The vans a non starter (2l a/c), turn the key and nothing happens. The solenoids on the carbs click but the starter doesn't spin. On top of this, the wipers are dead slow, lights dim in seconds when I put them on and when I put the hazards on there's a nasty sound from the relay like its sticking. The battery has a good 13 volts or so.
Think this points to a bad earth at the battery lead but I had a poke about in the dark

Could anybody let me know if there might be anything else to look out for?

I'll put my member no on my profile once I've found it.
