Redarc Smart Battery Isolator intermittent switch wiring

[rannon]

I said to heck with it, and neutered the SBI so it is just a starter relay.

I could have saved $120 if I just bought a starter relay in the first place.

It works fine for jumping with the trigger being the positive wire from the Switch-Pros. When power is applied it connects the batteries. No power applied, the batteries are isolated.

The BCDC takes care of controlling charging of the auxiliary, and isolating them.

Hopefully I didn't do something stupid. The good news is that I could put it all back together quickly if needed. Nothing was altered or damaged when removing the smart bits.

The part I removed:

So I want to install this same isolator - and regarding this blue wire switch; my question is if I connect a simple on / off rocker switch to that wire, will it accomplish the function of the override? Or does it have to be a specific momentary switch? Definitely a noob question I know, but really want the in-dash feature here. Thanks!

An on/off switch will do the job if all else is wired correctly. I used a momentary function of the Switchpros, since I am only using it for self jump. I would also not like the possibility of human error leaving them (on) linked and letting both batteries drain without protection.

Very good point - and thanks for the reply, I appreciate it!

One more quick question regarding the switch! So if I went the on/off route, with a 5 pin rocker for example, would I need to also ground the switch? Or is it enough for this application to just use two of the terminals for power in and out to auxiliary load? Thank you!

Apologies, but I don't recall how the trigger is wired.
