So to continue my RedArc Dual Battery Setup, I’ve now wired up a little LED on the dash board that tells me when it’s activated and passing power to the auxiliary battery. It is a very simple task to wire it up and it’s part of the standard features offered by the RedArc SBI12 Dual Battery Isolator, and the wiring instructions can be found in the RedArc Isolator instruction sheet provided with the product.
It’s a very simple matter of connecting the override cable to the + side of an LED, earthing the LED and then drilling it into your dash.
I purchased a length of double speaker cable from Bunnings for this job, and borrowed my dad’s soldering iron. Now here is a tip for you… When you’re working around your engine, be patient and let the engine cool down first. I learnt that from experience… But after my trip to Bunnings I was all keen to get started.
I also purchased a 12v red LED for the dashboard. I bought a 12v LED because otherwise I’d have to purchase a resistor for when I install the override button as well. I think I’ll install that under the bonnet rather than drilling a big hole into my dash.
I decided that the simplest place to earth the whole setup was back at the same place I’d earthed the RedArc Dual Battery System Isolator earlier. And that’s part of the reason I bought the double speaker cable.
The scariest part was drilling into my dash board! Not that it was hard, but that it is very visible. You’re drilling into your dash board! Once it’s started you can’t un-start it!
Anyway, all went well and now I have a very cool little LED that lights up nicely when the isolator does its thing.
