This is fine when the van's running BUT I think there's a co*k-up in the Leisure Battery wiring and so it's either - or possibly both - (a) NOT charging on a split charge as it's supposed to and is instead charging in parallel; or (b) drawing charge from the MAIN BATTERY once it's drained the Leisure!
I know I'll need someone of an electrical bent to look over the wiring (totally beyond me, I am a dunce!) but what I'm wondering is...
(GETS TO THE POINT AT LAST)
What mini-fridge/coolbox solutions do others have AND how do you power them AND do you unplug when you're parked up?
Cheers very muchly.
