Theres a good chance tht you voltage regulator (mounted inside your alternator) is breaking down under load and perhaps your battery charge rate is suffering too.

A simple test (with a multimeter) is to check your battery static voltage - it should be ~12.6v cold - then check the charge voltage @ +/- 1,500 rpm which should be 13.5 - 14.5 v.
This is just a general test because the alternator could be breaking down under load, in which case you need to conduct load tester to your alternator......

You have the same issues when a battery charger is connected to the battery?

Hi Jager,, Yes same problem. However !

My Wife has gone out to play at the shops, so I'm left alone to do some serious tinkering !

I thought I would start with a proper look at the Current distributor - I'm glad that I did. Every terminal an nut had light corrosion on them. I removed each link and cleaned every terminal, link and also replaced each nut with a nice shiny new one ! I then went to reconnect the Positive side of the Battery and thought I would cut off the sleeve at the Current Dist' end I'll say no more .. See below.

Hopefully once I've replaced the Cable my problems 'might' be solved ?

Thumbs up

:dance: Radio and Lights now normal !!!!!!!! I'm thinking that the main culprit was the Current Distributor but I guess it could have been a combination of both.

Hope this helps someone else with the same or similar problems.

Glad you found it. If you were having the same issues with a battery charger on the battery it had to be something major like a main cable break-down.

Happy Boxstering!

I'm surprised you were able to start the car.
This cable was probably getting very hot with every start.
