Rich,Ask Pappy and Craig Payne about this. I know Pappy has converted to the B&C 28 V alternator and Voltage Regulator.
Also ask Doug Sapp about a maintenance manual. The YAK manual has wiring diagrams as well as George Coy has a manual with excellent instructions along with diagrams on the power panel.
I just had a Gen Fail light so I am sorting through this also but my issue is the YAK panel. I can not get the 29 pin cannon plug on the bottom right of the power panel to disconnect. It is like the damned thing is welded!

Working thru wiring on CJ-6A B&C 35 amp alternator conversion. Accessed the original generator regulator terminal block (6 terminals) on the upper back/right side of the "false firewall" and trying to figure out the small wires on the far left/right end of its terminal block. I've attached my sketch of the terminal block referencing the Chinese diagram inside the terminal block as well as the B&C LS1A regulator.

Since the far left terminal small wire was bundled with the generator output wires, I'm assuming the far left terminal is a chassis ground from generator to regulator (terminal appears to have a chassis ground symbol, though upside down). When I checked continuity from generator end to regulator end of the associated small wire it was an open circuit...but given age I wouldn't be surprised if that was just down to a broken wire.
No idea what the far right terminal symbols represent and the purpose of that wire....
For the LS-1A reg, any harm in connecting the alternator end of the CH (-) wire to the alternator mount stud (engine case), and after installing a two terminal (+/-) splice block near the LS-1A reg, using one terminal to splice the old (-) terminal wires together (originally ran in/out from the CH regulator), and then running the LS-1A terminal 7 and ground stud to the same newly installed block (-) terminal? Other terminal would splice the (+) wires that originally ran thru the CH regulator.

I plan on leaving in the filter on the left side of the false firewall, assuming not an issue. Anything special to retain use of the same warning light/volt/ammeter as CH?
Are the two small unknown use original CH wires (far left/right of the CH reg block) needed for any of the above?

Left/right on sketch equates to port/starboard on airframe.
Thanks,
Rich
