I keep losing programmed radio stations every time the car is turned off.
I've used the wires that power the cigarette lighter to run the radio. The previous owner has butchered the wiring & can't be sure what wiring is correct.
The car is a coily & the radio that I have replaced had the same problem.
It's is driving me mad as I've tried every available wire combination.
Any ideas what might be causing the problem?

You need a constant 12v supply not one off the ignition. There should be one there already, otherwise try wunning one off the clock.

you need to find a constant power to go to the yellow wire on the sterio. SJ70s I pick power up from the back of the fuse box, usualy interior light or brake light fuse,SJ80 should be much the same. That will rectify your problem

check your ground aswell man, i had the exact same problem. usually my radio had like a 2 sec delay after i started the car. I use a sony wiring harness in mine and it was a white wire with yellow strips on it. Check that out... hope this helps man

you wired the constant +12v and the ignition +12 around the wrong way is my guess. i did that when i fitted my new stereo and it did exactly what your saying...

You need the White with Yellow wire which is constant 12v to the yellow wire (usually) on the radio, then you need the white with black (accessories) to the red wire (usually) on the radio.

mate ive spent the last three days wiring my sound system in on my leafy and my previouse owner was an absoult butcher with auto electrics.

so when installing a sub, amp and deck, aswell as 6x9s and 6.5s i have finaly got it all done i used a sony wiring kit for the amp aswell. so im guessing u have already replaced the speeker wires.

dont worry about using any of the wiring harness strait to the deck. your trying to run a deck that puts out 200watts (in my case) of a wiring harness that would normaly run an AM or possibly a tape deck in ur case radio, as a result it wouldnt get enough power and cut out.
so to fix that problem i tapped into the ignition wire about 10cm from the ignition barrel (i had to replace all the wire around there aswell due to previouse owners but u shouldnt have to) the wire u want to tap is white with a black stripe. run ur tapped wire (i used 3mm) to a relay in behind ur deck as an activation positive. then run a nice fat wire to the batterie as a power wire for the relay. obviously run a decent earth wire from the relay.
then from the power output on the relay into the red wire on the deck. this replaces the accessories wire that u have pulled from the cigeret lighter and that now activates the relay.

finaly that was all good and the deck wouldnt cutout anymore at high volumes or when brakes hit etc (the brake lights and clock and cigeret and deck all run of that same white with a black stripe thats alot of stress on a 2mm wire)
my next problem was your problem. this time i tapped into the "hot" wire on the relay and ran it strait to the yellow wire on your deck. then use the good solid earth u made on the relay as an earth for the deck aswell by running your deck earth into it. after doing this you will have full 12volts to your deck as an ignition wire (it runs of this) full 12 volts as a power wire (runs its memory of this)

lol now i have the problem that my alternator dosent put out enough power to run my amp at full power its never ending

in my case i had a kenwood deck. and yellow is constant power. and red is powered when the igntion comes on.

i know it sounds like alot but i spent 2 good day i recon atleast 6 hours it took me maybee 2 hours to re run all the wires once i bit the bullet and did it all again i would realy suggest u do it. how i mentiond above.

idk what ur previous wiring was like but heres what mine looked like. those wires run to the ignition barrel and were TWISTED together.



here is the clip that is ment to join the ignition barrel into the cars wiring harness i love how he has run two wires instead of one thick one for like 3cms




needless to say my barrell is now soldered into the harness lol

Got it going.
Glad that's over.
