Probl\u00e9my s nab\u00edjec\u00edm syst\u00e9mem<\/h3>

Baterie nen\u00ed jen pasivn\u00edm zdrojem energie - je sou\u010d\u00e1st\u00ed syst\u00e9mu. Altern\u00e1tor mus\u00ed dod\u00e1vat alespo\u0148 13,8 V, aby ji udr\u017eel nabitou. Kdy\u017e se tento proud sn\u00ed\u017e\u00ed, baterie se vybije. Tich\u00fdm sabot\u00e9rem je \u010dasto nefunk\u010dn\u00ed altern\u00e1tor nebo uvoln\u011bn\u00fd hadicov\u00fd \u0159emen.<\/p>

L\u00e9pe udr\u017euj\u00ed nap\u011bt\u00ed p\u0159i z\u00e1t\u011b\u017ei, tak\u017ee se na pap\u00ed\u0159e zdaj\u00ed b\u00fdt \"zdrav\u011bj\u0161\u00ed\".

Zde je pozn\u00e1mka na okraj: P\u0159edstavte si baterie jako lidi, kte\u0159\u00ed b\u011bhaj\u00ed maratony.

Jak zkontrolovat nap\u011bt\u00ed autobaterie<\/h2>

Pot\u0159ebn\u00e9 n\u00e1stroje<\/h3>
  • Digit\u00e1ln\u00ed multimetr (na Amazonu ho se\u017eenete za m\u00e9n\u011b ne\u017e $20)<\/li>\n\n
  • Ochrann\u00e9 rukavice (doporu\u010den\u00e9, ale j\u00e1 se bez nich obe\u0161el)<\/li><\/ul>

    Pokyny krok za krokem<\/h3>
    1. Vypn\u011bte motor a nechte v\u016fz alespo\u0148 1 hodinu st\u00e1t. Tato doba odpo\u010dinku je kl\u00ed\u010dov\u00e1; testov\u00e1n\u00ed ihned po j\u00edzd\u011b poskytuje zkreslen\u00e9 v\u00fdsledky.<\/li>\n\n
    2. Nastavte multimetr na stejnosm\u011brn\u00e9 nap\u011bt\u00ed, obvykle v rozsahu 20 V.<\/li>\n\n
    3. \u010cervenou sondu p\u0159ipojte ke kladn\u00e9mu p\u00f3lu baterie (+) a \u010dernou sondu k z\u00e1porn\u00e9mu (-).<\/li>\n\n
    4. P\u0159e\u010dt\u011bte si nap\u011bt\u00ed. Porovnejte ho s v\u00fd\u0161e uvedenou tabulkou.<\/li><\/ol>

      Kr\u00e1tk\u00e1 rada z vlastn\u00ed zku\u0161enosti: Pokud nap\u011bt\u00ed p\u0159i startov\u00e1n\u00ed klesne pod 10 V, je baterie pravd\u011bpodobn\u011b p\u0159ed poruchou.

      Jak prov\u00e9st z\u00e1t\u011b\u017eov\u00fd test<\/h3>
