SAM Fuse Holder
When using the auxiliary fuses 36 to 44 ideally you need to use a fuse holder.
Thanks to forum member Paul.art for sending me this fuse holder. Extra Fuses The SAM unit has nine extra fuse places down the side, smart obviously put them there for
their own usage but as most cars rarely use more than two of them, let's take advantage.
What Amperage Are They? That's the best bit, it is what ever you want it to be. Any standard size automotive
fuse will fit into the holders which are then clipped into the SAM unit. What Control Do I Have? You have two options for the power to the fuse: Constant Live Switched Live
The constant live is always on and the switched live comes
on when the ignition key is turned to position 1.
How Do I Select It?
The four fuse spaces nearest to you are switched live.
The five fuse spaces furthest from you are permanently live.
The Fuse Holders
The fuse holders used to come in two colours:
Orange for constant live applications Black for switched live applications
The orange ones will only fit in the constant live locations and vice versa.
The only difference apart from the colour is the location of a small plastic
tab to stop it sliding in the wrong position on the SAM unit.
Over time, however, the colours of the fuse holders have increased.
Here we can see the holder with a fuse removed.
The fuse pushes into the holder where it is held in with a clip.
The clip can then be inserted into the SAM unit after being wired up.
These can be bought directly from smart.
The part numbers are:
Brown - 211 545 09 01
Orange - 211 545 12 01
Black fuse holder - 211 545 05 01
Apparently superseded by 004 545 57 01 (thanks Francesco)
Clip in terminal - 011 545 84 26 Clip in terminal - 004 545 52 26 (thanks Jonathan)
The terminals are the clip in metal connections that fit inside the fuse holders.
Both of the terminal part numbers should get the same product, they could just be regional codes.
Buying These Items
They originally retailed for about £11 each but they have come down to £1.50
Remember that you need to purchase the terminal as well which is about 70p.
These can be bought directly from Smart.
Adapting Permanent To Live (And Vice Versa)
What happens if (like had happened to me) you buy permanent live but need
switched live fuse holders? Or needed permanent but needed switched?
A switched live fuse holder will not push into a permanent fuse slot and the same
goes for the other way around. Not to worry though as it's very simple to modify.
Here is a permanent fuse holder, note the small line of plastic down the inside.
Use a knife/file/sandpaper/your teeth to remove the tab as shown below.
Permanent live fuse holders have the tab nearer the middle, switched are near the edge.
With that plastic tab taken out the fuse holder will fit in all locations and work fine.
In fact, I found the adapted ones to be more secure.
Constructing A Fuse Holder
Get a suitable gauge wire, strip back about 6mm and push it into the crimp.
I have never liked crimping stuff as you never get a really good join unless you use the
right equipment. As they cost a lot of money and no one will have one, it's easier to solder.
Flux the bare wire end and the contact and apply heat and solder until it runs around the wire.
Allow to cool before sliding it into the back of the fuse holder until you hear a click.
Push the locking tab in place to double lock the contact in position.
Insert the fuse of the rating you require.
You are ready to join it to what ever you are powering and plug it into the SAM.
Remember that these will output 12 volts so check what you are powering.
