Chris, I have finally fitted my PC925 including the cleaning of the positive terminal area below the washer bottle. This appears to be a junction for a number of leads, including the positive cable running to the starter. There was some sulphur build up on that connector which may have been unhelpful.
The car started with a very lively turn over with the battery straight out of the box. I have put the battery conditioner, CTEC, in place with the setting for trickle at the highest, hopefully it will survive for a season or two.
Dave
