Det er kun teknikere som har fullført alle nødvendige sertifiseringskurs som har tillatelse til å utføre denne prosedyren. Tesla anbefaler at teknikere fra eksterne serviceleverandører gjennomgår tilsvarende opplæring før de utfører denne prosedyren. Se sertifiseringskrav for høyspenning for mer informasjon om Teslas krav til teknikere eller beskrivelser av emnet for tredjeparter. Egnet personlig verneutstyr (PVU) og isolerende høyspenningshansker med minimumsklassifisering 0 (1000V) skal brukes til enhver tid ved håndtering av høyspenningskabler, samleskinner eller fittinger.

  3. Disconnect 12V/LV power. See 12 V-/lavspenningsstrøm (koble fra og koble til).
  4. Set the current clamp to measure voltage , and then measure the voltage across the 12V/LV auxiliary battery terminals using the test probes.
    Informational PurposesAn informational icon, calling your attention
    Merk
    For LV (Li-Ion) auxiliary battery: if the voltage across the battery terminals is 0, the battery may have switched off internally. Use a 12V Lead Acid battery for testing. For mobile technicians: use the 12V Lead Acid battery in the Mobile Service vehicle.
