2007 Defender 90 Puma 2.4 CSW Indus Silver

Under drivers seat fuse box

Hi Guys, i have a bit of a mystery on my hands which is making me scratch me head a Tad.

I had a problem with the glow plug supply recently which B4lamb helped with curing, (Many thanks for the help it was very appreciated ) while in the fuse compartment under the driver seat checking all connections and relays making sure the screw down fuses were not blown I found a seperate blade fuse holder with two fuses, one has a 60 amp blade fuse the other a 30 amp fuse, when checking the 30 amp fuse I discovered it had blown!

The odd thing is everthing works that I can see, when checking with my multimeter one side of the 30amp blade is live as you would expect, inserting or leaving the 30 amp fuse out makes no diffence to any of the items needing power?

My question is to the forum and hopefully somebody that has an in depth knowledge of the Puma wiring system such as an auto electrician, can they advise what the 30 amp blade fuse serves? also some indication possibly what the 60 amp blade fuse powers up? I cannot find any reference to these two blade fuses anywhere!

Regards to all

Ah the 60amp stupid me is the glow plug relay, I had a moment of forgetfulness, the 30amp is the mystery?

Hi Dorset, the 60 amp fuse im advised is the glow plug protection fuse as the voltage there is identical to that of the GP rail voltage.

Hi Dorset, sorry for the delay in thanking you for the circuit drawings, unfortunately after studying both the drawings neither show the 60 amp or 30 amp fuses in question, however the drawings will be helpful for other things.

Many thanks

Hi Dorset, thank you for your reply, at some point the previous owner or their mechanic has run riot in the under seat fuse and relay location as the glow plug relay was not connected!! Plus none of the relays were on their rail locations, its still the same as none of the relays will fit over the posts they are meant to be on which im going to sort out soon.

Will take a pic of the two fuses which are located in joint holders when I get home and you can then see for yourself the positions referred to plus the pickle the previous owners left the fuse location in with all the relays cable tied together in a bunch.

Cheers

This is what my 2007 2.4 looks like. Just the 15a floating fuse holder feeding the ECM.
Do you have any photos of yours? Does it look factory? Are the wires taped up/bundled in with the factory loom or do they look aftermarket?

The 60A is glow plug fuse, pre-relay. C0621 is the holder number, neither the fuse itself nor the input wire are shown on the wiring diagrams, just the wire out from the fuse (C0621-2) going to the glow relay C0215-1.

The 30A is for the starter, pre-relay. C1217 is the holder number, again not shown on the diagram. This time is it supposed to be shown in the feed into the starter relay C0151-30. The brown/white [NW] wire doesn't actually go all the way to the relay as shown, it actually goes to this fuse holder. Then there is a brown/grey [NS] 4.0 CSA wire from the fuse to relay terminal C0151-30.

That's a link to a diagram that I produce and posted on this forum! I'm glad it's been useful, which it must be if it is now circulating on the web or in the cloud or whatever! Does it make me an Internet Legend?
