Wiring Diagram needed for a 1979 DOHC CB750
« on: November 27, 2006, 09:59:49 AM »
I know we mostly deal with SOHC bikes, but, trying to help a friend find a copy of the wiring diagram for a 1979 CB750 DOHC with the electronic ignition. I searched thru the normal resources from our website here and did a google search to no avail. Any help would be greatly appreciated. DrMark

There are two global DOHC sites:

www.cb1100f.net
www.cb900c.net

They should have something there.

here is the whole service manual online:

1979 750F addendum - pages 7 through 9 have the wiring diagram:

page 4 explains the components and general features of the transistorized ignition:

and a general flow chart for troubleshooting motorcycle electrics:

and just for giggles a pic of my former 79 DOHC 750F that now belongs to my brother:
