Honda CB450 "Layered" Color Wiring Diagram *FIXED*

manualofman

i always wind up with extra bolts leftover..
While I've found the clarified wiring diagrams (Like Glen's) and other colored versions, sometimes its still difficult to follow these things when wiring routes overlap. So while I was bored at work on Friday, I made this in Paint.net (a freeware Paintshop-like program).

http://www.manualofman.com/wp-content/uploads/2013/02/Manualofman.coms-HondaCB450-5Speed-Layered-Color-Wiring-Diagram.rar

Using the US 5-Speed diagram found in the CLYMER CB450/500T (65-77) book, I colored each circuit as a separate layer, so you can hide/show layers as you like to isolate the specific wire color. I also emphasized the splices. The only downside is you can't print it, so you'll just have to be careful not to ruin your laptops with greasy fingers.

Heres a preview:

It's a .pdn file inside the .rar file. I couldn't upload .pdn to my Wordpress blog, so you'll have to unzip it.

Paint.net is available for free here:

It's pretty powerful and I recommend it for those of us who hate MS Paint and don't want to buy Adobe Paintshop...

Let me know if anyone finds this useful, I can do others.

Its funny just had this discussion on twins about that exact diagram. Clymer has the coloring and the connection wrong for the regulator, there is no red connection to it. Should be yellow green and black.

Using that diagram as such will possibly cause damage to the harness and the battery.

Love paint.net btw, I use it all the time.
 
Re: Honda CB450 "Layered" Color Wiring Diagram

The red wire should be a green ground wire......That is where the regulator shunts the AC from the alternator to ground to regul;ate it. If you hook up that way, you will not regulate, and when the volts get above 15V, it will start shunting AC into the DC circuit....Being unregulated, you will overvolt and blow bulbs and possibly hurt the ignition.

Fix it fast!!!

But otherwise, what a nice effort.....Care to do some other models?

Thanks guys, I'll take down the link and repost up once it's corrected. I'll also compare this one to Glen's, or the one in the Honda Service manual. It still surprises me that manuals can get stuff like this wrong.

I wish I had a working copy of Visio still, because I would just scrap it and make a better organized diagram.

if you guys want other models, all's i need is the diagram itself. for this one, i just did a screen shot from a PDF copy of the manual.

Colour diagrams rule, much better than following a thin black line across the page then somehow ending up on a different line at the end :)
 
That looks better, still have the connection labeled red though.

Now, there are few other things not like in the shop manual diagrams that would confuse but not really harm the bike.

The RED coming off the rectifier is actually red/white and it shares a ring terminal with the red for the fused power AT the starter relay. The battery POS cable connects there as well.

There is also a Green with a ring terminal coming out of the harness right at the negative side of the battery, took me ages to figure out where that went.
 
Dude, those are the same problems I had with my bike! Im happy to know other people had it and it wasnt something the PO had done to mine. I'll try to draw those in and shoot it your way to check out first.
 
Question: If you have 2 wires of the same color going into a connector with 2 other wires of the same color (all the wires are black), should they all join to gether?
 
All of the same colored wires connect together somehow. In the stock harness that is done either with soldered splices or multi-way bullet connectors.

Otherwise yes. ;)

Frogman is correct. I always go for bullet connectors (or equivalent) rather than soldering so you can still pull out the component or branch of the circuit for troubleshooting/replacement/etc. I'd only recommend soldering together main branches coming out from the main wiring trunk..Like splicing together returning grounds where the "up stream" ends are coming from a 2-way or 3-way connector. The "down stream" end is usually terminating in a ground to frame.
