Rear Power Outlet

Rear Power Outlet / Battery Charger Port:

This is really a simple little project. The 928 has no rear power outlet and sometimes this can be useful for plug in gear (say a powered cooler or a plug-in work light). However I also wanted this to work as a direct plug in battery charger port (only medium current - say ~6A). This way I could quickly plug in a battery charger without having to remove the carpet, cover and spare wheel to get to the battery terminals.

Now in plugging in more than a trickle charger/battery maintainer its a good idea to disconnect the battery too and I allow for that with another related project the Battery Cut-Off Switch which I recommend in combination with this one. One of the biggest challenges here was making the installation look good - the biggest element here is probably just choosing a good looking and functional power outlet. Well you be the judge on my choice - the "Marinco" outlet, with front reinforcing plate and plug in rubber cover. The connection is to the battery via a 10A fuse in the battery box and it is always connected to the battery regardless of the battery switch position.
