| STEP | CHECK TO BE PERFORMED | REMEDIAL ACTION IF THE CHECK IS NOT OK |
|---|
| 1 | Check the wiring- Check that the connector is correctly inserted in the other part.
- Try to move it from its housing by making small movements in all directions, grasping the connector body in your fingers and the wiring in your hand. The connector must stay in place
- Exercise a moderate pulling force. The connector must stay in place
- check whether the power supply goes off, goes on and/or vice versa (touching/not touching)
- Pull the lead and check the stability in the groove (should not move back): exercise repeated pull-push-pull cycles on the cable and check it remains immobile.
Examine the crimping:Use a lens to examine the terminal crimping area. The barrels must be turned symmetrically and no strands should emerge from the crimped area. The bare wire section under the barrels must emerge by 0.5 | Restore the correct positioning of the connectors |
| 2 | Check power supply (+30)Check for battery voltage +30 between pin 4 of the radio connector A and earth | Check the continuity of the +30 connection between the Body Computer (fuse F36) and the radio See E3510 RADIO |
| 4 | Earth checkDisconnect the negative battery terminalDisconnect amplifier connector A and connect an ohmmeter accross pin 8 and earth and check the resistance is lower than 1 ohm | Restore the earth connection on the chassis in the area of the left dashboard |
| 5 | Amplifier enablement power supply checkTurn the key to the ON positionUsing the voltmeter, check for a battery voltage between pin 5 of the radio connector A and earth | Restore correct power supply See E3510 RADIO |
