12V accessory socket wiring
« on: May 02, 2021, 12:52:34 PM »
The always-on 12V feed to the accessory socket in my LH pie warmer has died.  The accessory socket itself died some time ago and was replaced with a dual USB outlet, but that's not relevant.  An inline fuse has been fitted immediately before the socket (it looks non-OEM), and that fuse is blown.  But the upstream side of this fuse is not reading 12V so I'm figuring there is another fuse upstream from this. Blowed if I can find it though. I've checked the fuses in the fusebox under the left side cover and they all seem OK.

Anyone got any ideas about where I might the fuse for the accessory socket?

It may be down by the battery, its not a standard fit.

Thanks Brock.  Are you saying that the 12v outlet in the pie-warmer is non-standard?  That would explain why why I can't find the fuse in a 'normal' place.  I'll go hunting.

I had assumed that the outlet was OEM because the wiring that leads to it seems to disappear into a loom.  Maybe it's OEM only on a Police version?

Actually, with a bit more poking I found that the +12 to the socket is fine. The fault is a high-resistance earth return. If I connect the -ve side of the accessory socket to another earth point it works fine.  This might explain why it's been 'iffy' for a while.

The 12V socket, isnt a standard fit. It may have been added in the police workshop to allow for use of a radar gun..

Yeah, makes sense.  But whoever added it did a shocking job of wiring it in. The joints are wrapped in electrical tape which has gone all gooey. The intermittent ground return goes down deep where I can't get at it without removing more plastic than I'm up for.  At this point I'll chicken out and get it fixed at the next service. At least I'll be able to point the workshop to the shoddy bit.

Thanks for your help Brock.

If the wiring is shoddy, then not done by PoPo workshop, probably the next owner.

My wiring is all connected by crimps, and heat shrink. No tape used. I hate cutting into existing wiring, bound to create problems later.
