G'day all,
I'm in the process of installing the second battery in the patrol. The unit of choice is a DBE 150S from Piranha, which I picked up from a mate as he had upgraded to a full on board battery management system.

The problem that i'm havinig at the moment is finding a suitable place to earth the second battery to the engine. What have others done in their patrols?
For now I've only got a ~60cm long earth cable, but am tempted just to run it back to the negative on the main battery, which is already earthed to the engine from there.

What have others done in this situation?

G'day, second battery is earthed to the lifting lug at the left hand front of the engine and also to a bolt on the inner guard behind the vacuum cannister. Bolt may not be there, but nut is. From memory it is a 10mm bolt. Hope this helps. John

G'day mate

I have earthed mine back to the exhaust manifold bolt on number 6 cyl I thought I may have had trouble with heat but has been perfect for over 5 years.

GU's need all the earthing they can get. I''ve taken mine back to the cranking battery and added another earth to the chasis as well.

I've earthed mine to one of the bolts that secure the AUX battery cradle (ARB one) and also another short earth from the cradle earth to the earth on the alternator.
