If option 1 is nickel plated id take that. Its way less prone to corrosion issues than copper or brass

25sqmm is 4awg Just confirm the 25sqmm. Im abit unsure of that value. sqmm is millimetres squared or mm^2. Its just abit easier to type.

On the negative cable its 25sqmm if i remember correctly

If you are able to make a proper crimp on cable that size do not solder it. On large connections like that that see vibrations the solder forms micro cracks that are terrible for electrical connections. Rather put in some effort to keep moisture out either some form of resin after the crimp has...

Just abit of an update. Ive been running the new fan in the car since ive started this thread and it seems to be performing quite well. I dont have any actual numbers relating to fuel consumption because driving around town i quite like the sounds when i press the loud peddal. But we are going...

If you unplugged the diaphragm valve(its the two pin connector that sits right next to the compressor) or something went wrong with its electrical connection you also wont build any preassure. The compressor will just be pumping back into atmosphere.

Proper crimped cable lug that bolts onto the battery terminal clamp

Okay Yeah i agree that would be best to get that garage to restore the ECU back to original. Then start the car, my guess is majority of those errors will go away, they ones that dont you can then clear. The ones that then return are the errors you have to worry about.

In your first post you mentioned that you bought a replacement ECU. Do you have the cars original ECU fitted or the replacement one? If you have the replacement fitted that should explain all the errors and probably why the immobilizer is not turning off.

https://blackbox-solutions.com/photos/L322lock.pdf Have a look at this too, its seems very similar to the issue you are having.

If the key is not turning at all how are you getting the ignition ON? Without ignition almost none of the modules on CAN will come online. You wont be able to measure a voltage on the CAN bus between CAN low and high on the OBD connector. What you should check is what the resistance is across...

https://www.landyzone.co.uk/land-rover/viscous-fan-speed.349729/ the other thread Slight improvement in cooling ability because of larger fan diameter and better/more effienct fan blade design. Improvement in fuel economy beacause of way more control over what the fan is doing and more...

Some info ive found that might help someone do diagnostics on one of these fans. Pin 1 : Grey : Hall effect sensor 12v+ supply Pin 2 : Green : Hall effect sensor GND Pin 3 : Blue : Hall effect signal out Pin 4 : Black : Fan solenoid GND Pin 5 : White : Fan solenoid 12v+ Pin 1 and 2 is...

So as i said in the other thread im planning on fitting the elctro viscous fan from the L322 4.2 SC into my P38. Its fitted in the car now with permanent wiring to it and the controller still just lying in the passenger footwell. The fan fits into the stock 4.6 cowling with some persausion from...

Okay that makes sense Thanks for the advice ill remember that.🙂

What is GGS and TR? Im from Pretoria. But around the Orange rover mostly will probably be the hottest conditions that the car will see. But i very much want to do a trip up through Namibia, along the Caprivi strip and then back down through Botswana.

Yeah a reasonable portion of why is because i want to. Then next up is the stock fan is 25 years old so i would rather replace it earlier. So then why not just "upgarde" to the L322 fan? I want to stay with more commonly available parts. Itll be alot easier to find a L322 radiator fan if im away...

Yeah looking at @Datatek attitude i can see that. How im planning on having the basics work is a PID algorithm that recieves coolant temp input and outputs a target fan speed in order to mantain the target coolant temp of lets say 95 deg. Then a second PID that receives actual fan speed and...

What is up with your snotty remarks? Where is it not correct?

@Datatek did you bother to read this?
