It's a matter of size!

[philly]

Hi guys.
I have a LRp Ai Pro Reverse speedo and the diode across the motor wires has failed due to some numpty (me) connecting a new battery the wrong way round!

Does anybody know what size of diode is required to repqair this model. Unfortunately, being in two halves I can't read the size from the componant.

I'm presuming this diode does the same job as a Schottky diode would on the motor itself. Am I right in this assumption?

Thanks for any help!
