When you do wire your alternator direct to the house bank please consider installing an alternator service disconnect switch.


This is a switch placed visibly in the engine space so a service technician can isolate the alternator from the battery bank, while working on the engine, without having to remove a fuse to do so.


This is a Blue Sea Systems m-Series #6006 battery switch in the positive alternator feed. This switch is rated for 300A continuous. During normal use this switch always remains in the ON position. The only time it is turned off would be when a service technician is working on the engine. I prefer to mount this in the engine space so it is out of sight and out of mind of guests on-board who were; "just to trying to help.".


Please remember that any wires leading to the house bank will get fused at the banks positive terminal or within 7" of it. This includes the alternator B+ and regulator positive volt sense wire. The alternator B+ feed should be fused at a minimum of 150% of the alternators output rating.


Wire safe, wire well and your system will perform as it should.
