12v Cigarette Lighter Low Voltage

Hi, I have a 2010 Freelander 2

The most forward 12v cigarette lighter port / socket (the one live on ignition).

Randomly it runs at 7 to 8v for a few mins before going back up to normal voltage. Does not happen every journey.

The other cigarette lighter port which is always live always has the correct voltage.

I have changed the 45 fuse under the bonnet.

Anyone else had this or any suggestions.

Thanks

Probably dodgy connection, not directly commenting on voltage, but may help narrow down the issue: https://www.freel2.com/forum/topic33954.html

Are these voltage readings with or without a load on respective circuits?

That is, are you using a modern (high resistance) meter, and do you have anything plugged into these sockets when measuring voltage. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)
FL2 Metropolis SD4 Auto 2014 2017- (16k - 82k+ miles) (MY2015)

High resistance somewhere - eg corrosion, damaged lighter socket, poor earth , damaged wire.
No easy way to find out - have to test along the circuit.
Has something been spilt into the lighter socket. Jules
