Split charge (re) installation

[Chris]

Yep, ran complete pos and neg cables. No other attachments en route. Always told to keep it a closed system. Avoids any leaks that way.

I used to compete in stereo competitions, on a break at the minute from them.

We used get marked on wiring and had specific rules/conditions, more to help/entice people to do installs to a good standard, lerge cables, proper discrimination with fusing, terminations etc.
never said anything about running a neg adn positive to 2nd battery in the back, always happy use the chassis as a common point.
But on the bright side, if you fitted another battery you could always go the other way!!!

Hope the wagon performs for ya when testing!!!
Have fun
