Its a talon with a blown transistor

[geomapguy]

Pretty sure that's a Talon that has been burned out...

It looks like a talon, I've seen the how its made on them

I didn't know that was possible...

Talon Flambe'

It's what's for dinner....................

[EricH]

Something tells me that the red leads and the black leads went into the wrong spots--the screws are all out of position...

Talon with a blown capacitor. You probably switched the input wires by mistake...

I agree.. Q12 leads (4) appear to have experienced high heat surge i.e. they are discolored.
& is likely one of the 4 bridge FETs (H-bridge power switch between input power & motor load)

often the result of a drain-source overvoltage spike "punch thru" which puts the battery across the switch without current limiting.. strange thing is 2nd FET does not appeared to have the same damage - as one is tied to +12 other to ground return (-)

The big cap looks fine.. debris on it appears to be adhesive or pealed conformal coating

Talons have diodes or something on their input leads to protect from people switching the two

I do not believe that is the case.

[Tungrus]

Its a talon with busted electrolytic capacitor, the ash/grey dry powdery stuff is the leaked and dried liquid.

[Gdeaver]

That is thermal compound. The cap touches the heat sink.

I can confirm that is not the case!

Been, there, done, that, have the magic smoke and a conversation with Mike Copioli, along with some hush money to get a replacement. No freshmen were harmed during the thermal event, or after I realized what they did. . .
