HI, I HAVE A SERIAL# 101973 WHICH WOULD MAKE MY TRACTOR A 2N. I RECENTLY BID ON A WIRING HARNESS THAT WOULD FIT A SINGLE POLE GENERATOR.MY FORD FO-4 MANUAL SAYS 9N-2N'S HAVE SINGLE POLE GENERATORS. WHEN I DOUBLE CHECKED MY GENERATOR IS NOT A SINGLE POLE.(IT HAS 3 WIRES) IT DOES NOT HAVE THE ROUND CUT-OUT. I APPEARS TO HAVE A VOLTAGE REGULATOR. ACCORDING TO MY FO-4 MANUAL IT LOOKS LIKE IT IS WIRED LIKE AN EARLY 8N WITH FRONT MOUNT.BY THE WAY ARE THERE ANY GIVE AWAYS OTHER THAN SERIAL# TO TELL THE YEAR OF TRACTOR? MY SERIAL NUMBER SAYS 2N. FRONT SIDE PANELS HAVE NO BOLTS.(ALTHOUGH I JUST READ THOSE BOLTS CAME OUT IN MID-YEAR, AND THE WIRING ON THIS ONE IS MORE ADVANCED THAT 2N-9N ACCORDING TO THE BOOK. THANKS FOR LISTENING ER READING MIKE

It is possible to have a regulator on what appears to be an original 9N. When my generator needed rebuilding, I asked the shop if it was possible to eliminate the cut out and have a regulator. He said yes, I've done many 9N's and went on to say he probably works on 50-100 N's every year. He did some extra work inside the generator( don't ask me what) and gave me a regulator and said if you ever have any problems, you must replace the regulator with the exact same one. Also, he said if you need work on the generator, bring in the regulator at the same time. I've had it for at least 10 years.

Mike..... ..what jeb said..... .and..... ..
After the early 8N came out with a 3-wire genny and squarecan V/R, Ford offered retro-fit kits to change the 1-wire genny with roundcan cut-out relay to the better 8N 6 volt genny system. So to troubleshoot your 2N, use early 8N electrical drawings and wiring harness. The early 8N engine with frontmount distributor is otherwize identical to the 9N/2N engine.

Big clue: all 2N engine s/n's start 9N, 9N/2N's have 3-speed tranny and straddle the tranny left/right brakepedals, 8N's have 4-speed tranny and both brakepedals side-by-side on right side. Only late 8N engines have sidemount distributors. It just might dawn on you that all N-engines are fully interchangeable and after 60 yrs many have been swapped out..... ..Dell

I think that it is possible to attatch an 8N generator to a 2N generator mount. Also, your generator could have been rewired into a 12V configuration, which would explain a voltage regulator. The serial number on all 9N and 2N tractors begins with 9NXXXXX . Where did you get a 2N serial number (or did I misunderstand you)?

Basically, the givaways on 9/2N vs 8N are the rear wheels (Cast and square on 9/2N's and pressed, rounded steel on 8N), if it has a proofmeter (then def. 8N), if it has I-beam radius rods, then def. a 9N. I like to use the rear wheel centers as my benchmark and work from there.

Which side of the tractor is your generator on? If you are sitting in the seat, is it on the right (9/2N) or on the left (8N). This should give you a place to start.

JEB, ACCORDING TO THE BOOK I READ 2N'S STARTED WITH A 9N # THE GIVEAWAY WAS THE NUMBER ITSELF. MINE HAS THE 9N-2N WHEELS, 3 SPEED, 6V GENERATOR. POS GND. ACCORDING TO THE FO-4 BOOK EARLY 8N'S HAD A RECTANGULAR REGULATOR OH BY THE WAY MY SERIAL # 101973 WOULD PUT IT AT A 2N MFG. YEAR. I AM THINKING THIS ONE WAS COMPLETELY REWIRED. THANKS FOR YOUR RESPONSE MINE IS DEFINITELY A 2-9N BUT AM CONFUSED MIKE
