Leisure battery wiring

[triggermala]

Hi I have purchased a VSR split charge relay kit and new leisure battery. I am having trouble finding a good earthing point. I have put a meter on a few areas which have bolts into the chassis but only getting 1 on my meter is this correct and ok to connect my earth wires from relay and leisure battery to or should it read 0.

Hi. I recently bought one from 12v Planet and used their video below to help me install it.

If you skip to 15 mins 29 sec you'll see they show the earthing wire connected to the leisure negative, although the text says it should be earthed to a common earth point or the starter negative. If you lift up the carpet/rubber between the cab seats I think you will find a screw that acts as an earthing point about 6 inches from the step down into the main area.

I didn't pay enough attention when I first watched this vid and have the earth connected to the leisure negative - think I need to revise this!
