Hi all,
I'm just totally stuck by this problem.No matter how I power my headunit, I play a cd and it acts like its skipping,soundwise,but the display counter dissappears with it leaving track number intact and the backlight remains lit. Turn the engine off and it plays fine.
JVC Headunit £80 in halfords
Corsa B type 94 1500TD
Batt 12volts
Alternator 14.3volts
I've wired direct to battery, and to various live points.Tried suppressing with a Cap and an inductor but the same thing occurs.Turn the engine off and everythings fine. I can't return the stereo because I bought it from me brother in law and its fine in his Beemer.Car battery is new, alternator a Recon,the owner,I'm turning into a cabbage with this one.
Help,please anyone
Cheers mikee55:mad: |

| What did you hook up the red ignition wire to? Did you hook up the illumination wire? |

I've wired direct to battery, back of ignition switch outta the fusebox,same thing.Memorey wire goes to Battery. All earthes are clean.

This is how I first wired it.
Damn thing going in bin in a min:smash: |

| All I can think of is the unit is faulty and the vibration of the engine running is causing a bad connection to raise its head. |

Feelin grumpy today, sorry. It was fine in the brother in-laws car.Damn thing. Pc's givin me grief again, though it might be Orange/Wanadoo.IE keeps crashin and Internets slow!, Car stereo burning brain cells and I still got to draw me PCB yet.:hot:

Hi Rich, hope we don't get told off for being off topic. Basicaly I'm in limbo switching from broadband to Live Box??? My account isn't activated but the letter says I can still surf. I'll just wait until they activate me and try again.

hhhm , strange
connect the unit directly to the battery with short wires , turn on the engine and check whats happening . |
|

The original connection was a short 2 core mains lead from battery to the headunit. Not unless you mean take stereo out to the engine bay and temporarily wire some speakers. An update for ya, I'm taking power from a fuse and the earth to a screw nearby. The skipping has reduced somewhat but the front left speaker distorts and the overall volume has dropped a little.:confused:
I'm gonna rewire it tommorow.
Cheers

| You do or do not have the illumination wire hooked up? It should not be hooked up. |

Hi Jexx, Tis hooked up! Next:D

Hi all, I've rewired it this morning. Guess what? It still the same, but...
I disconnected the earth to connect it elsewhere whilst the unit was playing and it kept playing! Its getting its earth from somewhere else and not the dedicated earth wire. I assume the arial and chassis.
Also, I think I should add, the car's original loom was "ISO" I think its called,the stereo isn't!!
Cheers mikee55

The car loom should be ISO. The stereo should have either a proprtietary connector on the back which a loom plugs into with an ISO connector on, or is just an ISO connector already.
If that's all present and correct it should all be fine, with the exception of the red and yellow (permenant live and switched live) wire needing to be switched round.
Hope you have't chopped the ISO connector off the car :o |

Morning Rich,
Tut Tut,Yes I cut the Iso off about 4 year ago. I know, stupid thing to do, but the stereo back then was a Radio/Cassette.I had me meter and wire cutters, away I went. After that I used a portable cd player and a cheapy Boss amp. I didn't think it was an issue. Any ideas???Or is it too late?
Cheers

Even with a radio/cassette it should have been able to connect to an ISO loom, they have been standard for over 10 years now.
Personally I hate butchered things, so I would try and get the ISO back on the car, if it was me. For completeness and ease of connectivity in the future if nothing else.
You never know, but doing this it might all work fine. There may be something that's been overlooked with all the spagetti, bullet connectors and choc blocks in there... |

Well, It would be a nightmare, I mean, are the colours standard? If I went and bought one, would it be a case of matching wires?
Off topic, did you get my images I sent you? Outlook has been on one,Send and Recieve, checks my account twice! and the IE keeps playing up,it hangs quite a lot waiting for a page to open!! If the boards look ok, I'd like to start the Input mixer tonight. What do you think?
Cheers

You can get repair looms from Halfords and car stereo and accesory shops, for that sort of thing. Or maybe easier is to visit a scrap yard and cut one out of a similar age Vauxhall.
Yes the wires are largely standard colour coding. The 'power' section is anyway. |

| The illumination wire should NOT be hooked up. |

| Really, it has been on the three of four stereos I've had in my car, with no issues. It's how the display dims when you switch the headlights on. |

It's nice to have when done properly, but in the world of DIY head unit installation, it usually gets hooked up to the wrong wire(or doesn't function well with the existing illumination wire) and isn't necessary anyway. |
