If an alternator was connected directly to the batteries, then for it to pass a Boat Safety Scheme examination it would be necessary to fit a suitable fuse in the circuit and also to provide written evidence from the manufacturer of the alternator supporting the decision to by pass the main Isolator. Richard you are very wrong and should not be giving advice like this until you better understand the requirements of wiring on boats which come under the requirements of the BSS. My question is simple, is this right? Or should the 2 pole isolator, actually be a 3 pole? However this means that when the switch is turned off, the alternator is still connected to the batteries, so if the engine runs, it is still charging, and if the engine is not running, there is still a 12v feed to the alternator. The alternator and battery both go to one pole, and the load goes to the other pole. The engine has 2 alternators, one for the engine battery bank, and one for the domestic.Įach circuit (engine and domestic) has a battery isolator switch with 2 poles, so effectively te switch either makes, or breaks the circuit between the 2 poles. I have noticed however that the 2 battery isolator switches do not fully isolate the batteries. This has had the desired effect, and the electricity reliability, especially the 240vAC is significantly better.

He has changed from 3 x 110Ah Batteries, to 3 x 225Ah batteries. This can save you money in the long run and give you peace of mind knowing that you have taken the necessary steps to keep your car running smoothly.I have recently helped my dad replace his domestic battery bank.
