Alternator!

Hi medyo noob sa cars, ask ko lang sana if may nakakaalam ng price range ng alternator for a 2010 ford escape medyo nagffluctuate kasi battery voltage ng bigtime if may electronics na gunamit. Maayos naman ang wirings and cables. Alternator kaya ang problem and how much kaya? Salamat sa replies!

hindi kaya maluwag lang ung mga battery terminals mo.or di kaya kulang sa ground.
pa check mo sa battery station may pang tester sila dun at malalaman kung battery or alternator ang problema

yup napachek na namin, nadrain din battery namin despite hindi naman ginamit or wala naman naiwan electronics na naka on.

take note twice na drain, pinacharge namin nung una pero the next day naubos din laman ng battery

baka naman battery ang sira, kasi kung alternator yan dapat itinirik ka na ng car mo, but since nag start pa din car mo, nagbibigay pa din ng charge ang alternator, ilan taon na ba battery mo?

check mo din ung size ng battery mo, kung maluwag sa battery holder undersize ang battery mo kaya nakaka experience ka ng kinakapos pag on ang electronics mo.

It is not difficult to have the alternator checked. It is usually done for free by decent battery outlets.
Alternators are pretty robust items, and can outlast the engine. Typical problems include:
Brushes. These are wear and tear items, and are easily and cheaply replaced.
Electronics (ICs, diodes). Also easy to replace, but much more expensive than brushes.
Winding burnout. Uncommon, but possible.
Once the alternator is shown to be the culprit, it can usually be fixed by a good alternator repair shop.
Fix versus replace... If brand new, fine! Just be aware that new units are expensive.
Surplus? I prefer to have mine repaired.

If the cause of the problem is battery, then you should have no signs at all when the engine is running. With the engine running, the electricity needed is provided by the alternator, not the battery.

Unless... Your electronics require more power than the alternator can provide. In which case, your battery runs down.
What is your electronics requirements?
