Nissan Patrol 4x4 (Africa)

Melcom is a free country use it dont use it have alook after 30min when your crank battery is full your voltage drop down sometimes as low as 13.8 .
Goolgle ideal charge voltage of a lead cristal 14.8 or more .
Crank batteries break after 14.4 v but voltage regular drops down as amps is put back .
Ave smart battery can take 20% of amp hours at ideal charge voltage .
Anyway if it works for you keep the solenoid system . We do big solar systems ect and have been testing it for years to see what works and what doesn't.
When piet got married at Kubu had to con 4 systems to charge by forcing them to stay in .
The batteries has evolve a lot .there is a reason why NL made a dc to dc system ....its the way forward.
With your system of 2 batteries you might want to look at a smart pass to get more amps when needed .
You are welcome to bring your car around i will gladly help you measure ect .

Thanks gentlemen, I seem to have the correct layout with regards to where the fuses are installed. And thanks to you guys I am a little bit more calm regarding the fuses I have in-line. I just want to mention that what Tinus said regarding the LED light wires that melt but the fuse doesn't pop was similar to what happened to my friend - the fuse never popped.

I will try and source a glass tube fuse tray - I always just assumed they were to fragile for corrugated roads.

With regards to the types of charging from the crank battery - that is a whole different kettle of fish. I will reserve my 2c when that thread pops up.

It's information like this (fuse setup) that keeps families safe and camping gear used

Look on 4x4 direct website they do very nice inline stuff . The biggest problems come in when people put in charging systems ...the other day a guy nearly burnt his car down becouse he had a NL duel battery monitor installed the wires 1mm wires was on a 80a fuse from each battery ....it rubbed though just were it comes via the fire wall ....lots of fire ect ....be carefull everytime wire size change put the correct fuse
