Sorry i didnt update but having messed about for ages until i was really late i decided to jump in the milk float and go anyway, i saw lots of classics going the other way having left Towcester going home. So, what else can go wrong?.. well, Teslas may have a lot of computing power but they still aint smart enough to know that the country lane i was on leading to Towcester is closed for roadworks at Shutlanger. Following a big detour i finally got there to a half empty showfield. Chatted to Mr & Mrs Chuffer, a quick look around, met Letank and his Red 73 and its time to go home again.
Oh yes, my Vette, i took the 12v battery out of my other milk float (eNV200 combi van) and connected it up using jump leads, no joy. Having disconnected it again i then noticed that when i turn the ignition on the Vette voltmeter was only reading 8 volts (why didnt i check that earlier). Chuffer was right, new side post required.
