For our third week in Electrical we did charging system testing

  • The 1st thing we did was a visual inspection. Checking for leakage, corossion around termainals, loose connections and any other damage to the battery. The Wiring was checked for losse connections, cracks, splits, and any other damage. The Alternator was inspected for any physical damage to it and poor connections from the wiring.
    During our Visual inspection we noted down some corossion around the battery termainals and some acid sitting on top of the battery (leakage)
  • Then we tested the condition of the battery. With the Multimeter we did a OCV test which we got 12.6V. Then a hydrometer test checking the Electrolite levels in each cell of the battery which we got 12.10 for each cell except the last cell where our result was 12.50
  • After that we checked the condidion of the drive belt. Rotating the engine by hand and checking for signs of uneven wear, cracks, splits and any other damage to the belt which would cause failare
  • After that we tested the Alternator with no Load on the car. Using a Voltage meter we had the engine running and connected to the + of the Alternator and - off the battery. We made the engine run at 2000 rpm and recorded our Voltage result.
  • This time we did the same, testing the output of the Alternator but with load on the engine. So with it running we stiched on interior and exterior lights aswell as the stero and heater. Anything to draw power from the battery.
