Which Isolator Switch

[reelchippy]

i would say it is the same wiring as the 721 , should be 3 poles on the rear of the 701 .

Yes same hope the switch can handle it motor is only 50hp

Northernblue - you need another isolation switch on your accessories battery. Our boat has isolation switches on each engine battery, an emergency parallel switch to link the engine batteries, and an accessory battery isolation switch.

If you need to charge off the port motor in an emergency can you use the emergency parallel switch?

We also have a BEP VSR which isolates the accessories battery from the engine batteries when the motors are off so you can't drain the engine batteries using the accessories.

Krillx, at present I don't have a dedicated accessory battery, and the port motor does not have a charging facility/alternator, but I can [probably will install one].

I havent finished reading the thread yet but it seems that a few of you are happy with these units

The BEP VSR (Voltage Sensitive Relays) are the ducks guts.
You can get them in various configurations. From an auto which only controls the volts but has not isolator switches, to the ones described above (these can be in a couple of sizes eg 4 in a square or 4 in a row to suit different installations), to a remote operated setup where you mount the switch on the console & it electrically turns the isolator switches for you.

For anyone with dual battery setups a VSR is a god send!
