(Help) Bridge Rectifiers, Late 80s Williams pins

[PinPal]

Trying to sus out a bad bridge rectifier on my friends Bally Mousing Around.

The game is way down the south coast and the boards have been sent up to me for Rod to test as the game was blowing Fuses on power up.
Rod from the pinball people checked all the other boards and found them to be ok.
My friend then sent the power board up to me to test.

What I want to no is with a Digital Multimeter how doo I check the bridge rectifiers to see if they have gone bad or are ok ?

This was my Mousing Around I reconditioned and sold to him sum years ago.

A bridge rectifier is only 4 diodes shoved into a box and wired together. You can test each diode individually although it isn't a definate test as they can read OK but fail under load.

As of anyone would doupt mike bit he is spot on.   If there is any doupt just swap it...  Too many times have they tested of just to fail under load

+1, i usually just replace them if in doubt. I find it quicker to just replace them rather than muck around testing them, as they are pretty cheap anyway.

+1 on the above.

which fuses are blowing?

Thanks for the info guys,,  from memory he said  F5 - 2 amp sl-bl Fuse will blow on power-up.  Will replace the rectifiers just to be shure. My Williams Bad Cats has the same Aux Driver Board but I don't want to test on that, might cause more problems.
