Spur flattens battery, central locking I think.
So, my father's 89 Spur ii had a flat battery, I fitted a new one and when connected I heard the locking "clunk"
Two days later and the battery is flat. I notice that the passengers front door does not lock, the button moves down but returns slightly. I suspect this door is causing the battery to drain. What's in there, what should I look for.
Thanks in advance.
