Radio wiring probs

[daddy cool]

Have 6 leads going to a multiplug for the radio (not speaker wires).
In plug order:
1. Orange/black trace appears to be permanent live
2. Brown/green trace appears to be an earth
3. Yellow/blue trace appears to be switched live
4. Green/black trace appears to be live with lights on
5. Black/yellow trace ?
6. Brown/green trace appears to be earth
Does anyone know what sort of voltage I should see across the leads? All the lives are about 10 volts
No other electrical problems except fuel gauge is always on (Probably supposed to be I don't know ) and the temp gauge reads ok with the ignition on but stays where it is when you turn off the ignition, until you turn on the ignition again when it then reads correctly again.
Hope that made sense! Any ideas?

Are you trying to fit a new stereo? If so i'd just buy an adaptor lead if I was you!

I did that , makes life alot easier and saves alot of time

[daddy cool]

Bought the proper (I thought) ISO lead when I first got the van so I could fit the pioneer player. That worked fine. The new one loses it's memory when switched off as though the permanet live isn't connected. The two live leads are bulleted with the idea being on some cars (Vauxhalls)you have to switch the lives over and there is also a double connector on one of the live leads for Audis as you have to join the permanet and switched together Have tried all three possibilities but still the same.
Will have to have another look in the light tomorrow

Everything you've listed is right, the Black\Yellow goes to the security module.

As you keep losing all memory of the stereo I would say your switched and permenant lives are the wrong way round. Has the stereo got a yellow and a red wire? These will be the switched and permenant lives, not sure which way round though.

[madvanman]

yellow - permenant live
red - switched live
on most makes of head unit
some pioneer units had orange as permenant live (usually the older ones)

Made a schoolboy error

The ISO lead I bought fits Transit and a few other Fords. The speaker multiplug is a perfect fit. The power multiplug has slots for 8 pins. The corresponding radio plug has 6 as stated above and is not exactly the same shape as the ISO plug! I managed to connect the lead 2 pins out, which was why the permanent live wasn't working (excuse the basic drawing)

Still it works now

[MrMPuk]

Lucky you didn't kill the stereo then. Sounds like a dodgy ISO lead to me as it should have had the knobs on the side of it so it only lines up in the right position.

Glad you sorted it though.

[daddy cool]

Ok have been trying all this while to get this radio sorted. Have finally wired the switched live to the permanent live so that the radio works independent of the ignition.
Having a strange phenomenon with it now that I hope someone can explain . The radio keeps all the programmed stations overnight as you would expect, until I turn the key to the starter position. Van always starts within a second but in that time the radio switches itself off and loses the stations. Only happens first thing in the morning. No matter how many times I start the van or turn the radio on and off during the day, it keeps the stations until first thing in the morning!
Any ideas?

[MrMPuk]

What you've done is switch the permanent live and the switched live so that you can have the stereo on all the time right? Because you've done this the permanent live that the stereo needs to save the stations is no longer there! So you either need 2 permenent feeds or swap the wires back.

[daddy cool]

Split the permanent live so it feeds both

You have or you will?

[daddy cool]

No I have!

My van used to do exactly the same thing (even though its 15yrs older) until I changed the loom when doing the auto conversion, since then its been perfect.

The only thing I can suggest is that you take a feed directly from the battery through a seperate in-line fuse.


Rover.

[daddy cool]

It's weird though because it worked ok with a Pioneer player in it.

Yeah I came to the same conclusion about the direct feed.
