What does the indicator light (next to the keyslot) indicate? As you can see it was painted over and wire is cut off on the back?

I answered this on the 'other' club Ford N Tractor web site. The first early 9N’s, til s/n 25000 used an Ignition ‘ON’ Lamp located just below the AMMETER on the lower LH dash panel. The Ignition Key Switch was also located on the RH dash panel a shown, and NOT next to the lamp as you show. Someone put an aftermarket key switch on the LH dash hole where the optional light switch was meant to go. Does lamp still work? If Your 9N may have been switched over to 12V so if your battery is 12V and you have an alternator, it would have fried the 6V bulb a long time ago. The OEM ignition lamp is NLA (No Longer Available) meaning parts are no longer available, except you can get the bulb so if all the rest of the socket is intact, may just have a burnt bulb. The MPC’s only list the dash lamp assembly as p/n 9N-3702, with no other individual parts except the lens, p/n 9N-3701, the wire, 9N-13603, and the Bulb, p/n B-13466. This is the same bulb that is used in the TAURUS taillight, industry standard #63. Like I said if your system is now 12V and you want to try the lamp, get a #67 (12V) bulb.

Found it. Thank you

Not the same website being discussed, but this website
gives some great ID and history info on Ford tractors.

I think he is referring to another site, the N tractor Club. Google it

it's a typo. intended to be "faRmerization".

N-tractors forum.

Isn't this the N tractor forum?

Like JMOR says, originally it was an ignition on light. Looks to be original. Not made any more and sought after by 9N restorers.

Quoting Removed, click Modern View to seeI expect some 'famerization' going on there, as key sw was never in that location. Light is correct for ignition on lamp. The other tractor form is a better bet as to exactly when the key was moved, when starter sw was moved & when ign on lamp was deleted. More restoration 'purest' over there. Other considerations are potential differences in dash for magneto equipped tractors or kerosene burners?

What is Famerization? This tractor has been he family since the 40s, I am quite sure this is the original location of the key switch. Also what forum are you talking about? Thanks for the information.

Do you know the serial number of the tractor? Is there a place for a starter button to the left of the ammeter? Are any of the castings for the steering gear or top of transmission made of aluminum, instead of cast iron?

Serial number is 15599 and as you can see no starter hole by Ammeter

It looks like you have a very correct tractor for its serial number. There were several changes in key position during that time, and your configuration could well be:

After the starter button moved to the bottom of the steering gear, after the key switch moved from the right side of the dash to the left side, and before the ignition indicator light was eliminated. It appears that these changes were introduced one at a time.

It will be interesting to see the rest of the tractor and compare it to what would be expected for your serial number.

Is the tractor 12V and have an alternator?
Maybe was a charge indicator light?
If it is 6V I don't know.

If the other end of the wire is still there, follow it back to see where it goes.
