I would like to know how to check the 6 volt generator to make sure it is working. I just got the tractor and the battery was very week and I have charged it, but it continues to drain when the tractor is running. I need to decide if it is the battery, generator, or electric short causing the problem. Thank you. I am sure you will be seeing alot of questions from me in the future so thank you for your patience.

Ajax,
I don't see an Oliver Hart parr Forum listed anywhere. How do I find it and I will post there. Going to be spending the weekend building fence, probably get back tothe tractor Monday morning so I am not in a rush.

Thanks

At the regulator, run a wire from the field (FLD) terminal to ground. Then take the regulator out of the circuit by connecting a wire from the ARM terminal to the BAT terminal. If terminals are not labeled, the ARM terminal runs to the bigger terminal on the generator, the FLD to the smaller terminal on generator, and BAT to the dashboard area. There may be a fourth terminal- L or LT- ignore it. Then check the ammeter with engine running- if it shows charge, which increases as you throttle up, the generator is OK but the regulator is bad. If you get no charge, generator is bad, and jury is still out on the regulator. If you have the regulator that's strapped to the generator, one of the terminals you need to play with is under the regulator- can't remember which one. Hope this helps.

Hey guys, ajax implement had it right to ground the field terminal as long as it has the original equipment charging system. That will probably tell you more than anything you can do. As for positive ground I always sooner or later switched them to negative ground like the rest of the world.

A kind of quick check of the generator can be made two differet way. If you unhook the field wire at the regulator and ground it and it charges you need a regulator. The generator can also be run as a motor. You need a set of jumper cables and a seperate jumper wire. If interested I get the details for you Friday or Saturday or e-mail me.

Yes, I am interested. Which is the feild wire. I have no experience with 6 volt or generator systems but I have an interest in learning.

A quick check for the ones who don't have testers is with tractor running disconnect a bat cable. If it keeps runig it is charging and of course if it dies it isn't.

Using the removing battery cable test the tractor shut off. So I guess we are down to the regulator and/or generator. So where does one go to have one or both tested repaired or replaced? Yep, complete newbie at tractor repair.

Even the one-horse town I live near has generator/starter repair shop. Ask around or look in the phone book.

There isn't much where I live now. It is a 40 minute trip to the auto parts store. If I still lived where I grew up (southern PA) I could have went to any number of neighbors or relatives. I finally located good sources in western Idaho but now I am in New Hampshire. I'll look around, really wasn't sure if I had to go to a tractor dealer, I'm sure there is a shop in Concord. Just glad it doesn't have to go to a specialist. Times like these us youngsters really miss having our folks close by.

Thanks I'll give that a try later this evening. I am going to check to see if there is a drain when turned off as well.

Olivers have a positive ground, check to make sure the ground cable is connected to the pos terminal on the battery. Hope this helps. Delbert

Do you have a voltmeter?
If so, check out the volts under different conditions, off, running idle, full throtle, with and without load (electrical).
Should charge at or near 2.4 volts per cell. Check ammeter on known current - zero with battery disconnected and with a known load, to see if what it indicates is near the truth.
Have you checked the battery capacity, electrolyte density.
Could be the generator, the regulator, the battery, a leak to earth or the drivebelt.
If an earth leak, you should see it on the amp meter or if too small, then with a suitable test meter, but make sure other circuits are disconnected first.
Best get yourself a vehicle electrical fault finding book and the wiring diagram for your machine and go from there. Alternatively, if you feel you are not confident of doing the job is get an auto electrician to check it over for you.
Hope this helps.
Regards, RAB

Thanks for the info, guess I am finally going to have to get an ammeter and hydrometer, should have had one after dealing with a truck that acted like this. I understand the concept just never worked with electric systems and have always been wary of them.
