How do you check a bridge rectifier in circuit to be absolutely sure
it needs replacing. Conditions: No power applied as 2amp fuse in the
transformer primary blows immediately power is applied. Usual short
circuit procedures followed throughout but I don't place too much
reliance on this test . BTW, the rectifier (B40 C3200/2200)) is in a
theatre organ purchased from an outfit no longer in business and space
on the pcb is at a premium and discourages using single diodes.
Thanks - John



Remove it from the board and check the individual diodes with an ohm
meter, they're all accessible from the pins.

That's not "in circuit."
