Thread: Overcrowded Battery terminals

With the positive lead it's not so easy as the "bolt" is part of the harness that runs to the under bonnet fuse box. Is there a different kind of terminal or some way of connecting all the accessories?

Visit an extreme car sound shop, the little boys use gold plated terminals with heaps of outlets

Have you considered leaving the winch and one additional 6mm copper core cable which goes to a 20A, 40A or 60A circuit breaker on the battery terminal. Then use the circuit breaker terminals for all you accessories?

That's a bloody good idea. The HID and headlight relays are individually fused so I could safely use a 60A circuit breaker.

If you have individually fused accessories, you can also use the battery side of the circuit breaker for additional accessories. Although that said, I like the idea of a breaker or fusable link before any accessories.

This one gives you a couple of extra outlets...........

Freaky Joel, i was just thinking about this yesterday, i have the same problem and about to add more acc, so the terminal is running out of space.

I would favour putting in a mini fuse box.

There are numerous types available from the big electrical manufacturers like Narva, or check out the marine suppliers. I think Jaycar have several.

I purchased my last one, from the local 12volt shop. I used 6-8mm cable to feed both positive and negative current to the fuse box, from my dual battery.

All the accessories bar the s/lights were then wired through the box, and individual fuses suitable for the accessory in question were used. The main feed to the box was routed via a resettable circuit breaker.

The options are endless, and everything is well controlled. It is also surprising easier to wire everything to a common point and use spade type terminals, rather than trying to size everything to a battery terminal bolt.
