I've a problem with the engine dying when I engage the PTO, I tested the PTO and it's good but there's a diode In the wiring harness to the PTO. It's cracked but still ohms out ok (one way pass, other way resistance 7k ohms). I can't read the part number, do anyone know the part number and what's it do?

USE 1N5407-G
It's there because when the pto is turned off, the collapsing electric field within the coil causes a big, large surge of current and voltage, which causes problems w the electric system. The diode stops it.

Unplug the PTO from the harness, then check to see if it will keep running. This favors a safety switch issue.
The PTO clutch diode is there to prevent a voltage spike back into the harness when the electric PTO is disengaged.
Star Tech gave you a parts source, but you need to make sure it installed the same direction as the old one for it to work properly, or the PTO clutch may not work.
