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?

Cheers

This is a photo of the burnt diode - or whatever componant- in the LRP Ai Pro reverse.
It doesn't go across the motor wires as I previously thought but goes across the pos and neg inputs. Presumably to prevent damage from reversed polarity! How ironic.
Any help appreciated.

send it back to helgar mate

ooooooh, lol how did tht happen? thts same esc as mine, lol hope mine dont turn out like that. i was lucky, i bought a capacitor off ebay and it worked fine until i lost the reverse side of my car. my esc could of blown up any time then.

The esc still works, in a fasion. The only issue I find is that i've lost dead stop between brake and reverse. So it seems that when brake is applied it just spins the wheels backwards. The more I stress on it, the more I think I'll sent it to Helgar and get a difinitive answer.

email them and ask the values for the diode (if you're capable of replacing it yourself)
