ive had this problem before,i found out in the end the wiring loom had corroded behind the lower drivers side kick panel and under drivers sill trim,chopped it all back to under dash and soldered in a new piece of loom with good plugs back to becm,sorted no more problems
just plugged in the voltmeter and it reads 13.9v turned everything electric on i could find and it stays at 13.9v. but now i have no Dash power at all and the HEVAC is working again. Range Rovers are a confusing species...
Do I win a prize for (again) correctly diagnosing something??I would suspect a dodgy earth causing a leakage somewhere....
Check the under seat fusbox for security too, as the flashing panel lights are fed from Fuse 1 and the interior lights (which some dash illumination lights and the HEVAC lights use) is Fuse 15(?)...check these for security....
i think the rf receiver has already been snipped as it doesn't work. was going to think about re-connecting it but if its an existing problem i'll leave it.
i'll go and do tests on the alt and more on the battery as they are both new so i'm thinking that its got an under powered battery on it. what's the best battery to have on a RR? i think mine is type 072 70AH 600A
