Well I did a quick check over and apart from the Radio (which can be a bit iffy anyway) everything worked, i.e. heated seat, lights, windows, wipers etc. After connecting the Battery, I put the key in the ignition and the Speedo and Rev counter did a full sweep, which is what happens when trying to start when the Battery gets flat, only this time it cranked well and started straight away. The Heater Plug light didn't come on, but it started fine all the same. I was going to try putting the 'Fuse' back in, but it was a lovely afternoon and I didn't have the nerve to upset the locals , however I will go out over the next few days, and try it putting it back in when I find a quiet spot. I'm still wading through the mass of light bedtime reading a.k.a the links to the manuals
