Hi all,
I recently purchased an aftermarket CD/DVD/SatNav etc unit off ebay to install in my 2007 Navara. After adapting the original stereo harness for use with the new stereo, I found that there was no Earth wire on the existing plug. I figured that I could get around this by hooking into an existing Earth nearby. I found a suitable Earth below the stereo, coming from the rear of the air-conditioning control. I tested the stereo, all was well, so i decided to screw everything back in place and put the centre dash panel back.
After doing so and turning the key on, an odd noise came from behind the air-con unit. Hard to explain what it sounded like. Intermittent for a few seconds. I turned the key off and tried starting the car. I heard the same noise again for a shorter duration this time, and noticed a range of warning lights on the dash (4WD, Battery, Filter?, Door (strangely indicating the opposite door to the one I had open), etc).
The car tried to turn over very briefly then stopped. I tried again several times, each time the car sounded less and less likely to start. Note, all over functions are working - lights, stereo (damn stereo) etc. Also note, that I had successfully started and moved the car only half an hour prior, and did not have any lights or similar on to drain the battery in this time.
I unscrewed the stereo and disconnected the connection, but the same outcome occurred. I.e. numerous warning lights and no start. I figured if the additional load had interfered with the Earth then disconnecting the load should return the system to normal?
I've hooked the battery up to charge for now to see if any difference results, but I'm not feeling confident at all. Have I activated a battery monitoring system or something? Or could I have damaged the wiring harness through heating it for heat shrink/cutting to use the air con Earth?
I'm sorry about the post not being too brief but I felt it was important to provide a lot of info. Thank you so much if you have read this far, and thank you in advance for any advise you are able to provide!!
