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 ?
