My 12 year old son brought home a MF 7 that he bought for 5 dollars.  It needed some work, but we have it running.  The battery will not stay charged and after digging into it we have found that the regulator is missing.  How can I determine what regulator is needed?  Is there an aftermarket option available.  I have found a Massey Ferguson part for $200.  This is a little more than I want to invest in a $5 tractor.  At this time he just wants to use it as a working tractor/mower, not restore to original condition. 

 

With his purchase he also got a MF 8 parts tractor.  This one had the regulator on it, but it is in really bad shape.  It is a REPCO FG 4720 B (I think it is a B anyway). 

 

Any thoughts would be appreciated.

Some are 10 amp, some are 15 regulators. Don't know for sure what a MF7 would use, but I would say a 10 amp is what's used, if it had the electric starter and light kit.

It looks pretty similar to the ebay regulator.  The three pins are lined up though. 

 

If I get the wrong one, would it "cook" the battery?

 

Thanks

Three pin in a row is 10 amp. The other one is 15. As far as I know. I have a book on the MF 7. I'll look tomorrow and see if it says anything about the regulator. Or maybe check the manuals on this site there maybe an answer there.

Welcome to GTT. My son got interested in GTs at age 12 too. Download the tractor and engine manuals from our Manuals Section. Teach him the basics of maintenace and mechanics. Pretty soon he may even look forward to cutting the lawn. BTW, he did very well on that deal. Good Luck, Rick

Two different regulators showing in my book. Depends on serial number. Hope this helps.

Looks like they are both listed as the same Massey part number 517414M1in the online catalog as well - I would assume at one time the unit with the wires was superseded to the one with the connector. 

 

Just as an fyi a lot of the Massey Ferguson lawn tractor parts catalogs can be viewed on line at

 

http://www.agcoparts...oksN/login.aspx

 

There is a button where you can log in as a guest user to view the books.  Click on the button and select to browse books at the upper left corner of the screen.  Click on Massey Ferguson, parts books, grounds care equipment, lawn tractors and select your model.  Hope this helps someone.
