One thing I want to point out for safety's sake, is that no matter what you do make sure that the safety starter switch (#13 in the diagram) is connected and functioning correctly so the tractor can't be accidentally started while it's in gear. more
On most starter and ignition systems I've seen, B=Battery, I=Ignition, and S=Starter. [links]
My tractor is a little different than yours, but the neutral safety start switch should be in the same location. Here's a picture showing it's location. [links]
You're welcome. Unfortunately, I only had a diagram for a Massey 135 equipped with a generator because that's what mine has, but I'll keep looking to see if I can find a diagram for a later one equipped with an alternator. Alternatively, someone else who has one may eventually reply. here
Starter solenoids come in two types. Firstly, you can use the on-starter solenoid that directly mounts on your car’s starter motor. [links]
Three-pole solenoids follow a similar procedure. However, they do not come with a smaller terminal for the ballast resistor or ignition coil connection.
A neutral safety switch prevents your car from jerking when the engine starts. The neutral safety switch usually works the same in automatic and manual cars, using the inputs from your car’s PCM to engage. more
For your engine to start, it needs a high current which usually comes from your car’s battery. The cables that carry this charge from the battery need to be thick enough to withstand the high amount of electricity flowing through them. When you look at your car battery, you usually see two cables. These are the cables that connect the battery to your car’s starting system. First, the red one connects the starter solenoid to its positive terminal. This wire is usually live so be careful when handling it. Then, a black or greenish-yellow cable connects the starter motor to the battery’s negative terminal.
Below is how you can wire a four-pole solenoid.
Just wondering. I am planning on putting a 52 car engine 216 in my 48 3100. I plan to use Woody's diagram to drill the front mounting holes. It has the key start solinoid on the starter and I was wondering how I could use a key start or a push button. I was hoping the key starter from a 52 (or some other year) would fit into the existing key starter part in the dash for the time being. This engine appears to be good so I wanted to use it. And, if this engine doesn't work out I will find a good 235. [links]
Now you need to have the ignition switch (key switch) wired to provide power to the coil when the key is turned to "On". Another complexity is that the foot-starter switch might have a small post on the side that would be wired to the coil (to give 12v to the coil while the starter is cranking).
You do not have original 1952 wiring if you have a 12v system. more
Thanks Tim, it is really hard to read. My 52 AD came with a starter button on the dash with a key switch. Key cluster has three prongs one red hot wire is connected to the key and there are couple of blue wires goes to the starter button. whoever originally convereted to 12V used all blue wires so it was really difficult to findout which blue wire go where.
If it is cranking when you push the button, you are sort of half-way there.
This is how a 4-pole starter solenoid switch is connected. One of the larger terminals is connected to the hot wire coming from the battery, the second large terminal is connected to the starter, the first smaller terminal (S) connects to the ignition switch, the second small terminal connects to either ballast resistor (R) or ignition coil (I) and is generally unused. Make sure to ground the frame.
