Alternator Troubleshooting Trick

[joseph20]

Mga experts, totoo po ba yung tricks o troubleshooter technique sa alternator na Once na tinnangal yung negative clamp habang umaandar yung auto and then namatay, my sira o may diperensya yung alternator?? Effective po ba iyon. TnX im aDvance

[yebo]

if you mean removing the negative battery clamp when the engine is running, then the answer is yes. the alternator should be the one providing the electrical power needs of the vehicle when the engine is running and not the battery, so disconnecting the battery with the engine running is a means to test the alternator.

That's a nice trick! I'll try that nga

Sir, kung both negative and positive tinanggal ko, then hindi naman namatay, meaning ayos pa alternator ko?? Subok na po ba talaga ganitong technique?? pagnamatay makina, sure means nun na may sira alternator ko po?? tama po ba?? TnX sir

[technismo]

sir kahit buong battery p aandar pa din yan.. hehehe may function check yan para malaman kung malakas pa yung alternator mo po... tnx

I've heard some trick of placing the screw driver's tip at the center of the alternator and if it get magnetized then they say that it is functioning . . . not sure though if that is true but induction might really generate some electromagnet.

pwede lang yan sa old school systems

sa mga modern vehicle systems marami nang modules na pwedeng maapektuhan pag nag spike ang alternator ( maaring masira ang module)


pag diy kailangan nyo volt meter

* idle ( without load)= around 13v- 14.8 v okey yan

full load ( head lights ,A/C defoggers , radio ON ) at least 13v * idle ,ok

^ true, the screwdriver must be placed in the positive output of the alternator. IMO removing negative battery pole is risky way of checking alternator and not adviseable on engines with onboard computer. Sa mga diesel engines at carb ok lang to. The most accurate way of checking is to use Voltmeter-reading must be above 13.5VDC (loaded or unloaded) and should not have AC component.

TnX mr Bambino. Sir, kasi pinacharge ko lang battery ko for 2hrs. Kung yung readings ng volt meter is nasa around 13.5 to 14, ok paba battery ko? hindi ko pa kailangan palitan??

Yup, the alternator with its rotor, stator and brushes is practically an electromagnet whose output voltage is regulated by the IC voltage regulator or in some old models, diodes or rectifier assembly....
