Besides, even if the old battery was salvagable, it couldn't have been better than a brand new battery, which they gave him for free, so he still made out better than having his old battery.
Sometimes, far from home, the easiest solution is the best solution. BTW, here is the thread about the Saab alternator that works in W123s: http://www.peachparts.com/shopforum/showthread.php?t=93569&highlight=saab+alternator As I recall, it is an easy to find alternator, but requires you to modify the case a tiny bit, by unbolting the cover, rotating it a few degrees, and bolting it back on. Something easy like that. The thread will explain it all. peace, sam

may be right
Mr. Carlton, you may be right. You sound like you know quite a bit. But what if the alternator rebuild was bad? That battery may have not been getting full recharge on all the short trips I take around town for seven months. Having never gone on a long trip in a while, I may have never known my alternator was bad. I guess it would have just kept using battery.
Anyway, the new Advance Battery is on the charger here on my carport. I will charge the new Diehard too. Should I take it out of the car to do so? Or just leave it in and hooked up? Once I heard that sitting a battery on concrete would cause it to discharge over time. Is there any truth to this? I am guessing not. Chime in.

How long is the battery hooked up to this miraculous device? If the battery comes up OK, do they leave it on the charge for a few hours, or does the unit have a massive input current with the goal to charge it in one hour or less? |

I don't know
Looks like Wolf Walker who used to work there at Advance will have to answer that question.
Mr. Carlton, do you know if the 1982 300sd has the 55amp or 65 amp alternator? I think the tag is gone off of mine. It looks like the best price on the 55amp is $130. I do not have heated seats. But is that saab alternator a better bet?

But, if the battery was not being charged, you would be the first to know, because a diesel requires a good battery even in warmer temperatures. You could not drive the vehicle without a functioning alternator for more than about two or three days (estimation). If the battery is discharged, this simply means that it needs to be recharged. My thought, although incorrect, was that the old batttery was discharged and would function fine if it were properly recharged. But, if that sophisticated machine can determine that the battery will not accept a full charge even though it is currently dead, well then so be it. |

However, unless you plan to add additional electrical loads such as high powered stereo equipment or high powered headlamps or heated seats, the stock alternator will function just fine. |

would euro lights be high power?
I am planning to switch out my regular sealed beams for Bosch Euro lights. Would these be considered high power? Would I be better off to go to the 65 amp alternator?

I'd like your old alt to see if I can see what died in it, assuming you don't need it is a core(or even if you do, you can have my old locked up one)
I'm just curious. On the machine, I don't like them, that fast charging. It's not that it will charge a battery completly in such a short time, it's that the computer knows how much it should have charged with the high current input in a given amount of time factoring in the temp. If it does not "take" the charge to a specified level for the entered CCA, it's bad. And yes Advance will give out a new battery without much grief to a friendly customer(which I know Will is). Check the price on a rebuilt Bosch for that saab, if it's no more than the MB model, go for it. Clocking it around is easy. Installing it was anoying on my w123, but not so bad. We can do it in an afternoon.

I'd be sure to check your ground straps-failure to have a solid ground could cook your new alternator (diodes) as well as the old one-an extra one from the alt to the inside fenderwell is cheap insurance.

I killed 3 batteries in less than 2 years
In my jeep, I always attributed it to "vibes and heat" from off-roading...
When autozone replaced it the third time they said it would be the last unless I brought the alternator in for testing... Well I replaced the alternator and I'm going on 4 years now with my current battery. Robert

If I remember correctly they use different mounting brackets, I thought about putting in the larger one when mine went out but just wanted to get it back on the road and not fuss with it.

Often when a battery fails it is really just one or two cells that fail. If you look at a battery it is made of six cells and each cell is a two volt battery. Six holes to put water into. Often if you look in the holes in the battery you can see the white powdery looking sulfation on the plates. When one cell fails and you hook-up a charger you will often see the amperage indicator on the charger go pretty high initially and then fall off quickly to a lower rate of charge. This is based on an observation that I have made and discussed with others. I don't know the engineering background for this but it would be pretty easy to program into a smart battery tester. I suspect that under a load the discharge rate would follow a similar pattern. There are probably other simple tests that relate to other battery failures that can be easily programmed into such a machine. Last edited by TwitchKitty; 01-19-2005 at 05:57 PM. |

alternator replaced
I finished replacing my alternator yesterday. I fully charged the new battery overnight since using it without the alternator working ran down. Installed a rebuilt Bosch alternator with a one year warranty and free roadside assistance. $160 total.
The old alternator had a little bit of bearing noise on the shaft. Not much, but the last time it was "rebuilt" they put an non-Bosch brushpack/regulator on it and it failed in 7months. The indy I use said he gets tons of cars to his shop like this and that people need to stick to Bosch brush packs or they will not last but about a year. The rebuild of the original alternator cost $192. It lasted 7months, but I was stranded and out of town and had no choice. Lesson learned. This was not a difficult repair. The bottom bolt was awkward to get to. Otherwise I did have to take the old alt. to local shop and get them to switch pully to new one - cost $2. Nut was torqued so tight I could not get it off.
