Default Hifonics Brutus Bxi 2006D in protect

ok it would go into protect then removed driver board and would power up fine so had another driver board from another hifonics amp, identical to the original, installed it and would power up fine, then all of a sudden it would blow my 10 amp fuse when powering up checked output transistors in board and legs 2 and 3 on right bank of 6 would read 0 Ohms in circuit found the 2nd fet to be bad other 5 check good but what could cause excessive current draw even if the fets and driverboard are removed, ive removed 6 of the fets, and it powers up fine but seems to draw more than normal current, when i install just the driver board back in circuit it goes back into protect

Are you sure that you don't have solder bridges between the pads for the outputs or the driver board?

Transistors on the other side of the amp can make it appear that there is a short on the side with no transistors.

Are you sure that only one reads 0 ohms in the board?

0 ohms between which legs?

Between legs 2and 3 , I'll double check to see if others read funny, could it be the driver board? I could remove it and check the fets again?
