That is the one.
+DC INPUT fed into the MOSFET PQ1, check and see waht you have on pin 5~8 (in), 1~3 (out), pin 4 (gate).
Do the same on PQ2.
Check the current sensing resistor PR8 (6?).

I Can't find PQ1 on the board.

Well, I don't know what to tell you then, it is shown in your diagram you provided.

I see something show q1 I dont know if they lefted the p out by mistake, thats only one I see and it only has 3 pins. I did find PQ2 and that also only has 3 pins.

pr4 , pr8 has resistance, pr2, pr5, pr9 and pc2 don't. how do I test pq1 and pq2?
