Swapped out the original faulty 1960’s Lucas alternator for a modern equivalent. No heavy demands but the boat has 3 battery banks with a dedicated battery to supply the bilge pump in the hold. An Adverc is also fitted to compensate for the voltage drop with the split charge diode and all the battery, starter and alternator cables are replaced at the same time. The original alternator had a battery sense connection which the Adverc replaces.
