Finally some sounds in the car
This has been going on for some time now, but I’ve wanted to replace my factory head unit with a better one. The standard one in the Nissan isn’t exactly the best, it does the job but the CD player part was broken and it was annoying me.
I didn’t want to chop any of the wires incase I decided to sell the car at a later date, so I purchased an ISO harness.
As an FYI, the Nissan Almera doesn’t have an earth connection through the factory wiring harness. The earth connection is done to the chassis of the vehicle through the earth wire and the metal cage that holds the head unit in
Now, I fitted the head unit to the vehicle, wouldn’t power up. Balls. Went over it again, now worked. Great. I had to order an DIN–>ISO aerial adatper because the factory one didn’t fit my Alpine head unit. The standard aerial is one of those thick ones, and the normal adapter you get is usually the reverse (thin > thick), so I purchased a replacement
I went to it the next day, no power again…. annoying.
I pulled it out the day after, multimeter at the ready and tested the earth and +12 power wires. All working, test the head unit fuse, that works, ok, must be the head unit. No power… shit. Did head -unit
I unplugged the power wire and plugged in again, now working. What the hell. Sod it, it’s working for now. That will do
I’ll look into it further when I get the replacement aerial wire to see if I can figure out what’s wrong. It’s using a harness wire and there’s a connector which goes from factory harness (albeit it’s a bit loose) to the alpine ISO
I’ll post more if I figure it outViews – 250
