Hodge's Dual Battery System

This is what I just drew up quickly. Would this work ????

It will, however when you turn your work light switch "manual switch" on your reverse lights will come on

[megatexture]

One rocker switch on/off/on or on/ on would stop that rather than 2 individual switches

Yeah I just realized I didn't quiet draw that well. So thinking about it, I need a relay, with 2 of those "86" positions, that are not interconnected, so the 2 trigger sources never end up being in parallel.

Also, that Reverse switch is the switch at gearbox, it's not an additional switch. I didn't label it right. I'd have the relay at the back of the car, and the reverse wire I'd pickup from loom, on the right, just tap into it, so when it becomes "live" it triggers the relay.

Thanks fellas. Have been going through those threads and some other reading ... It's amazing I work with power every day yet car electrical gives me a headache. lol
I was looking at Darrens drawing, and it is perfect for what I need... however. With that setup, when I manually turn on the light, the reverse lights will turn on too. This is something I want to avoid.
In a nutshell I need a relay that can be triggered from 2 different sources ( reverse light and manual switch), yet not interconnect those 2, if that makes sense ?

If you work it out, let me know. But it's no biggie having the reverse lights come on too. Bit of extra light...

I've modified your drawing, basically I've added a diode between the reverse switch and the relay, this will stop the reverse lights coming on with the manual switch:

You can buy them from Jaycar or eBay them (Cheap cheap):

Thanks bud. Was thinking of a one way valve ( diode), tried to see if there was a workaround first. I'll go with this though. Will report back. Cheers !

OK. Done some wiring tonight. Bought the diodes as flex suggested. But I actually went down the path megatexture suggested. And below is the updated diagram, of how I've done it. The on/off/on switch replaces 2 switches, or a switch and a diode. Flicked up, is normal/usual position while I'm driving for reverse etc.... Flicked down, is when I want the light on without the reverses, camping/work light etc... And the middle turns them both off. I got all the bits, but haven't finished the wiring yet, on paper it should work, but will find out tomorrow when I put it in practice!

That won't work mate. Your diagram is wrong.
Your tail lights are different to the one pictured...
