Headunit don't like cds when engine running!

mikee55 · 5th November 2006, 03:38 PM

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

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.

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.

Are you running a firewall on the PC?

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.

Cheers Mike
