GM Alternator Over Charging

So I converted my Oliver 77 to 12 volts and I used a later style GM alternator. The alternator I used is the internally regulated 63 amp unit that was produced in the 70's and 80's. I got a brand new one from my local NAPA auto parts. The rather knowlegeble gentleman at NAPA gave me a handy little diode pigtail that plugs inline with the regulator plug that allows the tractor to shut off so it is not kept running by a voltage feed through the alternator / regulator, and that makes sense.

So far, everything works great! And that is the problem, it won't quit charging. It cooked the battery that is in there as it over charged it. Some have said that as far as they can tell, I have it all wired correctly and that the battery was the problem. I guess the battery can cause it to over charge? I guess I have never heard of that. I am thinking that the alternator may be defectective in the sense that the VR isn't working correctly.

Anyone have any Ideas? Do I need to add a resistor to the battery feed from the alt to knock down the current? I wouldn't think so. Or is this just the classic sign of a defective voltage regulator?

Thanks,

Jordan

The alternator's #1 terminal will be fed power from the ignition switch through the diode.

The alternator's #2 terminal will be jumpered over to the alternator's large output stud for voltage sensing OR wired back to the battery cable for more accurate voltage sensing. (If this wire is not connected, the alternator will "default" to a higher charging voltage, 1 or 2 Volts higher than normal.)

If you have both terminals hooked up like that, you need to verify the charging voltage with a QUALITY digital meter, or an accurate analog meter. (CHEAPY digital meters tend to pick up electrical "noise" from the charging and ignition systems, and "freak out", giving inaccurate or scrambled readings.)

You should be seeing about 13.5 to 14.5 Volts at the battery. Much higher than this will "cook" the battery.

Be aware that a defective (sulfated) battery will get hot and boil when charged to normal level.

It's geared to the "hot-rod" set, but the Delco alternator and voltage sensing articles are just as applicable to tractors.

Bob,

Thanks for the info. I will check out the wiring one more time to see if it is right.

Thanks,

Sounds like you have a bad volt reg. Them old alternators do that at times even when new. I pull it off and take in in and have it checked. I even got new one that would not work as it should.

Yes, you are right. I love this old girl. It is in great shape. I bought it about a year ago stuck for $200. Some young kid had got it when his grandfather died just let it sit outside for a year or so. It is in great condition, and still has the original dealer sticker on it (Says "The Farmers Store, Mineral Point, WI"). I had it broke loose and running a couple hours after I got it home (Tri-Flow oil is the best i've seen for this by the way). It now runs great. It uses about a quart of oil pulling 2-16's per 10 or so acres. When the time is right, I may give it a paint job and a new set of rings, but she hasn't asked for it yet. As a stable mate, I also have the 1st serial # of 1945 Oliver 70.

I would definately buy another 77 or even an 88 for that matter. I would probably look for one with hydraulics on it as mine doen't have it. Although it doesn't qite have the snoot that my Farmall M has, I like it as well.

Shoot that 77 should pull circles around an M. An M is rated at 36HP and the 77 is rated at 38HP. But as you said it may need rings. I had a farmall 450 that I sold because it wouldn't run my baler as I wanted and got a S88 and it just plays with the baler. Both the 450 and the S88 are 55 hp tractors and the S88 pulls circles around that 450 I had.

My M makes 44hp on the dyno so I think someone has warmed it up a bit in the past, but I've never had it apart so I don't know what has been done to it. It also has a wide front, hydraulics, liquid in the tires and hub duals so it weighs in at about 7500 lbs. I pull a 16 ft JD disk in 2-3 gear with it. I don't think my 77 would do that even if it were fresh. When I pull a few wrenches on the 77, I plan to warm it up a bit as well, so we'll see how it does then.

I think I'll take the 77 to a couple of tractor pulls soon to see how it does. I think it still has good power, just uses a little oil. Maybe its the valve guides. Come to think of it, it does smoke when it starts up after sitting. I don't know what the 77 weighs, but I would guess around 4000 lbs. It has the cast iron rim centers, mechanical lift, belt pulley, stamped front rims, and no fluid in the tires.

Should be fun!

Sounds like you have a 1949 77 but just a guess, I figure that because it has the lift instead of hyds. They put hyds on in 1950. I just sold a 1949 77 that went to KY. I still have a 1950 and 1953-77 and a 1955 S88 and an OC-3 and an HG crawler. A 77 should make a good puller, I hope the year to give pulling a try with my S88 if I get it done by this fall that is.

I'd like to have one with hyd's to use as a runner, and then use this one for pulling. I also have an OC-3. Mine has a Ware loader and a rear ripper on it. It is a 1953 and runs good. I hear that they are worth quite a bit these days.

When I got the 1949 77, he gave me the complete set of belly cultivators with it as well. I might try these sometime. Quite a pile of stuff to bolt up to the tractor, but all in great shape,

Both my OC-3 and my HG have laoders on them but they don't really have enough power to really do much with the loaders. The 1953 I have is for sale by the way.
