| stereo changed start error!!!
where do i start
im loseing my hair lol.
I bought a 2000 a170 a week ago and it had fitted an after market jvc cd player that did`nt work properly.
everything else was fine.
whilst waiting for the insurance paperwork to come through i put it on my parents drive,
in the week i set about changing the stereo, i was a mechanic of 10 years and i have alot of experience in ice too.
when i removed the jvc it was a mess to say the least wires and block taped in everywhere.
now with hands up. what i did was do what would have been professional in my day, i stripped the loom back to standard wires and wired in the new stereo.
found my earth and posatives ect speaker wires.
when i had finished fitting the unit i had alot of wires left over
in the process the battery whent flat!
so i rang mercedes as i had herd that you cannot jump the A class i was advised to trickle charge the battery over night off the car.
i did this and the battery would`nt hold any more than 7 volts so i bought a replacment battery.
after reconnecting when i tried to start the car i got the start error on the dash.
i have seen mean reasons for this BUT
i have alot of wires behind the stereo that are not connected to anything,and i can`t find out what they do.
does anyone have a wiring diagram for one of these or a knowledge photo of the rear of the stereo.
i have spent all day on the phone with several people and there wire colours don`t match up with what i have
i have
pink&brown/pink & white
green&brown/brown
brown&white/pink & white
brown&red/brown & black
which i have set as speakers
lareg gauge brown (earth)
pink and blue (battery constant live)
large gauge blue and white (??? tele mute???)
small gauge blue&white ???
small gauge green&black (has ignition live)
large gauge pink&white (has ignition live)
small gauge pink
if anyone could shed anylight i would be so appreciative.
many thanks tony |
