Has anyone in here done the twin street conversion ?
On my Mk7 it was straight forward,
but on the custom it has a +red diode with loom dissapesaring back sat above where the second battery goes,
Any pointers ?

Job done

The stop/start systems use AGM batteries that will do deep cycle and high current. The standard single battery even with two of them will be killed quickly running inverters or lights for long periods.

Yeah that's why I didn't connect the diode because that's something to do with the smart system with regard to the easy start but already on fitting the new battery I've noticed that when I start my van now the stereo doesn't go off which means it's not dropping below a certain voltage.
So Happy days

Had a few Fords and their batteries now.......and they are never right once they have lost their charge. They never seem to fully recharge again. The average life of the silver calcium Ford ones seem to be just around 2 years. I had one fail just over a year old on a Galaxy. Even a Euro car parts cheapie was better than the oem Ford battery.
I hope the twin battery solves your issue though.

Sadly Dave I don't think the "Happy days" will turn into happy months, It sounds to me like your original battery is goosed and it will shag the new one, long term it would probably be better to just replace the old battery.
