Nothing connecting to the power supply , its just a module ,
And I dont know what current and voltage , maybe 24v , and heatsink 6" by 8"
, so lots of power , as i said early its from RV.
I understand that the resistanse is low and very low , but if i tried 2 different meters and both showed 0, is that transformer problem ?
it has feedback and auto shut down , that why no burns on the transformer and on the PCB... anyways , i gave up on it , no chance to find new parts , google doesnt help . thanks everybody
