Hi,

I'm looking for info about this home-made rectifier that I learned about on an earlier post.
I'm having trouble finding which leads plug into the thing.

I know the battery and neg(ground) leads, but the other two leads aren't marked.

Does it matter which wires go into those other leads? They are the ign switch and alternator wires.

The pic(someone else's on the forum) shows two yellow wires, I have a yellow(ign switch) and a pink(alternator) on mine. The red/white(battery) and green(ground) are accounted for.

Thanks,

Richard Meese

red/white:  bat (+)  DC
green:  bat (-) or ground   DC
yellow:  AC
pink:  AC

It shouldn't matter which AC lead goes where, because they are each simply opposite ends of a LOONNNGG coil(s) of wire.

I picked up 5 of the same rectifiers.  Super cheap if you bought a bunch, so I did.  Now, I just need to pick up some of those neat heat sinks.

Good luck with yours.

Sorry if the yellow wire caused confusion - I didn't have any pink lying around. Honda used yellow for AC in most cases anyway. I used the stock plastic plug with new terminals, care being exercised to get the green and red/white wires in the right places. The AC terminals on the replacement bridge are marked with a ~ symbol.


I'm not entirely sure of the origin of that heat sink. Definitely a cpu cooler from an old computer - probably a K-6 but could be a relic like a 486. A couple of my pinball power supplies have heat sinks made from a piece of a window frame.....

This one from an early Bally game.


Future projects may receive some of this material...

The larger one was a stereo amp from a T-Bird, the black square off an Intel Xeon cpu(both need some cutting). A Chrysler engine control box had several of the smaller heat sinks on large power transistors - those may just end up on old bikes.

Happy trails.

Reduce, re-use, recycle.  :)

Love it.

Guys,

Thanks, I think I get it. The battery and neg leads are most important. The diagram shows everything going the ame direction toward the battery.

Tex,

I know what you mean. I don't keep all the colors around for my bike's wires either. Thanks again for the original post and pictures.
