Solar panel issue has been fixed:
The silver foil connectors in row 4 of the nearside panel had delaminated causing open circuit in that row this led to no voltage getting to the controller and hence no charge.
I removed the backing and took apart the panel, re soldered it and covered the access point in sikaflex to re seal.
So far working as good as ever
I have now added labels to the control panel pictures to follow.
I have purchased two new rear wheel bearings and handbrake shoes to overhaul the rear end as I noted a squealing noise from the rear wheels, I changed the discs and pads about 10k ago so a wheel bearing is the likely culprit.
Again I will post pictures when I get to do it - probably saturday.
I am investigating fitting roof lights and vents will update on this shortly.
