Can I use a bridge rectifier to repair 94 115hp

[Rule303]

I have a Johnson 115hp, 94 model that seems to have a faulty Rectifier.
Ive done the test involving putting the grey Tach wire to either yellow or yellow/grey and no joy at the tach end. I have a brand new Faria tacho so Im pretty sure its not it. The Tach has good power and earth supply, needle gives a slight bump when key is turned to on.
Im getting AC voltage on both yellow and yellow.grey when the engine is running so the Stator/alternator end is functioning. My question is whether I can insert a bridge rectifier from an electronics supplier rather than replace the rectifier/regulator. Genuine reg/rectifiers are pretty expensive in Australia.
Im not a qualified tech, but Ive worked in the Automotive electronics field for a couple of decades, so I know one end of a diode from the other.... one ends pointy, right? ... just kidding!!
I have a wiring schematic for an earlier model engine, 1989, but it seems to apply in this area
Im thinking if I insert the bridge rectifier before it gets to the original rectifier, It would still allow the regulator part of the circuit to still work.
Id appreciate some advise as to whether this would work or if Im barking up the wrong tree. Any info or diagrams anyone may have would be good also.
Cheers
Gary

Radio Shack bridge rectifiers are often used to replace the rectifiers in unregulated systems. But your scheme to use it in a regulated system....I have my doubts. I just don't see how the regulator could work on rectified DC input. But of course, I've never tried it either.

If parts are hard to come by and...
If you're sure the rectifier is actually shot, try cutting it open.
See if you can replace a component in there. It ain't rocket science......
unless they paint over the serial numbers. Then its rocket science.
