I chased this light issue for a month. I was able to catch the voltage jump today. You described the symptoms perfect. Thank you for the video it was very helpful.
Thanks for the video! We were able to make it 196,000 miles on our original alternator. Only symptom was the battery light as mentioned. TIP: We just used a 3/8' drive socket tip on a breaker bar on the driver side on the engine front to loosen belt. As you pull bar to passenger side you can reach your hand down (it is snug) and pop the belt off just the alternator.
took the headlight & coolant reservoir out & I had a lot more room. Wobbly socket is needed for that last bolt underneath the alternator. The new alternator didn’t come with a cutout for the positive cable to sit flush so I just bent one end of it while the other end slid right in. Took me about an hour & a half 🙏
@@derekpyper6145 a couple hours? It was harder getting the old one off than the new one on, but not a big deal. Just strange to me at least to replace an alternator from underneath as opposed to from above.
@@derekpyper6145 I did it on my back. It is a challenge. But I had the replacement in hand and another vehicle if I got over my head and needed a break, so I was fortunate. I finally got the old one off and took a breather before attempting the install. Holding it up while starting the first bolt was a challenge, but once I got one started, the other two went right in.
Had a bad alternator. No gauge lights for battery, just a limp mode home and dead battery. Old alt was 0 new alt 14.4. Replaced it. Got a new battery also. Hooked it all up and battery light is on the dash. Drove it for 15 minutes, ran great but had the battery light on. Came home parked it, turned it off, then back on and the thing was dead. 2008 Range Rover sport, 4.4. I’m beside myself. Just paid this thing off! I feel the key to the fix lies in the battery warning all the sudden working. Battery fuse on positive is fine. Can’t think of what would draw a battery to be dead in 15 minutes.
I couldnt rotate the alternator to undo the nut on the main power cable so manage to do it from the top easy enough. Just having a break for 5mins............struggling to wiggle the alternator out. There looks to be less room on our L322 SC than on yours in the video
When I turn my disco 2 on after its already been started and cooled down this high pitched sound just rings out. It stays on for about 2 minutes before shutting off. You can hear it from a crossed a parking lot.
Is there any chance the diode you mentioned early in the video can be corrected, or is the whole alternator trashed once the diode goes out? Just wondering if I'm sending back a "core" that is really a perfectly fine alternator with just a bad diode, and if i can fix that rather than buying a whole new part for one bad component. Thank you.
hi so i changed my alternator recently and the very next day i get code P0563 (system voltage high). Radio stopped working, transmission fault with limited traction and gears. I thought the battery was the issue i changed it and hours later still having the same problem. Please help..
What is the quality of the replacement alternator you are using? If they were rebuilt alternators, a lot of times they will not last very long as rebuild quality is often suspect.
Doug. Fantastic video!! But, I had ZERO luck starting the bolts AFTER installing the main electrical connection. It was not letting >me< line up the alternator to run the bolts. I installed the main after I had all 3 bolts started. This worked for me cuz Doug...I ain't got your skills :)
Absolutely SPOT ON! Finally installed an alternator yesterday after watching this and I am NOT a mechanic. Flawless. Great video. Thanks!!!
What engine size was your range rover?
I don’t even own a Rover but I accidentally tapped the vid and found it interesting. Thanks for a quality video.

I used a breaker bar with a 3/8 adapter to loosen the belt. No need for special tool on 08 lr3

210,000 miles and just over 14yrs from this alternator on my daughter’s 2008 rrs. Often times you get what you pay for. 👍
How long did it take?

@@tmcorey1 yeah, I'm no mechanic but seems straightforward. I just don't have a way to lift the damn thing.
@@tmcorey1 and it seems like doing this laying on my back from underneath would be quite the challenge. lol.

A really clear and easy to follow video, thanks for uploading!
This as been a life saver!! No lie love this channel. I have and 2007 Range Rover sport supercharged.
Excellent presentation love it

I had to put mine in off road to get to it. It wasn’t that hard of job. Just follow steps and take your time
Any videos on a Starter replacement and the Starter relay location?
So to free up the tensioner you just put a 3/8" ratchet square in the top hole of the tensioner and lever it round?
My battery light comes on the dash, I have changed my Autanator it still comes on and charging half

Do you have a video of alternator replacement on a 2018 RR Sport?

Hi Matthew, once the diode pack goes the alternator is pretty well cooked.

Hi, have you got a video on replacing a ACE pump
Is the process the same if my Range Rover is non supercharged?
265,xxx Miles.... Thanks for the Video
Please help replaced my alternator two times but both overcharging! To 18v wht can it be
Hi guys spot on video, I'm going to put an alternator on my car this wknd, would this be the same for a 09 3.6 tdv8 sport
Thanks
How did it go? I have a 3.6 tdv8 aswel and im thinking to do the same
Would this be the same on a RRS 3.6TDV8? abiut to do mine today
Didn’t work for me, the cast housing where the 3/8 drive was supposed to “fit” just blew out all the soft cast metal. Useless now probably
I’ve replaced my alternator 3 times on my 06 super charged 4.2.
My question is why does it keep failing?
Any thoughts?

Pliers and air tools... 😐
