Hi Tomdoc,
Have you finalised a full set of spare fuses yet so I can order a full set?
Appreciate any help,
Scotsitalian

 

[TheDocAUS]

Morning,
Have you finalised a detailed list of all the fuses so I can order a full set of spare fuses?
Appreciate any help,
Scotsitalian

As each car's fuse requirements vary slightly based on the accessories selected. Look at the draft fuse list here, then add/subtract fuses based on what you need for your car. Then buy your spares.

 

[Scotsitalian]

Thanks for this list.
I’ve got an oddball spec, I cancelled my 5-door station wagon order and IS came back and offered me a Fieldmaster with front winch, auxiliary wiring loom but no auxiliary battery so I’m in process of fitting one with the Ctek 120S , brackets and 105aH aux battery.
The 300 amp inline fuse, z case fuse etc is coming from Littelfuse thro the uk guys and cable etc from Switch so pretty much duplicate of the factory setup, mine has the second 5 fuse Busbar but have not checked to see if the 300amp fuse is fitted!

 

[TheDocAUS]

Then your setup is close to my car, upon which the spares list is based.

do we really know what are the INT 1 and INT 2 Auxiliary connections rated for? i was trying to run a smart BlackVue battery to run my single camera 12 volts, and it's ridiculous the voltage im getting from INT2. it barely keep the battery charged. camera dying all the time. and receiving a low voltage warning message in the battery app. something is not right. are those INT 1 and 2 actually 6 or 9 volts only?

Something amiss with your setup. I get full battery voltage on both INT 1 & INT 2 with them switched on.

Alex3world check for a loose wire and also check the grounding.

If you have a multimeter check the voltage on the circuit when live. I know you mention 6 or 9 volts is that a multimeter reading?

Agree doesn’t look right. The first photo you showed looks like 0.9v DC power in (ie off) while your unit is still drawing power. No wonder you are going flat.

Hi all - still learning the most effective way to navigate and use the forum and community here. Posted in a separate, stand alone thread on a problem I ran into on the truck last night.

Working on the truck last night and ran a tool off the onboard inverter - an oscillating multi-tool. But afterwards devices on the INT 1 circuit aren’t coming on (USB charger plug, wolfbox). The switch in the console lights up, but nothing comes on.

I checked the FI29 fuse - looks good. Is there something else that could have tripped or blown? A fuse? A relay? I’m a bit over my head - which is great, that’s how you learn - but a tiny bit lost today!

If all else fails, I’ll go buy some 10A replacement fuses tomorrow in case the fuse isn’t actually as good as it looks. But would love any other ideas of things to poke and prod!

The inverter is only good for 400w. I suspect the oscillating tool pulled in excess of that and blew a fuse as you suggest. Is FI29 the specific fuse for the inverter? I have not checked Roc Dr.'s supplemental manual to confirm.

 

[BartHarleyJarvis]

FI29 is the fuse for the INT 1 LHS footwell.

I searched through Rok Dr’s manual and the owners manual and I couldn’t easily identify the fuse for the inverter. But that was Ctrl-F, Inverter.

 

[BartHarleyJarvis]

Wait - Inverter fuse is a red herring - I just plugged a light into the inverter plug - all good. So just INT 1 not working.

Dig into the fuse appendix 2. The inverter fuse is a 60 amp jcase battery fuse in the 7 stud interior pre fuse box

yeap, im going to use rather the 12volts rear cigarette lighter fuse in the co-pit and let the aux 2 alone. sometimes it gives me 12 volts other doesn't.

 

[alex3dworld]

its the reading in the app connected via bluethoot with the blackvue smart battery.

BARE WIRE ENDS - draft Table - updated Table below
I complied a Table for all the bare wire ends in the Grenadier and QM. First draft attached. I still need to re-check all the information. Terminology is consistent with the Rok Dr Guide. If you see a mistake or have a suggestion, please post it.

I still need to find the ignition source for US models in the last row. It is posted somewhere here. I also need to confirm sentence in yellow highlight.

EDIT: TABLE REMOVED, UPDATED TABLE BELOW.

 

[TheDocAUS]

I have the 4 wires on US models identified thanks to @anand. Look here.

Revised table attached. Still draft as a few more checks need to be done. EDIT: an update is required to the last row concerning the number of wire ends.

EDIT: TABLE REMOVED, UPDATED TABLE BELOW.

 

[TheDocAUS]

Third version of the Wire ends Table below. Items in yellow highlight are being worked on/rechecked. It seems from the 2024 model all cars have 4 wire ends (if you choose the High Load Aux Power option). Thanks @Rok_Dr

All the FI numbered fuses have been checked against a 2024 Model User's Manual and 2023 Manual. The FL03 fuse is from work done by forum members on the aux power fuse box, in this thread.

EDIT: TABLE REMOVED, UPDATED TABLE BELOW.

 

[Rok_Dr]

A correction.

Logically the 4 wire outlets have be present on all MY24 vehicles if the tow hitch/electrics option is selected.

For MY23 vehicles the 3 wire outlet was part of the high load aux option as it was for a compressor option that INEOS contempated at the time.

Happy to be proven wrong

Cheers
Steve

I just used the wording in the 2024 INEOS User's Manual. You might be right.

So you are saying that these 4 wires now only come with that option selected (hitch option), you no longer get the 4 wires with the the high load aux power option? I might ask the dealer.
