Thanks Fred hope you are both well.
I’ve removed the EBL and the type is on the back grrrr. Type G.
I’ve emailed martin at A and N. Hopefully I will have them repair it. Apparently they have no problem with the 18Amp versions which this one is.
There is no continuity between the 2 pins so there must be a burn out there.
It all works except for the starter battery indicators but I don’t feel safe using it with a fault.
I hope he can look at the LED panel as this may be causing the fault
Keep safe
Tom
