I have a 1976 cb705 trike. (custom!) it was working good last year but I changed the motor out with a spare I had,  cause it ran the cam dry of oil and damaged the end.  The problem I have is that I transfered most of the electrical over to the new engine and now when I hook up the silicone rectifier it blow the fuse instantly.  I have tried removing the alternator and voltage regulator from the equation, even yellow wires were temporarily removed.  when I hook up the green and red wires on the rectifier to ground and power it pops the fuse.  I've tried another rectifier with the same result.  I'm stuck.  The only thing that I can think of is that it all has to be hooked up and working to not pop the fuse. anyone, any help, please.....
