  1. Sigi_H, I envy your arduino prowess!  I’m just about completing a full rewire of my 1991 110CSW, without an arduino, but following many of your philosophies.  I’v got twin batteries, one dedicated solely to the starter, and all other loads supported by the other one.  In an attempt to minimise switch burn out every circuit that draws more than 4 amps I’ve routed through a fused relay, which means quite a lot of relays when I’ve added driving, front fog lights and work lights all around, plus various 20 amp utility outlets.  I’ve also included a dedicated earth from each consumer going back to an earth busbar.  I have five of these in total, all going back to the battery negatives.  I’m trying to avoid poor earth connections that rely on earthing through body work of chassis connections which always seem to be plagued with rust induced poor connectivity.

    I’ve also added front and rear Anderson sockets, fed through lengths of welding cable, to enable connecting jump leads to another vehicle.  These also come from and return to the accessory battery, not the starter battery.

    Your proposed use of an arduino and associated bus sounds very good and should simplify the cabling tremendously.  I wish I had the knowledge and skill sets necessary.  I’d still recommend fuses in the power supply to each user since these will still be carrying currents able to generate major problems (short circuit fires!).

    I had to repair a crumbled section of my front headlining as leaks over time had weakened it too much. I used hardboard and fibreglass and was very happy with it.

    You could put a backing piece behind the hole, and build it up with resin/matting.

    As above.  I’m using fibre glass matting in places on the back of my headlining panels to stiffen them, particularly at the edges.

    It's a shame you're over there or I'd send you my unit. My new one has arrived and suits my needs so now I have one surplus. 

    I suspect the postage is more than the unit cost, which would wipe out the benefit?

    Many thanks for the thought, but you are right, postage and import duties would far outweigh the purchase cost of a similar unit over here.  Glad that you’ve got a suitable unit and I look forward to you posting details.

    Well......I'm not so sure, but it is entirely functional.ScreenBadTime.jpg.5d1fcefb8339aa088745d7b76de12ff2.jpg

    I think you have two options for the nav, either to use the carplay/android functionality or just 'dumb' screen mirroring stuff. I'll have another play with it later as I haven't driven far enough to need the nav. I've just used it for the rear view camera and music so far, which it's done very well.

    You do need to be careful with some of these units, this is the second type I went for. The first wanted me to download an app that would have 1000% told The Party what brand of socks I wear. That only really becomes an issue for the more advanced integration and the new one doesn't seem to want to do any of that. The first one was a better looking solution but was exactly 1mm too large to fit in the fascia with the centre removed and in fairness was good in every other way.

    In the interests of transparency, I was inspired to find a larger/better looking screen after my post yesterday. Having had two units that both worked acceptably well, I took the risk on this one. It was available for £55 if you look carefully on the listing (all legit through ebay).

    A bigger screen is better for the cameras and more visible at a glance, and I have the space around the fascia to use. I think the connectors look a bit suspect so if it's not a straight swap or works any way differently, it'll just go back.

    Sorry Naks, complete derail to your thread.

    Yes, that looks good.  Could you provide a purchase link, please?

  5. I’ve removed my crankshaft mounted fan, and I’ve got my two previous A/C condenser fans re-allocated to cooling duty.  One fan is dedicated to the intercooler (300Tdi), ducted separately, and runs full time when the ignition is on.  This helps when speed is slow but the engine might be working hard.  The other fan is on a 2-stage thermostat and starts when the radiator feed exceeds 82 Deg F.  As coolant temperature rises there is a large diameter electric fan, using the original ducting, that kicks in 88 Deg F.  This also initiates a buzzer and dash warning light to warn that the coolant temperature is rising.  I’ve also got a low coolant level detector in the header tank which is also connected to a warning bulb and the buzzer.  I’m intending to get a coolant temperature indicator which shows actual temperature in degrees to replace the standard LR temperature indicator.

    …….. Going by the wheels and the suspension mounts, I guess Land Rover. The cross member seems well modified to hide what it is.

    I don't understand how you can make that assessment.  Can you please help me.  It appears that there are only two photos and I can’t see any of the suspension.  Yes, I can see that the wheels have 5 studs, but where can you see suspension mounts and the cross member?  I’m not trying to be a smart-ass, but please tell me what I’m missing.

  7. A good suggestion, thank you, fmmv.  I’ve already designed the circuit and I’ve identified that there are two pairs of contacts that make contact when the switch is ON, and no contacts when the switch is OFF.  This means that I can use it as a double throw switch with one pair connecting the battery  positive supply to the flasher unit and the other pair supplying the flasher output to the four sets of indicators.  All I need is four diodes, which I have.  I’ll let you know when it’s all working.

    Shipping cost is a killer when things get heavy 😢 

    When I worked in Kuwait, where I bought my 110, I bought a whole pile of bits that were quite heavy, probably about 100kg, and had them shipped out on a pallet by sea.  It was reasonably cheap as I remember.  This might be an option if you are not in a hurry.

  9. My indicators are all working correctly but there's nothing when I switch the hazard switch on.  I have confirmed wiring continuity on all wires in the system.    I suspected that I have a faulty hazard switch.  With the switch removed, using my multi-test meter to identify internal connections between the switch pins I got the following results.

    Switch in OFF position:  no internal contact between any two pins.

    Switch in ON position:   the only internal contact was between pins 5 and 6.

    Looking at the back of the switch:          image.png.2da4f80e7db605f4137314c393fcf8a9.png

     

    I bought a new switch.  It came in a blue bag😞!  It has exactly the same contact pattern as my old switch.

    So:

    a)  is my original switch, and the new one, faulty?  

    b)  If it is faulty, what internal pin connections should there be in both the ON and OFF positions?

    c)  If the switch is not faulty where do I go from here?

    Many thanks for any info and suggestions that I receive.

    …. using a puller means the liner will get warm and be really tight , because it take’s some time to set this up .

    as mentioned above , use a heatgun to heat the block a bit .

    If you can partly assemble it and then get a plastic bag of cardice into the cylinder that should help to keep it colder.  Any condensation can be removed later by WD40, brake cleaner or acetone.

    I’m not wishing to hijack this thread, but I’ve not come across isolators mentioned in the Defender sub-forum previously.  From the above it appears that they can be fitted to standard Defenders, but are they effective in reducing noise transmitted into the cabin?

    Mike

    Many thanks for the contrasting opinions.🤔  I don’t think I’ll be investing, but I could change my mind!
