Any photos?

That's good work @uytter . Well done. This is all from your photos so I'm not 100% on any of this advice but..... The valve looks like an on-off switch. An electrical isolation valve, if you wish. Keep the positive terminal of the battery set isolated, don't attach the positive cable for...

I share your struggle. Mine looks similar, but sufficiently different so that the standard rattle cans don't match. I'm sending a sample to paint man, asking for a match

Good, batteries wired correctly. Now, your machine doesn't have standard Landrover wiring, it has lots of continental fuses, and this I can only assume lots of split out circuits on top of the Landrover loom. However there is most likely to be two main paths into the circuits. 1) permanent...

That's a really smart idea. Well done. Thank you, also, for letting us know.

Simple things first. Disconnect the batteries, leaving only the cable between them. What voltage do you get across the two batteries?

I am facing this job. What modifications did you make?

Get a multi meter. Then you can start looking for the problems. First. You do have 2 batteries, right?

Welcome!

Any photos of what you got?

Get it reconditioned? Got any photos?

Confused. Oil filter casing was blue. Air filter, oil bath type, was black.

Series rad in the standard place. Spal fan and flat shroud between rad and engine. Similar to this, with some minor trimming. Intercooler in front of the rad with some not great brackets holding it. Both cooler hoses under the expansion bottle. Oil cooler in front of the intercooler. It all...

Mine is a disco timing chest, defender manifolds, Skoda fabia RS intercooler, mocol oil cooler, battery over the relay, shuffled forward. Turner head and diesel Bob high power IP. I really like it. Got some upgrades coming, though.

Did you remove the bypass thermostat thingy in the oil filter block when you blanked off the cooler?

To get DVLA information register as a car park owner. You'll get details no bother.

Gauges are unreliable in accuracy, but good for a trend. If the lower hose is cold then it's probably okay, assuming the thermostat opens. The voltage regulator in the dash needs an earth and is essential for gauge operation.

Donno. Got a parts manual? Google the part number and you'll get the thread and dimensions.
