Hi,
The Owners Manual claims that the Dealer can alter the wiring somehow to make the Rear power outlet run on Battery voltage continuously rather than being controlled by the Key.

Does anyone know what the actual modification is? I want mine to run continuously regardless if the Key is on or not.

Thanks

I found the solution. Fuses F90 and F91 are switchable for Battery or constant power. See page 157 in the Owner's Manual.
Cheers.

Never seen an owners manual. How do you get that ??

GC manuals ( and many others ) can be found at:

Just go there and look for the downloads and then select your Year and Model; presto!
Good Luck

See my post for "Battery Failure" in this forum. If you're going to do this, keep an eye on battery condition. I had another problem (AC Clutch switch) at the same time that contributed to my battery failure, but the dealer tried to blame it all on me. However, who knows if switching fuses may have also caused the AC clutch switch to fail.

RichH,
Thanks for the heads-up. I will be really careful in the fuse swap; the picture in the Manual shows it clearly.

My current V8 GC has a constant voltage rear outlet and I could not live without it. ( use it to charge Radio controlled airplane batteries ).
The swap will be on my new Diesel GC that is about 5 weeks away, I hope!

Let me know how that goes. I'm wanting to use that again for my emergency strobe lights, but I'm a little gun shy. I think the real problem I had with the battery going dead was the stuck AC clutch switch, but it happened just after I had moved the fuse. Then the dealer overcharged the battery and it leaked acid into the battery box under the passenger seat.

They made good on it, including providing a new battery, but I'm leary about electronic stuff.

Hey Jim....when you say switchable for battery or constant power... Which fuse do you change with to make it constant?
F90-91 switch with F104?
