Between the rain showers this afternoon I was able to have another go at this problem.
I put two batteries in the starting circuit that I know are fully charged and attempted to turn over the engine without success. However I did hear a relay clicking when turned to start - I kept at it and after about 30 secs the engine turned over.
So it would seem the issue was a combination of poor battery power and some moisture on the contacts in the relay. There was not enough oomph in the starter batteries to make the relay click previously so decent batteries seem to have made the difference.
I will need to get my starter batteries to auto elec for checking and knowing my luck spend more money on batteries.
Thanks the help and comments
