PROCEDURE
| 1. | CHECK HARNESS AND CONNECTOR (STEREO COMPONENT EQUALIZER ASSEMBLY - STEREO COMPONENT AMPLIFIER ASSEMBLY) |
(a) Disconnect the G15 stereo component equalizer assembly connector.
(b) Disconnect the G12 stereo component amplifier assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| G15-12 (CH1+) - G12-8 (AN1+) | Always | Below 1 Ω |
| G15-26 (CH1-) - G12-16 (AN1-) | Always | Below 1 Ω |
| G15-11 (CH2+) - G12-7 (AN2+) | Always | Below 1 Ω |
| G15-25 (CH2-) - G12-15 (AN2-) | Always | Below 1 Ω |
| G15-10 (CH3+) - G12-6 (AN3+) | Always | Below 1 Ω |
| G15-24 (CH3-) - G12-14 (AN3-) | Always | Below 1 Ω |
| G15-17 (ACNT) - G12-3 (ACNT) | Always | Below 1 Ω |
| G15-12 (CH1+) or G12-8 (AN1+) - Body ground | Always | 10 kΩ or higher |
| G15-26 (CH1-) or G12-16 (AN1-) - Body ground | Always | 10 kΩ or higher |
| G15-11 (CH2+) or G12-7 (AN2+) - Body ground | Always | 10 kΩ or higher |
| G15-25 (CH2-) or G12-15 (AN2-) - Body ground | Always | 10 kΩ or higher |
| G15-10 (CH3+) or G12-6 (AN3+) - Body ground | Always | 10 kΩ or higher |
| G15-24 (CH3-) or G12-14 (AN3-) - Body ground | Always | 10 kΩ or higher |
| G15-17 (ACNT) or G12-3 (ACNT) - Body ground | Always | 10 kΩ or higher |
| G12-13 (ASG1) - Body ground | Always | 10 kΩ or higher |
