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 🙏
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.
@@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
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.
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.
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 :)
