pays to check where crimp lugs attach to cable as well as where the lug contacts the body ( usually large deposits of green sulphate is a good warning sign of future problems)

Fitting a hidden but accessible manual isolator is one thing, but an automatic isolator on a car that relies on electronics?

Have the relevant bracket been fitted

the problem with led units that are fitted in original lamp holder that rely on the bayonets for connection is that the current drawn is so small that when the contact point oxidise and the led then is unable to draw current through the oxidised...

the cable is the AERIAL

3BA on sender then 6-40

and those two sized screws were ? for the benefit of others

have you checked the ignition switch feed voltage to eliminate the switch it's self

for the R.R 14cux but may help

Jeez, who bloody designs this crap🤯 Certainly those who don't work on them... But then, once it's out of guarantee..... who cares😵‍💫

TV's Mythbusters proved it is possible to polish a turd, but a turd is still a turd even if there is a shine on the outside. Checking and sorting any issues with chassis, bulkhead and running gear is what should come first.

take a look

try

any images of the battery connections main earth cable and the starter motor and alternator connections .have you checked the output voltage on the alternator main connection and then on the starter motor main connection and then the battery

AERIAL

on the rebuild was a discovery harness used for the engine connections utilizing the bulkhead plug etc and spliced into the original body harness or the whole vehicle TD5 harness used

have you adjusted the lumbar position to support your back

what year and when was the engine fitted as you say it's a 110 and not a td5 defender as this affects the wiring

worth a read

before condemning the battery and alternator as steve2286 said DVM. you could have loose or broken wire's to the alternator loose or badly corrode battery connector's ,badly corroded earth connection so look for corrosion on the cable crimps...

may help

If you are interested, I can go and measure the dimensions (although mine is a 2001 FL1 Td4, not a facelift so maybe the centre console etc is not the same, so dimensions you would need wouldn’t be exactly same?) Not rocket science tho.

is there not provision for front fog light that you can use behind the front bumper without baster sizing the console

a roof rack with a sheet of OSB will give you more room

if its a series 1 or 2 the original pin were 3BA ,was the old tank re-tapped at some time or ask the new tank supplier what thread size he used

as Datatek mentioned

when applied to plastic and rubber trim returns them to black ,require rubbing in an excess buffed off

have you tried try boiled linseed oil works great on the Freelander plastics
