Today's little project was installing an earth bus in the battery box.
One of the issues is all the lug connections everywhere. The starting battery negative terminal is probably the most cramped, with 3 lugs stacked on the 1 post. Not bad, but not ideal either.
The little job today involved bolting a Blue sea systems bus bar to the inside front of the battery box. You can see it on the top left of the pic below:
This bus bar was a spare bus bar from the ex box project that had been clogging up the parts cupboard at home. So this was put to use in the battery box. The unfortunate thing about these 'never ending' projects is that I often hang onto too many things after they are removed, or don't plan properly and over-purchase parts or end up changing my mind and not using them entirely. My 100+ trips to bunnings, and a case full of nuts and bolts are testament to this phenomenon.
The bus bar arrangement will also help me trouble shoot a bit of a bug I have with the existing setup- for some reason, when disconnecting the starting battery from the main power feed (to the starter motor and fuse block), the aux battery is somehow powering the dome light... so there is power leaking between the 2 battery systems somehow... I ideally want the systems to be isolated from each other, with only the ACR (charging relay) being between the batteries. Any ideas on troubleshooting this would be welcomed!
On a plus side, having the earths laid out on a bus will mean that I can disconnect one lug connector without having to remove the whole stack of earths. Plus it will look neater, and pull more babes.
Some might ask why I am back to old tricks messing about in the battery box...
I'm making some changes in this area to accommodate a new electrical addition in the engine compartment. It's still in planning, but I will be installing a headlight wiring relay kit, plus an additional (small, max 4 circuit) fuse block in the engine bay for incidental additions in the future. One of the goals with the electrical mods was to make easy access to points of power and earth for future additions. I've got this squared away in the ex box, in the rear speaker panel, but the engine bay is the only place that I have not yet molested with additional wiring. I am looking forward to tidying up some of the previous spot light and LED light bar install work that was done before my purchase of the vehicle. The tell-tale bundles of wires zip tied and stuffed into odd places are still there, as are the scotch locks on the headlight circuit to power the in-cab switchgear.
Wish me luck... there is not much spare space in the puma engine bay...


Keeping it simple is complicated.
