Hi Peterd - you are a very lucky man! On my 2003 Plus8 I could not go more than 2 or 3 weeks without a recharge for the vehicle battery. In fact, I decided to remove the Morgan clock and keep it on my desk (powered using a small ac-dc converter) because it is so far over on the right I could not really see it. In its place I fitted an ambient temperature gauge so now my wife knows what to wear..........This is also how I got the cigarette lighter socket to light up as there is already a wire to the clock for illumination so you can splice into that - on mine the socket already had the light and connection, I don't know why Morgan didn't connect it at the factory
