What I thought about doing was putting the jumpers between the batteries just like I was jumpstarting the car. Then I start the car with the questionable battery/alternator. Leaving the negative jumper attached to the negative cable on the questionable battery, I remove the negative cable from that battery and wrap plastic around it to insulate it. That way the alternator is attached only to the good battery in the other car. If the meter sees 13.7v, the alternator should be good and the questionable battery identified as being the problem. I have negative to negative and positive to positive with the questionable battery out of the picture. Wouldn't that work? Yes, that would work. But what if you slip? Craig Used to doing that. If so, just start over with new diodes, new regulator, new alternator, new battery, new car; whatever it takes.

Better - or more accurate - than measuring continuity is to measure voltage drop.

If there is more than 0.25 V drop, it's worth a closer look. -- Philip Good idea; didn't think of that. I'll try it tomorrow.

Gerry No, the voltage on the green wire will follow what the battery and the alternator are doing. If the alternator is properly charging the battery, it can go up to 14.4 volts. If the alternator is not charging the battery and the battery gets discharged, it can go below 10 volts.

They are meant to charge first, then start. Heavy cables are not cheap and most people do not own a $100 set of jumper cables capable of starting a Diesel. Yes, charging only isn't a big deal and completely safe as long as he is careful. Not even really likely to damage the diodes swapping terminals as long as nothing is crossed.

This is nothing more than jump starting the car as far as the cables are concerned. Nothing is going to burn up here. In fact, what will probably happen is the alternator will begin charging the newly introduced battery since the questionable one was run dry, thus has a high resistance cell eliminating the ability for the battery to be charged by the alternator. He's looking for 13.7 out of the alternator which is correct, and should be achieved if A) the alternator is capable of charging, and B) the battery is able to be charged. It's a simple test, takes seconds, and is accurate. It can be done in business clothes. It eliminates or proves half of the A) and B) above.

Has anyone ever seen a fire from jumper cables in anything other than a dream?

He apparently had no problem starting the car. First thing I know, someone comes screaming into the room that there's gonna be a fire. Now *really*??

Re: [MBZ] Alternator question '83 300D
I saidif.he was using the starter he better have bigger cables than most folks have. Simple facts my friend. The wire in a 4ga. set of cables will not hold up to the current draw from the starter and may burn up when trying to start a Diesel engine without the battery in the vehicle to be started supplying some of the current. I say that is a fair safety warning, not trying to scare anyone. I have burnt up cheap cables doing just what I warned about.

Re: [MBZ] Alternator question '83 300D
There you go again, you passive aggressive or what? Do you not recognize that your very first line is looking for a fight? If you talked to me like that in person I'd walk away. When I was younger I'd have hit you but I'm a bigger person than that now. Yes I've seen cables melt. My great uncle Reg (who had plenty of money) grew up during the depression and was a great one for buying the cheapest anything that would do the job. He carried the absolute worst jumper cables I've ever seen and patched them together with as little tape as he could get away with. Finally went to jump a car for a lady in a parking lot, I made the connections (of course he made me do it) and when she hit the key both wires at the truck end burnt right off. He was very upset when I wouldn't try to fix the cables. -Curt Date: Wed, 4 Sep 2013 10:54:11 -0700 (PDT) From: Richard Hattaway rhatta...@rocketmail.com To: Mercedes Discussion List mercedes@okiebenz.com Subject: Re: [MBZ] Alternator question '83 300D Message-ID: 1378317251.51648.yahoomail...@web161003.mail.bf1.yahoo.com Content-Type: text/plain; charset=iso-8859-1 Has anyone ever seen a fire from jumper cables in anything other than a dream?

If the connector wasn't the problem, will put a good regulator in and try it. If that doesn't work, will chuck the 3 used alternators in the drill press one at a time and try the half dozen regulators (hooked to the 12 volt shop battery) until I find a good combination.

Gerrymostly talking to myself From: Gerry Archer arche...@embarqmail.com Sorry to interrupt this ongoing discussion about Rusty and Trent and Gary, but I have a question about the alternator on my '83 300D. There are three wires coming out of the alternator. Service Manual SM-1243 shows that the two heavy wires, same color, are common inside the alternator. It also shows that these two wires terminate at a buss bar on the right rear inside front fender. This seems unusual having two common wires originating and terminating between the alternator and buss. The only explanation I can think of is that MB is dividing up the 60 amp load between two wires instead of having one larger wire. The manual also shows the battery connected to this buss but doesn't show where. Can someone tell me where the wire from the buss to the battery connects to the positive battery cable so I can check it's continuity and clean the connection? With the key on run there is 12v on all three wires to the alternator. With the key off, there is no voltage on the small green wire and still 12v to the other two heavy wires. It is a new alternator, but it still doesn't show 13.7v when engine is running 600 to 1200 rpm. Also, where is the ground strap from the frame to the engine/transmission?

Re: [MBZ] Alternator question '83 300D
Ever try to start a car where the battery in the car is dead? It takes a helluva lot of current to get a car started. Normal battery cables are so short they don't have to be all that thick. Now you want to run from one car to another your cables have to be thick to make up for the distance. I'm sure theres a rule that explains how thick for the distance. Mercedes diesels in particular take a ton of power to get started, theres a reason the battery is a grp 49. Most jumper cables are garbage, like 4ga. I've got a set of good ones that are 0ga that were like $90 and are heavy. People joke when they see them but they'll haul a lot of power. One time jumping a co-worker's car I didn't have my cables so we put my 240D with some wimpy cables somebody had and nothing happened.

Re: [MBZ] Alternator question '83 300D
He never said his car wouldn't start. He said the alternator won't charge. And there is an opinion that the battery is the culprit. If the car is hard starting too, then he has to use real jumper cables. Nothing else changes. Geeze, you guys are a bunch of alarmists. Well, one or two of you anyway... Sure, he can swap the batteries if he wants to. Fine. My point is that it's an easy check to see if the battery is the issue, and to not wait until after he's tried three regulators and set up an alternator test bench with a drill press to sort out the culprit. And if he does it as I described, he'll already have it done while you guys are all standing around kibitzing about how it wont work for this or that reason.

Re: [MBZ] Alternator question '83 300D
OK, it's not a good idea to remove a battery from a turning alternator. So this is not a good plan. I was thinking more along the idea of disconnecting the 240 battery from it's car ( pull the cables off ) then jumping the 240 battery over to the 300. The 240 battery is still in the car but not connected to the car. If you have no issue starting the 300, it starts easlily with the questionable battery, then I'm thinking it's not the battery that's at the root of your charging issue.

If an alternator acted as a simple supply of E in said equation, then yes, this is true. One could also insert an R with a value of 0 and have the alternator provide infinite charge. However, an alternator actually depends on the battery for excitation of its field windings, and a battery with a high resistance cell will normally cause the alternator to not charge.

Re: [MBZ] Alternator question '83 300D
Yep, slipsies might introduce more questions than answers. Just make the 240D bare posts, and set up the jumpers. If you get 13.7 when the 300 D is running, then look at the battery in the 300D closer. You really don't have to disconnect the 300D battery to make the test. I think you are going to see 12.7 with both batteries. But then you've scratched off one of the tests you wanted to run pretty early in the game. Did the new connector help any??

Answers among the questions From: Gerry Archer arche...@embarqmail.com To: Mercedes Discussion List mercedes@okiebenz.com Sent: Monday, September 2, 2013 9:00 PM Subject: [MBZ] Alternator question '83 300D Sorry to interrupt this ongoing discussion about Rusty and Trent and Gary, but I have a question about the alternator on my '83 300D. There are three wires coming out of the alternator. Service Manual SM-1243 shows that the two heavy wires, same color, are common inside the alternator. It also shows that these two wires terminate at a buss bar on the right rear inside front fender. This seems unusual having two common wires originating and terminating between the alternator and buss. The only explanation I can think of is that MB is dividing up the 60 amp load between two wires instead of having one larger wire. This is the reason The manual also shows the battery connected to this buss but doesn't show where. Go to the fender ( passenger ) and look under the air cleaner/turbo stuff. There is a block there as you describe. Has a few wires on it. Includes the alternator and the feed to the soleniod coil on the starter if I am not mistaken... Seems like I could always find a way to crank the engine for valve sets there. Now there will be another lead that goes to the battery, probably hooking to the starter battery post but not sure. You have to trace it, physically. Can someone tell me where the wire from the buss to the battery connects to the positive battery cable so I can check it's continuity and clean the connection? Sorry, see above, I got carried away.. With the key on run there is 12v on all three wires to the alternator. With the key off, there is no voltage on the small green wire and still 12v to the other two heavy wires. It is a new alternator, but it still doesn't show 13.7v when engine is running 600 to 1200 rpm. The smaller wire is what feeds the light on the dash IIRC. So no ignition, no circuit. The alternator sounds a bit bad. It has a built in regulator, and should pop right up to 13.7 when you spin it up. What does it show?? Does it move up at all? Also, where is the ground strap from the frame to the engine/transmission?]] Again, IIRC, it's under the driver's right foot, so to speak. Braid/strap arrangement. Pretty obvious when you climb under there for a look. If the car is cranking OK, then it's probably OK too, since that's the return for the starter current. Be sure to check/replace all the fuses ..
