Removing the old units

So it's starting, weather not been great but I've removed the old units on both sides of the van, and boxed up what I can whilst some things stay in the van. 

Ordered a new Sterling Power battery monitor, this one has built in MPPS controller for the solar panel and also looks after the stop start/ regenerative braking system. The old one does the job but not quite, more suited to the pre T6 fancy electrics.

Also fitted a new main battery 85 amp suitable for the van but old OEM was only 65 amp. Bit of a squeeze but got there.

On that note:

To be able to change the battery yourself you need to keep the 12v electrics working whilst you change over. A search in YouTube found the way, quite simple really! A pair of jump leads and a slave battery! 

Connect jump leads to the main battery terminals and the corresponding slave battery before removing the main clamps from the battery, be careful to isolate live terminal I used a rag. Remove old, insert new, hook it up then disconnect the jump leads. Job done no loss of info and all instruments/ radio/ windows all working perfectly.
