In that case, here you go... http://www.ebay.com.au/sch/i.html?_...c1240lv&_osacat=0&_trksid=p3286.c0.m270.l1313
If I recall, the isolator should be placed in the engine bay. There is a distribution frame behind the battery which should have ignition-on power source.
I've mounted mine in the tray near the second battery.
There is a green wire coming out of your alternator (there is a thread somewhere on here on this subject) that controls the low voltage operation.
Snip this wire, and you have a constant 13.6 -14V all the time.
I did it on my 2011 D40 STX and the aux battery in the tray is fully charged all the time now. Problem solved.
i spoke with my fried at redarc today, That bloke knows his stuff!!!
he confirmed for me that the 2011 STX550 was the first to receive the alternate voltage alternator, and the later i.e 11/12 model St and STX started getting them.
he told me to Use the scan gauge (if you have one) to test weather or not you have one simply by driving the car until its warm (obviously with the VLT setting on the screen) and floor it, watch the volts and if they drop to around 12.7 your in need of the BCDC 1220IGN or the 1240LV
I take it that if in doubt you can use the BCDC 1220 IGN anyway? (New D22)
That's the idea.
I'd already bought a 1240 before finding all this out.
Thanks Mike, looking this weekend. Did you buy online? I am concerned with warranty
