CB360 wiring issue - no power?

[renslow]

Working on getting an old 360 back on the road and im having some issues. Im not getting any power from the battery at all. It's a new battery that reads 12.9 on the multimeter so i know thats not the problem.

I've opened up the entire wiring harness to find the issue and im so lost

My first question is about the switches on the handle bars. The small pin that grounds out on the bars I flied that down so i can run my clip ons and im wondering if that may be the issue here. Although the pin is making contact with the bars Im not entirely sure if that could cause the issue im having. I've checked all the grounds that i've followed on the wiring diagram and I can't seem to find the problem.

When i hook up the battery and turn the key absolutely nothing happens - All the wires from the ignition to the harness are completely fine and all the fuses are intact. ANY ideas for my next step? :'(

That's a locating pin not a grounding pin, you could pull it out of switch body
If you have no power you need to trace RED wire from battery to switch and BLACK wire from switch to fuse box
Green is ground

All the wires from the ignition to the harness are completely fine and all the fuses are intact.

If that was the case, you wouldn't have posted it would you?

What PJ says. Red wire is always live. Ignition switches red with black making black hot when ignition is on. Green is always ground.

I suugest you locate the plug connecting the ignition key to the loom and pull it. Take out the multimeter and see if the red wire is hot by grounding out via the meter.
clean plugs while you're there anyway

If not, problem is in the red wire between battery and ignition.
If so, hotwire black to red (with a spare wire or pliers) and see if you have power in the system.

If that works, you ignition key thing is dead. Replace.

Report findings and we'll help you further.

Ah yes you wise men I appreciate the help. So I hooked up the battery and shoved a little test light right off the red wire coming off the ignition and it lit up. I also touched the test light to the fuses and it lit up as well. Live yes indeed but still nothing is working off my switches. ? My horn/starter nothing happening there. My points were open as well and when i touched it with the test light i still got nothing. And yes the ignition was on as far as the switch from the handle bars but im not even sure if any of thats working. Ive double/triple/quadruple checked the wires coming from the switches going into the harness and Im 100% they're correct. I have a wiring diagram that ive become pretty familiar with and im still lost with this problem.

Should i take the handle bar switches off and investigate?

Again I appreciate the input. Id be damn lost without this forum -

Ignition switch has 3 positions, Off, On, Park
In Park you generally have taillight and nothing else
The wiring on back of switch is Red, Black, Brown, Brown/white tracer
Current flow when turned to On is Red to Black, black to fuse box
I'm 99% certain the brown is only live from fusebox back to switch then brown/white out, except in Park when red connects to brown/white
What other mods have you done?
100% stock bike is very difficult to mess up, even if your colour blind

Clip ons and a new set of points/condenser. Im going to pull the switches off tonight to see if something is wrong. Still a little lost as of why im not getting power to the points either. Shitty!

 

[renslow]

Any ideas why I get power to my ignition but nothing from my switches? I have power to my fuses when i hit them with a test light but im still not getting any reaction with points/headlight/starter/horn. Im getting power everywhere but my switches it seems like. Lose grounds or faulty grounds from both switches?

 

[cactus]

So non of the lights turns on too? I have a similar problem, the horn and starter wont work but everything else does, so my guess would be grounding on the handlebar, but then I wiggled the wiring inside the headlight bucket and it fired up so its possibly loose wiring in there.

 

[crazypj]

The switches will have a green wire for grounding if it's needed
your problems will either be under the tank where everything connects or at the housing junction where wires go in
Did you thread wires through bars or bodge a cut away into switch housing?

 

[renslow]

I drilled the housings out just enough for the wires to fit. Made sure it didnt slice anything and i smoothed down the housing so it wouldnt cut the wires when i clamped the switches. I'm out of ideas - when the rain stops ill try again

 

[crazypj]

In that case it has to be a connection under front of tank or inside headlight

 

[renslow]

I've checked all my grounds and i'm still stuck with the same problem. I pulled the bar switches off to see if any wires were ruined or stressed and everything looks fine.

I'm only running the speedo so I have all the indicator wires wrapped up -

I'm not getting power to my 'Tail' fuse because i havent mounted a bracket from my brake light/blinkers but i know that shouldn't stop power to everything else.

I don't get why my headlight doesn't work, my starter doesn't fire, nor am i getting any power to the contact breaker. I've checked the wiring from the condenser and from the coils and everything matches up. My points are open and im not getting and continuity what so ever.

I've exposed the entire harness to see if the previous owner has messed with it and everything looks fine. The wiring on these old twins are rather simple i'd just hate to give up and drop more money on the bike to have someone else fix it.

Electricity follows a path....You said the red wire to the ignition switch has power. When the switch is in the "On" position, does the black wire out of the switch have power? If not, you found the issue. From there it goes to light switches, kill switch, etc. From kill switch to points...

If you don;t have a least a test light, you can't trouble shoot....

Fuses having power on both sides mean fuses are good, but not any other connections.

Of course I have a test light! So I just checked to see if i get power running to the 'black' wire coming off the switch when everything is put to the 'on' position and it lights up exactly how it should.

But even when I put everything to 'Off' position it still lights up. No break in continuity or anything. If that even means anything at all.

?

Where does this leave me now? Hot damn thanks for the input I appreciate ya'll trying to help me solve this.

You need both of the black wires on right switch connected to main harness, they are not bridged internally
One is for lights, the other for ignition. I sounds like neither is connected.
I forget the colour it comes out to lights (brown or brown/white?) but the black comes back as black with white trace to coils
Pretty sure it isn't a ground issue

I will definitely look into this - Hopefully i'll be back with some good news. Thanks again

Pulled apart some more of the wiring and found some good ol' handy re-wire work. So from the picture with the wires coming in from
the left (I pulled the black wire coming from the horn off)

wires from the ignition>right handlebar switch>front stop switch>>>then the wires coming in from the right....voltage regulator<relay starter motor

Allllll spliced in one spot. Seems legit..

Is this correct? If so i plan on getting rid of that gob crap but I just want to see if this is all correct. Hate seeing janky work like this

Starting to lean towards purchasing an untouched harness off Ebay or something.

 

[renslow]

Ordered a wiring harness for a 360 - consider this post closed. I'll post again if i run into any problems but again i appreciate the help you guys. Saved me some money and a lot of time. Always in tune with this forum so i'll keep you guys posted;
