The whistle diode is only in the circuit when the whistle switch is closed.

Since Olson's website went down, a lot of broken links back to them on this topic across forums.

Regardless, your first problem is what is wrong with your whistle switch before blaming it on the diode.

Second part is, why is there is a short circuit through the whistle diode basically between the U terminal and one of the other posts or windings- again, something very badly wrong with your whistle switch mechanism.
