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!

a reverse speedo should not have a diode on the motor wire!

There's def. a diode across two wires in there!
I'll double check which wires they are and repost.

Mark is spot on, a Schkotty diode is polarised and therefore can only be used on forward only ESC's. If you put it onto a reversable ESC, it'll go bang the first time you hit reverse.

If unsure, consult the manual and follow that 100%.

Is this a capacitor ?

Funny when they blow up though

I kinda want to know the same thing.
The basic motor that I purchased has no capacitors or Schottky Diodes. what Size/rating do I need? Can they just be purchased from Maplin? if not where?
