Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords.

Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production toler- ances.

Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal production toler- ances.

Circled numbers refer to waveforms.
