Topic: Does anyone know where the wires run to on the rectifier?

[tonylong1]

I have a 1974 Honda cb750 hardtail bobber, with the bare minimum wiring, but i was wondering where all the wired coming out of the recitifer run to?  The reason i ask is that i have power and the bike turns over but i have no spark and i think i may have that wired wrong at the ignition switch?

It is all on the electrical print in the service manual. Have you looked at it? Do you have a copy? You can download it from this site.

 Have power where???
 What is your power reading?
 What is bare minimum no lights no horn no elect.start?
 You are not providing near enough information.

when i turn the key i have lights, and it cranks over. So my accesories are getting power from the ignition switch, and the starter is getting power as well. i just have no spark, which i know i have the coil running to the right spot on the switch, i just need to know where all the wires on the rectifier run and to what terminal on the ignition switch?

Also if the rectifier is wired wrong will that cause the bike not to start?

 Here is a link to a print that shows the wires on the rectifier
Do you have 12v. at the coils from the kill sw.? Do you still have a kill Sw.?
