MF diesel 65 won't start.

it use to start just fine every time. Now it won't. I found a wire the had popped off. Put it back in and it started right up. Drove it around the back field. Park it, turn it off, and now it won't start. The wire is connected. Should I try to get it to connect better? I wiggled it a bunch but still nothing. Not even a click. The connection is at that 1 1/8 plug behind the engine under the battery with a wire going to and from it.
 
The switch with the two wires should be your "neutral safety switch". If you can connect the two wires on this switch together...you can see if it will start then. If it does your switch may be bad, or a connection to it.
If you cant easily, connect the two wires, try shorting the starter with a screwdriver. But....MAKE SURE YOUR TRACTOR IS NOT IN GEAR.
short it by touching, with the screwdriver, the small post, with small wire, on the starter to the bigger one on the starter, with a small wire going to it. this is just a way to eliminate your key switch and all the wires to and from the starter (the two small wires make a circuit to the key switch when the key is turned to start). if you get the starter to work...you may have a bad key switch or wire somewhere.
If you still don't have any power, you may have a poor ground on the starter, or battery.
Sorry, if this is confusing....I find it hard to describe to someone how to do something like this, without doing it myself.

Reminds me of all the safety inter-locks I have on my MF. I have to remember to have all shift levers in N, the fuel red knob IN, the PTO lever in N, the wires actually ON the neutral safety switch, not fallen off... ... I forget what else. Deader n a hammer otherwise.
 
Connected the 2 wires at the neutral safety switch and nothing. I'm guessing it needs new wires as they're all pretty messed up. So are these the terminals to short to see if the starter will work?

Put new connectors on the the wires going to the neutral safety switch and went through the connections and it runs again, even though it's only 38 F. Thank you Wayne! Taught me a couple things about this beast I never knew before.
