While on shorepower or the generator all is working well but when our Balmar alternator was out of order we could not use any of the 24volt systems under way.

That means Raymarine main navigation system and radar,comnav autopilot and domestic systems like fresh water,toilets,fridge and fueltransfer.

In the unlikely event that servicebattery system as well as the engines 24volt alternator goes down the boat becomes dangerously crippled under way.

Checking the systems as well as the bowthruster after firing up the system was a joy .
