Got the Battery not charging error and tested battery. Not only was battery dead, but was the wrong size (physically). It was an AC Delco battery so I replaced. Tested voltage and alternator was not sending voltage so I decided to remove and get tested. Looks like alternator is original Jaguar branded Denso. Test machine revealed short and failure.

So I am now wondering if an aftermarket alternator or an OEM unit should be used as replacement. I am 1/2 way thru the R&R job and it is a pretty big one, so I do not want to do it again. I'll post my procedure with pictures when I'm done, but wanted to get some feedback on the acceptability of using OEM vs other parts. I know this is not a show car and it's production numbers make is semi-rare. Just want to make sure car is set up for future value/interest appropriately. Thoughts?

 

OEM alternator is expensive!



You can save a lot of $$$ by having your alternator rebuilt by a competent shop. Google "alternator repair shops near me", read their reviews, and call them.

 

Ok, I understand that many on this forum are not really DIY'ers and rely heavily of the dealer networks fro their parts and service. This is not a knock, just an observation from someone who is a member of many automotive forums. It also seems to be the easiest and most convenient practice, thus most expensive. I tend to go to the dealer only when it is required (part availability, specialized test equipment, manufacturer recalls, etc)

While I will not rule out OEM part, rebuilding the current or sourcing from other outlets (I'll bet I can beat that price by a mile) the question really is... will installing a aftermarket vs OEM unit have any adverse effects on the practice and value in preserving this type of car. Was kinda hoping that could be the discussion.

Compare your alternator to the 7 photos on Amazon. If it's identical, then that's what I'd buy.

P.S. Don't forget to carefully remove the Jaguar sticker from your OEM alternator and attach it to the new, rebuilt alternator.

 

The simple answer is yes, aftermarket parts will adversely affect the value.

 

If you’re worried about collector value with a correct alternator, you better have under 30k miles forever, and never do anything that isn’t correct. These cars are not rare enough for that to matter much.

Even so, paying a shop to rebuild it will keep it full original Jaguar in terms of originality that the case and any serialized parts is the one fitted originally.

I’d rebuild the stock alternator, it’s cheaper and it’ll work great. That’s regardless of that it’ll keep the car more original.

 

Btw, the shop near me does alternator rebuilds for 65-85$ and it will be what you brought in. So it’ll go back in just right.

 

So I'm thinking folks would want to see a Denso unit. My guess is that purists would actually want to see that. There are plenty of reputable manufacturers that appear to make a replacement for this (Bosch, AC Delco, etc). Then there are the store brands (Duralast and the like). I know it might be more subjective, but if you were looking for work/parts that would have been done on the car what would be the OEM, Major Brand, Gypsy parts value effect. Probably looking for more cultural value. ie. I saw that my battery was an AC Delco unit. I did not know that when I bought the car, besides that fact that is was physically 1.5 inches shorter in length. I was happy it was not an unknown brand. Pretty much figured a battery would be a maintenance item and would not be original. So, if you pulled off the belly pan and saw a Denso alternator; AC Delco brand or no name brand how would you react or what effect would it have on your admiration or purchase?

 

Good to know, rebuild is looking like rebuild is a good option, just would need to consider any time it would take. It is not a daily driver, but I'd like to get it in about a weeks time.

 

On the S Types you will often still get a charging warning lamp after fitting an aftermarket alternator as the control modules are different.
I don't know if that's an issue with X150 but if so it's another reason to rebuild.

 

Thanks Norri. This is exactly the info DIYers are interested in. Auto parts guy also mentioned that for some later models a reset may need to be done if alternator is changed. I am hoping that is not the case for the 08 XKR.

 

I had to rebuild my X100 alternator; it was a drop off in the morning on Monday and pick up Tuesday afternoon. I worked 2 miles away so not a big detour. Most of these shops are VERY quick. At my work I coordinate with electric motor, pneumatic and hydraulics shops occasionally for automation equipment and even for full custom stuff, turn around can be fast; but stuff like a Jaguar alternator should be plenty fast .

 

There appears to be a number of reliable major parts sources for these rebuilt with warranty for around $200. I reckon this is your best choice. I wouldn't go with aftermarket.

 

Thanks, I think you are right with the turnaround. Just talked with local shop and 1-3 days depending on if replacement parts are in stock. Not bad. The price was quoted at $125 - $150 however.

 

The remans typically come with a 1 year warranty, would ask your shop what their's is.

 

Been a subscriber to FCP Euro for a while now and they cater to the EDM. They carry Bosch units for the Jag. I have been meaning to try them and their lifetime warranty for everything they sell would be quite attractive. Free 1 day shipping as well. Question remains, new Bosch unit vs. rebuilt original unit.

 

Procrastination must still be legal in Massachusetts.

 

HAHAHA

 

It is called research if you are referring to my intentions. Impulse buying usually benefits the seller greatly. Not all have unlimited resources. Please keep personal attacks and way off topic comments to yourself.

 

Remove sticker! No intention of performing any deceitful act, but the insinuation is also not appreciated.
