Identify this light switch & its terminals

RTR · Nov 11, 2010

Here is an original light switch that is on my Farmall Cub. It looks to me that there is a fuse holder built in on the switch (I know I will need one for it to work). There are also a couple of wires/terminals under the fuse location that I am unsure of and what they "power".

Here are some pictures of the back of the switch and see if you guys see the 2 wires/terminals to the far right and the bottom of the switch. Thanks so much for all of your help!!!

Looks like the original lights/charge control switch for an early production Cub.

The fuse holder is for a fuse to protect lighting circuit. It takes a 20 amp glass fuse (SFE 20?).

The terminal at the bottom of the fuse holder supplies power to the light switch. It should be connected to the ammeter.

The terminal behind that (at the end of a resistor block) is for generator charge current control. If your Cub has the original generator cutout it should connect to the generator F terminal. However if the cutout has been replaced with a voltage regulator - or if the generator has been replaced with an alternator - this terminal is not used.

I have an 1964 Farmall 806 which has what looks like transmission fluid leaking from the right back side of the gear box area. My mechanic thinks that it is not worth his time to fix the problem. I am looking for another mechanic who is willing to work on my tractor in Pennsylvania, Maryland, or Virginia. Does anyone know of someone who will look at my tractor?
