I read up about alternatives and came across this little gem at 4x4Direct.co.za. The HcdP Solid State switch for double battery system. I looked around on the internet but couldnt find people who reported on them. Matbe I just looked in the wrong places.

Anyway, last week Thursday I went to the 4x4Direct shop down the road and got one. R961 later I walked out smiling like a boy with a new toy.
Why did I decide on this particular setup?
1) It is Solid State. Meaning no moving parts. Unlike the National Luna Solenoid system, which relies on moving parts to do the switching. No wear & tear.
2) It costs about half of what a new NL Solenoid system would have cost.
3) It is half the size of a NL Solenoid system
4) It is easy peasy to wire.
5) It is waterproof, and can be mounted in the engine bay, not finicky about heat.
