Tolerant Troubleshooting Procedures is as Primary as Having the Hold up Tools
Undesirable bellow, a destitution of sound, and amplifiers stuck in Safeguard resources are all matters that hinder Pleasure of machine audio systems. Although age consuming and sometimes frustrating, learning some basic troubleshooting techniques is a advantageous Appendix to the factor box, exactly attached to the crimpers and t-taps. Arrange that they are place to minimum.6. Repeat Method 4, listening for tumult.7.
1. Turn on vehicle's engine.
2. Turn on Disc as source from radio (sense unit).
3. After pausing Disc, turn manual 3/4 unabridged.
4. Urgent Gauze pedal lightly, listen for increases in whine and/or "ticking", etc.
5. Access amplifier. Trial gains. Gimmick on investing appreciable duration to not individual come upon the difficulty, nevertheless bewitching the day to establish it doesn't happen again. Checking and securing all course connections Testament disclose uproar sources, and cinch installation safety.
Instructions
Noise and Connection Integrity
Heading back to amplifier, slowly exaggeration buildup in incremental steps, pausing to repeating Process Four after Everyone slender copper. Flash on that gains place further grand Testament amplify air and clatter in Identical degree.
8. Whether resetting advance constitution does not solve the complication, allot grounding mark of development (amplifier). Clinch existence is tightly secured and corrosion/rust chargeless.
9. Provided grounding mark has contamination, tun off vehicle and access vehicle battery.
10. Using socket set and appropriate insert, remove negative lead from vehicle's battery. Use electrical tape to secure this lead.
11. If noise disappears after disconnecting RCA leads from radio, head unit (radio) may be the cause. Proceed to Step 19.19. Locate small screw on radio's chassis. Remove using small screwdriver (probably Philips).
13. Using appropriate tool, re-secure ground. This is a good time to ensure all system components are grounded to the same location. Failure to do this may result in a ground loop, causing noise.
14. After grounding location is cleaned and all connections are secured, remove electrical tape from negative battery lead and, using socket wrench, re-attach to battery. Turn vehicle engine back on.
15. If noise is still present, access rear of head unit (radio) using appropriate radio keys/socket wrench/screwdrivers.
16. Remove RCA signal leads from radio (head unit). Insulate ends using electrical tape. Repeat Step 4, listening for noise.
17.If noise is still present, noise is generated from amplifier. Ensure all RCA/power ground leads are secure. If noise persists, consider removal of the unit for service.
18. Using appropriate tool, remove existing ground connection. Insulate this lead using electrical tape.12. Using Dremel tool (or other scraping device), remove any rust or corrosion present. Installers should only see shiny, bare metal.
20. Using crimp tool, attach Sixteen gauge ring terminal to radio's black ground wire.
21. Using small screwdriver, attach this ground wire to the screw removed in Step 19. End result is radio's ground is secured to radio's chassis.
22. If all steps are now complete and noise persists, issue may reside in radio (head unit). Consider removal for service.
Non-Functioning Equipment/No Sound
23. Access vehicle's battery. Using appropriate socket insert, remove negative battery lead. Insulate using electrical tape.
24. Use appropriate radio keys/socket/screwdrivers to access rear of radio (head unit).
25. Locate white cylindrical fuse holder for radio (head unit). Unscrew and check fuse. If metal piece in fuse is broken, remove and replace with same value. Keep radio out of dash for future steps.
26
If sound hasn't returned, locate system fuse (should be located within 18" of vehicle's battery). Remove and check. If brown "smoky" material is visible, it is probably blown. Remove and replace.
27
Using appropriate socket insert, re-attach negative lead to vehicle's battery.
28
With radio still removed from Step Three (Section 2), locate blue remote turn-on wire. If external amplifier is present, this should be coming from head unit's harness.
29
If radio turns on, but external amplifier (if present) does not, turn off radio.
30
Using wire cutters, snip remote lead from head unit's remote turn-on lead.
31
Using vehicle's electrical schematic, locate "ACC" wire. This is the wire that energizes small electrical accessories when the vehicle is turned on.
32
Using wire crimp tool, connect remote turn-on wire and "ACC" wire, located from Step Nine (Section 2) with Sixteen gauge plastic T-tap connector.
33
Re-start vehicles engine and check for sound. Consider professional assistance if nothing is heard.
