Note

To check the battery charging system for faults, use the dds diagnosis instrument and follow the instructions given in the paragraph, "testing the battery charging system" (sect. 6 - 11).

The absolute value of voltage measured across the terminals of two of the three yellow cables (the measured value will be the same whichever combination of cable is used) must be within the range indicated in the table below.

(Ambient temperature: 35 C - 70 C)

Important

Before testing, disconnect the alternator wiring from the electrical system when the ignition key is set to off.
