MOSFET failure simucube 1

[KOKO2ni]

hello, my SIMUCUBE 1 card seems out of order. The braking resistor heats up enormously, I think the MOSFET Q2 is out of order. Is there a solution to troubleshoot the card? thank you

Let the magic smoke out: smoked regenerative resistor and MOSFET cause by a stupid mistake

this was the original MOS-FET used but it is no longer available… there should be a suitable replacement though: http://www.mouser.com/ProductDetail/NXP-Semiconductors/BUK9575-100A127/?qs=me8TqzrmIYUywEOBdZqYAw%3D%3D Way back when Esa also gave me the P#'s of for an smd version of the mosfet, which could be used - BUK9Y22-100E,115 or BUK9Y15-100E,115 For the Braking Resistor anything 20w or above with a 2.2ohm resistance… Im using a 50Watt on mine NOTE: if you use a metal encased Power resis…
