There are at least SIX different fuse types can be used in the IEOS Grenadier, being:
@bnebenda has compiled a list of the all the Grenadier fuses into an Excel Spreadsheet. It can be downloaded here.
MINI BLADE FUSES
The main blade fuse used is a Mini fuse, not a low-profile Mini fuse or a Micro2 fuse.
Mini fuses are 10.9mm across, 16.3mm high and the blade width is 2.8mm.
The fuse box diagrams tell what amp ratings are required.
JCASES FUSES (BOTH TYPES)
The Interior Fuse Box (Fuse Box 1) uses Low Profile JCase Fuses (895/PAL Fuses). The Cockpit fuse box (Fuse Box 2) and under the Bonnet/Hood fuse boxe 8Fuse Box 3) use the Long Profile JCase Fuses (495/PAL Fuses), NOT Low Profile JCase fuses.
The various fuse box diagrams tell what amp ratings are required.
These fuses are made by Littelfuse and look like a miniature Otto bin or Wheelie rubbish bin.
Warning: the INEOS Grenadier does not appear to use MCase fuses, either slotted or unslotted.
LITTELFUSE FHZ BUSBARS IN THE GRENADIER
The 7 Stud Busbar and the 5 Stud Busbar used in the Grenadier have fuses – ZCASE® MEGA Fuses and SHUNTS. This thread here looks at the busbars in detail. For present purposes here is a summary: the known ZCASE® MEGA ratings include: 80amps, 100 amps, 125 amps, 150 amps, 300 amps, 350 amps and 3 SHUNTS.
ZCASE® MEGA FUSES - SPARES
Because the busbars are sources of power for fuse boxes, owners should give thought to having spare ZCASE® MEGA fuses, perhaps 80 amp, 100 amp, 125 amp and 150 amps, plus a spare SHUNT.
However, ZCASE® MEGA fuses are expensive to buy. If you only travel locally or regionally you may not need any spare fuses. For remote travelers you have little choice but to buy some spares, as the ZCASE® MEGA fuses are hard to source anywhere in Australia. Experience has shown the other fuse types in the Grenadier are also hard to source regionally or remotely. For me, spare fuses are a must have for remote travel. Ultimately each owner needs to decide what best suits their own needs, I hope this post helps with that decision.
MIDI FUSE
A single 60 amp Midi fuse is used in the fuse box under the hood/bonnet (Fuse Box 3).
MEGA FUSE (MIDI STYLE)
A MEGA fuse in the Midi style are used to fuse the CTEK120S and Fuse Box 6. The CTECK120S is fused using a 300 amp MEGA fuse. Fuse Box 6 located under the bonnet, uses two MEGA fuses (Midi style) rated at 125 amps. Fuse Box 6 uses two 125 MEGA fuses (Midi style). Look here. Thanks to @bnbenda
All owners take note: The ZCASE® MEGA fuse and MEGA fuse (Midi style) are must have fuses, because they are used to fuse the CTEK 120S and this is where some the high amp devices are fused, from 80 amps to 350 amps fuses (both the 5 stud and the 7 stud busbars are rated up to 400 amps).
RELAYS
It has been suggested to me the Relays in the Grenadier are Bosch Relays. This is only a DRAFT Table, everything needs to be confirmed:
Fuse puller needed
It is really hard to remove the small blade fuses and the JCase Fuses with your fingers. You will need a fuse puller, long nose pliers or something similar.
You just remove the nut from any stud in the busbar and lift the fuse out and replace the ZCASE® MEGA fuse, of the same rating.
There will be variations between models
The fuses in use will vary between IG models, depending on what accessories you selected. Treat this as a general guide and remember to check each fuse box in your car before starting to work out what your spare fuse kit needs. When in doubt speak to your dealer or auto electrician.
Australian source of fuses
In Australia all these fuses can be purchased from the retail arm of Prolec called Swe-Check. The online shop is here.
MEGA range ZCASE® fuses are expensive. Looking at the Swe-Check website they are between AUD25 and 30 dollars each, depending on the rating. Hopefully that will rarely blow.
JCases fuses are around AUD4 to 5 dollars each, at the time of posting.
All the fuses are made by Littelfuse.
UK source of fuses
@Tinki posted he could buy most of the needed fuses from the Mouser UK website.
SUGGESTED SPARE FUSE KITS
My suggested spares kit is listed here. If in doubt speak to your dealer, mechanic or auto electrician.
- Mini blade fuse (not a low-profile Mini fuse or a Micro2 fuse);
- JCase Low Profile fuse (895/PAL);
- JCase Long Profile fuse (495/PAL) - also called just a JCase fuse;
- ZCASE® MEGA fuse (and SHUNTS);
- Midi fuse; and
- MEGA Fuse (Midi style).
