SOURCE: Which type of wire I should use to connect capacitor to magnetron
You were sent the wrong magnetron.
If the supplier will not give you the proper one, you can usually find
helpful exploded view diagrams and order proper parts by entering your full
model number here.
If you don't find it there, please reply back with your brand and model number so we can help you.
You would need high voltage wire, of course, but I would not recommend using the wrong magnetron in your oven since it is a critically tuned part, and will likely fail in short order if it is not the correct one.

SOURCE: Wires to magnetron
It matters!
The wire from the high voltage transformer high voltage tap goes only to one side of the high voltage capacitor. No other wire is connected to that terminal of the high voltage capacitor.
The other side of the high voltage capacitor connects to the anode (A) of the high voltage diode and to the "FA" terminal of the magnetron.
The cathode (K) of the high voltage diode is connected to chassis ground.
The pair of wires connected to the secondary (thinner) winding of the high voltage transformer are the filament wires and are connected to the "F" and "FA" terminals of the magnetron.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
It has the overall wiring diagram and schematic.

A good high voltage diode will read open in both directions on a standard meter. See: http://www.gallawa.com/microtech/diode.html
If the diode is NOT shorted or burned looking, it's probably fine.
There should also be a "mini-manual" hidden inside the unit behind the control
panel or hidden on the left side behind the grille, which is very
helpful when troubleshooting, & testing.
It has a wiring diagram and a schematic which shows you how the components are connected.
On one terminal of the high capacitor, there is only one connection - to the high voltage output of the high voltage transformer.
The other terminal of the capacitor will be connected to the high voltage diode and the magnetron, as well as one of the heater (cathode) windings of the high voltage transformer.
Here is info on testing the mag:

(continuity can be good even though mag is bad!)

The sensor you detail has no polarity. It can go "either way"
For goodness sake be careful, I don't want to scare you but more servicemen, & would-be-servicemen die each year "trying" to service Microwave ovens.
They are lethel, or rather the Main Capacitor is, it stores enough Joules to kill someone 10 times over.. Always ensure it is discharged to earth before working on anything.
Be careful.

That is probably a thermal safety. Be glad it did not turn on with the covers removed you can cook your self very quickly unless you are trained in servicing them.
