Topic: 750 starter motor wiring question

[holajeffe]

I am sure the answer to my question is super obvious, but as I am a total novice please bear with me...I was given a 1973 Cb750 with the engine out of the frame and wiring harness removed and I am trying to figure out which wire is the positive wire to the starter motor. 

While I am looking at the engine from the back on the left side there are two cables coming out of the engine-there is a group of wires (green, white, Yellow, Yellow, Yellow) that I am fairly certain is coming from the alternator, then there are two left over wires (green/red and blue/red) in that same group.  There is also a big thick wire coming from the starter that the person before me labeled "to negative battery terminal".

the wires coming from the starter solenoid is yellow/red and black but I can't trace it any further because the whole harness is totally a mess.

was the person that labeled that big thick wire wrong?  If not, where is the wire that connects to the starter is it one of the other two left over wires?

can anyone clear this up for me?
thanks.

Both have links to docs and wiring diagrams that will help.

But, for starters, the cable from the starter does NOT go to the battery, either terminal. It goes to the starter solenoid.

thanks guys!  I got it sorted out (I accidentally posted this question in two places on the forum and someone else pointed out that the big black cable was labeled incorrectly)...the person who had the bike before me must have thought the left terminal of the starter solenoid was negative so when he took it apart he labeled it as such. 


that was really throwing me, but now it's all clear!
