Title: CB360 Wiring question
Post by: Craizeehair on May 09, 2024, 08:48:19 PM: I’ve started to connect things back up on my 360 and I thought that I had taken plenty of notes and pictures but I am a little stumped as I actually didn’t take enough.

In the wire cluster that sits by the fuel tank, I have one spare wire, there doesn’t seem to be anywhere for it to connect?

I also have two spare wires branching off the main harness near the front off the bike.

I’ve looked at what needs to go back on the bike and I can’t see what these wires would be for, could they be spares and not used? I find it strange that I didn’t get a picture or note it down somewhere but this is my first ever attempt and I have no experience so could easily have missed it, any help would be greatly appreciated. I’ve had a good look at the pics that I did take and it does look as though the two wires from the harness could be unused, I can just see one poking through that could be it and it does look a bit weathered, as if it maybe wasn’t connected and covered?

Maybe I didn’t notice the one in the cluster if I started unplugging wires it could have gone unnoticed?

It’s a 1974 with front drum brake if that makes any difference.

Any thoughts???

Post by: Bryanj on May 09, 2024, 08:55:23 PM: This is just a guess but the two at the front could go to the switch on the clutch lever so it will start in gear if you pull the clutch, not sure about the single one that looks to be same colour.
Have you got a wiring diagram?

Post by: Craizeehair on May 09, 2024, 09:12:52 PM: I have the shop manual so I can have a look in there to confuse myself.

Post by: AndyD on May 10, 2024, 09:44:42 AM: I think that light green / red is used for neutral switch / light on the CJ models so maybe that somehow?
I also seem to remember that there were one or two unused wires somewhere on the CJ loom but can't recall where.

Cheers,
Andy

Post by: Craizeehair on May 10, 2024, 11:29:02 AM: Thanks all, I will have to give it a good looking at over the weekend, along with a good dose of head scratching. I was hoping someone would say that they are surplus to requirement, not needed, unused and ignore them
Title: Re: CB360 Wiring question
Post by: andy120t on May 10, 2024, 02:33:22 PM: Colour wiring diagrams online - red/green looks like the neutral indicator. Is the other red/white? Harder to spot but maybe the indicator /flasher unit.

Post by: ozzybud on May 10, 2024, 03:11:08 PM: red/green is the clutch lever switch.
light green /red is the neutral light wire

Thank you, I can’t see where to connect them but that’s now a problem for the weekend. I wasn’t ready for this to stump me but it has… well and truly!

Post by: McCabe-Thiele (Ted) on May 10, 2024, 04:28:14 PM: The clutch switch was missing on my 400 but found one on ebay at sensible money - might be the same part?
Like this one might be yours is different though.

Post by: Craizeehair on May 10, 2024, 04:30:52 PM: You know what Ted, that could make sense as there definitely wasn’t one when I dismantled the bike, has a brake switch that looks jut like that though.

Off to get the parts manual!
Title: Re: CB360 Wiring question
Post by: McCabe-Thiele (Ted) on May 10, 2024, 04:33:35 PM: To fit them you just remove the lever & feed it in - it has a slot that slides into the lever bracket.

Mine fitted but I had to file the end pin down very slightly to get it to work properly.

The wiring colours were different but easy to see how it connected - only two wires!
Title: Re: CB360 Wiring question
Post by: Craizeehair on May 10, 2024, 04:45:06 PM: Just had a real quick look before we get ready to go out and it seems as though these early bikes might not have had a clutch switch.

There’s also a brown wire and a green and red wire both free and not connected in the headlight bucket and after a really quick look at the wiring diagram I think these may not be connected to anything either, could be pains over if I’m lucky???

Will have a few hours to muddle through something tomorrow, thanks for all the input, much appreciated.
Title: Re: CB360 Wiring question
Post by: Bryanj on May 10, 2024, 04:49:54 PM: Brown wire goes to the small bulb in headlight in uk which is not fitted in us, unfortunately it is a requirement to have an "obgliatory" light in uk and would fail mot if not there plus if you got a knowlegable plod( both words in one sentence) it could be an offence.
Depending on light size there are plenty of units out there.

Green and red may be neutral switch to idiot light wire

Post by: McCabe-Thiele (Ted) on May 10, 2024, 05:04:20 PM: The 360 ones on eBay look quite different.
Title: Re: CB360 Wiring question
Post by: Craizeehair on May 10, 2024, 05:06:25 PM: Thanks Bryan, I can see that brown wire now on the UK wiring diagram, makes sense even to me.
Title: Re: CB360 Wiring question
Post by: ozzybud on May 10, 2024, 05:10:13 PM: The light green/ red needs to find its way into the headlight bucket and plug into the gauge feed wires. It travels from the switch under the left side cover. Terminating at the bulb@ the neutral light.
Title: Re: CB360 Wiring question
Post by: cbxman on May 11, 2024, 09:57:35 AM: Clutch lever switch came with a diode as well in the CB360T, which has only arrived here from imports.

The UK had the 360G version, which does not have a mount point for the clutch switch. It does have the spare wires though and no diode.

I bought a clutch switch when I found the wires in my bike and I had a diode from a spare CB550 harness, but when I found there was no hole for the switch and checked the diagrams....No clutch switch....so your spare wires are just that...

Relax,

Jerry

Post by: Bryanj on May 11, 2024, 10:24:40 AM: Is this not a drum braked 360 or am i remembering wrong(getting more common!) If so it would be a us import and probably have the switch etc.
Easy to tell, look if there is a hole in the flat part close to where the lever pivots, if it is a drum there will be similar on brake side
Title: Re: CB360 Wiring question
Post by: Craizeehair on May 11, 2024, 10:58:44 AM: Correct Bryan, this is a drum brake USA version. I’m hoping to get a chance to get back to it soon but the MIL is round this morning and although to me that seems like the absolute best time to lose myself in the shed, Mrs C isn’t of the same opinion!
Title: Re: CB360 Wiring question
Post by: Bryanj on May 11, 2024, 11:52:22 AM: In that case it should have the clutch switch and brake light switch which are the same except wire colours and only you will see them, if you have problems locating them try the 125 single with drum brake
Title: Re: CB360 Wiring question
Post by: Bryanj on May 11, 2024, 12:01:33 PM: Just for you cos i was bored, motorcycle products with SKU: 006389 and look at attached screen shot.
Check if you need anything else to cut down post costs, i have bought several parts from them with no problems
Title: Re: CB360 Wiring question
Post by: Craizeehair on May 11, 2024, 03:03:36 PM: That’s very good of you, many thanks.

So to confirm, this will work as the clutch switch, just ignore the wiring colour difference and fit accordingly?
Title: Re: CB360 Wiring question
Post by: Bryanj on May 11, 2024, 07:42:42 PM: Correct
Title: Re: CB360 Wiring question
Post by: Craizeehair on May 15, 2024, 10:32:28 PM: A quick question for those in the know please?

I’ve got the wiring harness back on the bike and all the electrical components are now connected again.

Does anyone know if this bike will have daytime running lights? When I got the bike, the headlight wouldn’t work on low beam. I’ve stripped and cleaned the switch gear and now the low beam works but the front two indicators come on with a permanent low light. I initially thought that I had got something wrong but a quick check looks ok. I don’t want to start chasing a problem that isn’t there. From what I can see online, it does seem as though they could be?

Post by: Bryanj on May 16, 2024, 08:19:46 AM: Yes it would have, sconnect th orange with white trace and light blue with white tace in the headlamp as they aint legal in UK. Just remember you need a 5/21 bulb in front indicator same as rear light

Thanks again Bryan, much appreciated.

I know it’s 101 stuff but you’re saying I need to change the current bulbs to the 5/21 when I disconnect the DLR?

Post by: Bryanj on May 16, 2024, 12:45:53 PM: Nope, thats what they should have in them unless you have fitted UK blinker heads

Gotcha, thanks.

Post by: Craizeehair on May 16, 2024, 06:56:40 PM: DLR disconnected and all good now. Thanks for the help.
