Installing a Car CD Player

[MarieCeleste]

Hi

I am connecting a car cd player into the boat, and have purchased an ISO Connector which shows me which leads are positive (there are two as one is for the ignition) and negative ground - which I guess is the minus side of the battery.

When i connect the positive and negative terminals on my battery nothing happens?? The unit does not come on?

I am connecting both positive leads together to the red side and the ground to the black side - any thoughts??

The battery is connected and other circuits work fine.

There is usually a spade fuse at the rear of the stereo near the connector socket, this may have blown. One of the positives is for retaining the settings memory and should be permanently live, the other normally goes to ign.

Are you trying to install in it's final position? if so check there's 12V coming out of the cable to the power source.

Is the stereo new? have you seen it working recently if not?

sometimes there's a fuse in the back of the stereo which can't be taken out without removing the cable loom, check this is intact.

are the contacts on the removable faceplate intact and clean?

Hi Thanks for the replies so far:

Yes the ign and permanent positive are joined and both connected together with the positive feed from the battery which is live.

The spade fuse is fine and unbroken.

The stereo is new and so connections are clean and I have seen it working in the shop.

STILL a mystery then? /forums/images/graemlins/confused.gif

check that the pins on the iso are actually wired to the same pins as the ones on the stereo socket, I think on Vauxhall leads you have to change over the red and yellow wires. Is it a face off type, if so is it fitted properly

If it has a removeable front panel for security, make sure it is clipped firmly in place.

When i put mine in i had the same thing and it needed 12v on both inputs to start up.

Resolved - NEVER use Scotchblock connectors, the ones that apparantly cut through the insulation themselves.
