After two full trickle charges and drop tests, and a further full charge the batteries have been given a clean bill of health.
A connecting cable between two of the leisure batteries and the third was found to be of inadequate cross-section and replaced.
The battery selector/isolator switch was found to be incorrectly wired and not isolating anything!
All systems have been checked and SONFLOWER has been returned to her mooring for the remainder of the winter.
Thank you again John and Tooley's Boatyard
