GC-12 volt outlet in rear quarter panel

Has anyone done the fuse swap with fuses F90 and F91?
Any Gotchas or issues??

This swap sets up the rear quarter panel outlet to be battery-constant rather than controlled through the Ignition Switch.

I am going to do this on my 2015 GC CRD once it arrives.

Thanks

Did it, and no problems at all. Nice for a fridge in the back.

Re: GC-12 volt outlet in rear quarter panel

Would the wireing be suitable for the high draw of a 12 volt fridge
I would doubt it very much

I use mine with a 12v oven - no problems either.

Re: GC-12 volt outlet in rear quarter panel

Great, thanks everyone for your replies.

I will be using it to charge batteries for RC airplanes and drones while at the flying field.
But a small fridge is a good idea as well.
It is a 20 Amp fuse so that's gone to give us about 240 watts of juice.

Cheers

Re: GC-12 volt outlet in rear quarter panel

the biggest let down is the agm battery its not really designed to be ran flat, but what you are wanting to do will be fine.

Re: GC-12 volt outlet in rear quarter panel

I have a 2014 diesel and used to power my ARB fridge using the rear outlet configured to always be hot. When my battery was relatively need that worked just fine however once the battery got to be about 18 months old I ended up needing a jump start on 2 separate occasions and that's with the low voltage cutoff on the fridge set to its most conservative setting. I think the diesels are a lot less forgiving of a low battery than the gas engines. Since then I've installed a second battery hooked up to a Blue Sea Systems LVD (low voltage disconnect) that powers a dedicated 12V outlet installed in the rear compartment on the driver's side. That did the trick.

Re: GC-12 volt outlet in rear quarter panel

Since I can't read the position numbers on the inside of the fuse box lid, would someone please identify the two positions/locations?

Where did you place the 2nd battery? Is it a permanent install or just on occasion? Do you have any pics of your installation?

Look in your Owner's Manual on page 290 or 292 for a fuse layout diagram. For 2013 GCs, it is fuse M7. It can be moved left or right one position. I believe the right position sets it to be always powered.

Permanent. I have an Overland diesel with QL so the space under the drivers seat is out of the question. That basically leaves the spare tire compartment. I molded a form out of 2 part expanded urethane to hold the battery and electronics which is then strapped to the spare tire. Everything is connected with Anderson power connectors for easy removal should I ever actually have to use my spare. Here are a few pictures.
