Spent all day yesterday swapping systems.
650 from my transit to a mates transit
then his 500 into my replacement Combo.
had signwriter do his stuff whilst all this going on
then spent a few hours redoing the wiring, got rid of all the dodgy scotchlocks etc and soldered all the jonts and replaced some lengths of wire all together as that many joints
got roof bars to sort out and get interior trim back in that I removed to hide wiring to battery - twin pumps - one to van battery and one to leisure battery.
