Hi Apologies in advance as I'm a newbie to this site and to LR in general. I have a series 3 LWB, which has been modified with a LR 110 chassis. It started as a project but now a chore It has an electrical fault due to the amount of modifications by previous owners. The battery is being drained and not recharging. Can anyone give me an idea of how much it would cost to re-wire by a professional? Thanks
