Can you check these like the Ir21844’s ?
I know the pin configuration isn’t the same but wondering if you can check them like that?
The amp I’m working on is a Rockford prime 750-1D
It had full rail voltage across the speaker terminals all outputs test fine but it looks like some has either replaced the outputs or pulled them to check them and soldered them back in

In general, yes. For most all of these driver ICs, you're checking to confirm that the output terminal isn't shorted to either the high or low supply for that output terminal. You check both the high and low side drive sections.
I checked it like you would check the IR21844 all of the readings were in the K ohms besides the last one which was in the mega ohms
If the driver board was in the amp, the pulldown resistors for the outputs can make the readings lower than expected.
Were all of the readings for the various 2092s virtually identical?

There is only 1 2092 in this amp .
I can check other components in the output section to rule them out .
And do you happen to know if the IRFB4227 are the correct outputs ?
