Honda n600 Silicon Diode / Rectifier

Matthew Kiehl · Post by **Matthew Kiehl** » Tue Oct 11, 2011 7:16 am

Hello everyone,
I have been working on a 1972 Honda 600 sedan which is in need of just about everything. Anyways, I am at the point that the engine will start and idle, however, the rectifier appears to be a problem area for me.
Looking over the wiring diagrams, I notice that besides the 3 wires going into the rectifier, and grounding the rectifier to the car chassis, there appears to be a forth wire that runs to the main fuse (all which was non existent on this car)
Can anyone supply some pictures of how the rectifier should appear? It appears as if the output wire (which is what I assume is the AC current rectified to DC), just should be soldered to the non-grounded copper plate?
Thanks in advance,
Matthew

I am not sure if it'll help, but here's a page of mine with at least one pic of the rectifier.

yeah, I had seen your picture and realized that I truly was missing a wire. Ray from Eagle HD had sent me some pictures which helped, I now have DC voltage with minimal issues (some sparking where the copper wires run through the loops coming out of the diodes.. but at least the charging system is almost working)
Now to just get more than 12.5v out of it! :)
I still have yet to tear into the voltage regulator, file the contact breakers and regap according to the service manual procedure. At least now no melting wires and crazy arc welds
