Just an update. I tracked down the previous owner who has owned it since new. He says he has not removed the switch and that it was working when he sold it to me. In order to start it the clutch had to be pushed in. He wasn't sure where the switch was but suggested it could be a neutral safety switch. Hoping someone knows or where a person could get a shop manual or something?

Hmm. That doesn't sound right. On mine the brake light switch and the clutch safety switch are the same part, one is on the brake pedal and the other on the clutch pedal. Could it be the wires are crossed? The connector is a two-pin trailer connector about six inches from the switch. Look and see if there is a switch on the brake pedal.
Yes, the switch is on the brake petal. I put a meter on the switch and the switch is bad. I assumed this switch was just for the brake light. The switch is mounted on a bracket under the clutch pedal. What I find odd is that the switch doesn't really do anything when you depress the clutch. Only when I push the brakes the circuit opens and closes. So you think the switch is for both brake light and clutch safety start?

No. What I meant is on mine there are two switches, one on the left under the clutch pedal and one on the right under the brake pedal. When I said "they're the same part," what I meant is there's two of them and they're identical. If your brake light closes when you press the brake pedal then it's wired properly, I just got confused when you said it was under the clutch (that's where my clutch safety switch is). And the brake light switch shouldn't do anything when you push the clutch.
Somewhere there is another switch that closes (or should) when you press the clutch.

hagrant,
Have you talked with Affordable Tractor to see if they have the manuals you need?
I have read through all of this thread and am really confused by your #14 post.
“Yes, the switch is on the brake petal. I put a meter on the switch and the switch is bad.”
So the switch is mounted on the brake pedal and it is bad. That would mean that your brake lights are always lit in a ‘bright’ manner?
“The switch is mounted on a bracket under the clutch pedal.”
How does this relate to the switch on the brake pedal?
“Only when I push the brakes the circuit opens and closes.”
Does this mean that the switch is working, brake lights are not always on, and only go to a brightly lit mode when the brake is pressed?

Hi,
I have not talked with Affordable Tractor, I will search them as I have not heard of them. I will try to explain better.
There is one switch under the tractor and its located underneath the floor of the tractor (Directly below the clutch). It is mounted on a bracket and when I press the brakes the circut on the switch opens and closes. When I press the clutch nothing happens which tells me that this switch is only for the brake pedal. (the brake light switch just happens to be located underneath the clutch area) What i mean is that when the brakes are pushed it opens and closes the switch mechanism and no there are no brake lights when I do this. Only when I took the switch off and connect the wires the brake light comes on and stays on all the time of course as there is no switch connected. Yes the brake light switch is bad. I put a meter on the switch to check. I jumped the relay and the brake lights stay on all the time.

Hagrant,
Here is the website for Affordable - Home of compact Jinma, Foton, and Koyker Tractors and Parts, Wood Chippers, Backhoes - Affordable Tractor Sales Company
Is the switch mechanical or electrical? What is the connection between the switch (located under the clutch) and the brake pedal (i.e. how does the switch know that the brake pedal is moving)?
Now let’s talk about your starter-
The 12 volts to activate the starter comes into the starter mechanism through the small terminal on the Starter Solenoid.
Where does that wire from that small terminal go?
If it goes directly to the start switch on the tractor panel, I would say that there is no Starter Interrupt Switch. Note: I have no knowledge of the type mentioned earlier in this thread that mentions some type of sensor related to the transmission.
My 284 has an Interrupt Switch -in case this helps you:
There is a wire (#10 pink/white) that feeds 12 volts from #4 terminal on the starter switch to an electrical Interrupt Switch under the clutch pedal arm. When the clutch is depressed, it presses a ‘button’ on the Interrupt Switch. This causes the circuit inside the Interrupt Switch to close. This then sends the 12 volts on through a wire (#11 red) to the small terminal on the Starter Solenoid which activates the starter.
Regarding your question about wires from a sensor on the bell-housing. I have one of those and it sends readings to the tachometer. If your tach is working, disconnect those wires and see if it still works.

Thanks for the info. The switch is mechanical, when you press the brake it allows the switch mechanism to open. I will trace the wires back from the terminal to see where it goes...its been so cold so hopefully it will warm up soon so I can give it a good look. Will keep you posted.
Also, I did determine the sensor on the bell housing was my tach. It is not working...I unplugged it just to see if there were any changes but nothing.
