Well that is weird! Have no idea why those would not show up in the search I did. Now getting over 600 hits on that. Will buy a few of those.
Thanks!

Received the capacitors and the 50 AMP rectifiers in the mail! No thermal conductive grease yet though. So would like to start with sorting out wiring up the replacement rectifiers. Have tried to sort out by studying the 6/12 volt switch how the rectifier is wired up, but have had no luck figuring that out. Have this thread to try to go by :

The upper two rectifier sections on the schematic are replaced by one of the new 50 amp units, and the lower two sections are replaced by the second new 50 amp unit.

On those new parts, the + and - terminals are the outer ends of the two rectifier sections and the "AC" terminals tied together are the center connection.

Thanks Mr. Detrola. Sounds like what I have been able to figure from the diagram and Bikenswim's posted solution on that other thread. :D

Got to dig up some scrap angle iron or aluminum to mount the rectifiers. Right now it is pouring and blowing pretty good outside. Tomorrow it is supposed to break and will see what I can find then. So for now will extend wires so can mount the rectifiers under the shelf.
