Hello world!
I'm sure this is a stupid question... but I've been in my car with a volt-meter for 1 hour, and googling for 2!
I removed the original radio, and tried to replace it with a newer radio from my ( now scrapped ) polo.
The newer radio has a different socket type at the back.. but hey, no problem, it came with an adapter.
One half of the adapter has all the speaker wires.. and the other half, the power. the pins were in the wrong positions for some of the pins... but i have some pliers... so no problem there.. i just need to know where to move them to..
so... time to whip out the trusty volt meter.
I have 3 wires to figure out... ( ground is obvious )
the 3 unknows should be bat+ / vcc+ and remote.
one wire shows +12 volts ( regardless of ignition )
tha must be the battery... one of the other wires varies rapidly, between 4 and 5 volts.. regardless of ignition state. and the other wire varies rapidly between 0.4 and 0.6 volts.. again regardless of ignition state!
I was expecting one to be +12v ( always on )
one to be +12v ( only when ignition key is turned )
and signal to be 0.. ( or close to zero )
Whats going on !?
I gave it a few guesses, and none of my spare car radios would power on, with all possible wiring configurations.
all fuses are good!
And all my spare radios are tested and working fine in my boyfriends car!
I guess the grande punto's radio is completely non-standard !?
is there any hope?
some secret 3rd adapter i need ?
THX and sorry for being soo damn blonde!
