Car Forum / Alfa Romeo Cars / December 2007156 - Any accessory power available....
...in the radio area. Last time I had a look at replacing the radio I couldn't find any convenient accessory 12v power. Seems to me there's only ignition or permanent 12v. Permanent is obviously needed to retain the memory but ideally I'd like accessory power for the radio. At present it uses ignition 12v, which is ok...mostly, but if I'm working on the car, or waiting in it for any reason (usually waiting for the missus somewhere) I don't want to be leaving the ignition on to listen to the radio. It used to have a permanent 12v which was a nuicance having to turn the radio off every time I got out of the car, so last time I changed the radio I went looking for accessory power but could only find ignition back there. So, is there accessory 12v nearby, or do I have to get the steering wheel cowel off and splice in to something around the ignition switch?

IIRC there are red and orange leads in the ISO plug. One is permanent and one is an un-used (at least on the S1 Alfa Stereo) switched live. Red is I *think* switched, Orange permanent. Failing that I connected to a switched live behind the fuse cover for some bits.

Hmmm, I now remember the problem I had last time, there doesn't appear to be an 'accessory' position on the ignition. There's... Park Stop MAR AVV ..bugger, ah well, back to having to turn the radio on/off manually Thanks for the reply, enjoy what's left of the holidays. Heard a good un the other day. The makers of Tampax tamons have replaced the string with a bit of tinsel.... just for the Christmas period.

It's just a wiring issue. <snip> ;) SignatureCatman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) 116 Giulietta 3.0l Sprint 1.7 145 2.0 Cloverleaf 156 V6 2.5 S2 Triumph Sprint ST 1050: It's blue, see. www.cuore-sportivo.co.uk > Mine comes on at MAR and goes off at stop. > It's just a wiring issue. Yeah, but isn't your ignition on in the MAR position? Mine is. Don't want to be leaving it like that for any length of time.

Probably a hangover from the days of carburettors and electro-mechanical injection systems, where you could burn out the coil by leaving it energised like that, without firing. On an ECU controlled car, it's not a problem.

Er...yes, that's what was on my mind... Didn't know about the advent of ECU systems resolving the issue Ta Alan >>> > Yeah, but isn't your ignition on in the MAR position? >>> [quoted text clipped - 17 lines] > >Alan Ah ha! All becomes clear. What a jolly useful place a.a.a-r is. Rounding out the year with another problem solved and helpful tip for the Google searchers of the future.
