Have been getting odd clicks from the electrics when starting recently, so replaced the ignition switch with one I got on ebay - problem solved!
The other issue I had with the old switch was that when I put a new keyed barrel into it, I would sometimes pull the whole barrel out with the key. Stuffed around with it for ages and could not get the new barrel to stay put. I guess there was some wear in it because it now stays in place in the new switch when I pull the key out.
Now to put a cubby box in the center seat section.
