultaneous lahat sa gabi?

iadd-up mo lahat ang power ratings ng lahat ng electrical consumer ng sasakyan mo. refer ka na lang sa google sites how to estimate such things.

quick formula is the ohm's law: P = IV where, P-watts, I- amperes, V-voltage.

then check mo rating ng alternator....for longer life ng alternator 60-80% percent or even lower ang loading nya parati. huwag mo i-100%.

relatively malakas din lumamon ang electric fans kaya better do the math first before doing modifications.

volatge reading looks normal to me.
