Default Re: Another HannsG HG281D

So at this point what Voltage do you have on the Source pin of Q14, 0V?
0V also on the two FB?
There should be big wide copper trace from the POWER 12V pin on the connector all the way to the Source pin of the MOSFET or to the inductor first before getting to the Source pin.
