To determine if Q6010 mosfet is defective, remove all power.
Meter in resistance mode.
Measure the resistance across the mosfet pins:
source (1-2-3) & drain (5-6-7-8)
source (1-2-3) & gate (4)
gate (4) and drain (5-6-7-8)
Post all measurements.
You can test each of the mosfets using the same method. If the resistance readings are low - the mosfet is defective. Best to post every measurement for a review.
