Can anyone help me with the correct method to check continuity on the left hand controls of a 76 CB550?  I have Hi/Lo Beam head light, right/left blinker and horn.  In following the CB550k wiring diagram it seems I should have continuity between:

White (Lo) - Br/R (head light) - Br/Wh (Tail light) when switched to Low beam

Blue (Hi) - Br/R (head light) - Br/Wh (Tail light) when switched to Hi beam

Light Grn (Horn) when grounded and horn button depressed

Light Blue (R signal)-Light blue/Wh when switched to right indicator

Orange (L signal) - Ornage/Wh when switched to left indicator

I refurbished the left hand controls and everything seems to be connected correctly, sliding smoothly and clean.  When I hooked up to the main harness and set the ignition to position 1, I am only getting Hi/Lo and Left/Right signals.  The horn was not working and I was not getting power through to the Brn/Wh wire for the tail light and the speedo and tach lights.

I have determined through testing my ignition switch is working properly.  Now that I have removed the left hand controls and have them on the bench, I am only getting continuity through the light blue- light blue/ wh for the right signal indicator.  Any thoughts are greatly appreciated.  This is the last thing on my check list before firing up and vacume synch.  Thanks
