gen to alt

[bob from ill]

just wondering what would need to be done if even possible to be able to convert from generator to single wire delco alternator. also remember its a positve ground system so it may not be able to be done at all.

 

[bob from ill]

forgot to mention. its a first generation d17 gas tractor

Easy to do. Ground does need to be changed from + to - and to do that you switch wires on the battery and also on the coil and your done with the ground change

Yep.

You can also get positive ground alternators.

Very true but most an made in England and or they will cost you 3 or 4 times more then a Delco 10si will cost

Are they made by Lucas? "The Prince of Darkness".

 

[old]

Yep a lot of them are and yes they are a pain in the back sides to work with

Alot of alternator choices with + or - ground.

I use the single wire - ground alternator that has been reworked to excite at low rpms for slow turning engines like on old tractors from The Brillman Company for seventy some dollars.

This is the Alternator I use.

Looks like the one I have on my WD. Works great. Have to pull the engine up higher than idle to engage it, though.

bob, there have been a zillion guys put alternators on old tractors, your not the first. TO start with you had a 6 volt system. Most guys upgrade to 12 volt. second the old unit was positive ground, your new system will be negative ground. all you really need to do is switch the battery cables. the starter will not run backward as you might think, it will be fine. if you have a magnito ignition, no problem. if you have a distributor, switch the wires at the coil. If you alread have a 12 volt generator, your o.k. to swith. If you are presently 6 volt, you will need a new 12 volt coil or a dropping resistor in the line to coil. Biggest problem is making the bracket. The most common alternator is the 10si DELCO. The newer CS130 Delco is more $$, but nice and small. I prefer to use the normal 3 wire alternator used on all GM cars, not the 1 wire unit built for hot rods. THe 3 wire is a little easier to get it to kick in and start charging. I can get you a couple photos and wiring diagram if needed.

drawing is the older 10SI, photo below is the newer (1985-1995) CS130 style.

I use the Delco alternator made for a 1980 Chev pick up no power any thing. Cost me around $35 plus a core which I have on hand 99% of the time and that is with a life time warranty so if it goes bad it cost me $000 to replace

I used a key ignition switch and put the #1 wire from the Alt to the Acc side of the switch,no need for a Diode ,I have a single wire Alt on my Super A but I have to go down a hill and push the throtle all the way to excite the Alt,The engine dont run fast enough for the Alt to kick in.

Change GRD. to negative and USE the standard THREE wire wiring system. The only thing I do different is to use a diode instead on the 10 ohm resister in the diagram. This way you will NOT be stuck with some special ONE WIRE alternator. If you ever need to replace you can find the three wire one at any auto parts store. I did Dad's two C-II Gleaners and My C-II and An Uncle C-II but it was sadly lost in a shop fire.
