Topic: CB 500 Four (1972?) Full Restoration

Cal I have full 12.8v at the small black solenoid wire on notch 1.

Unplugging the small black solenoid wire, from the harness side is the small black wire I have continuity to earth.

[MickB]

Ok, plugged headlight in some wires touched, headlight flashed on for a second and no power! Found blown fuse, things are moving ahead.

[MickB]

I have continuity on the Y/R from the solenoid to the starter button when the button is depressed

[MickB]

I've got the idiot lights working - oil pressure, neutral and indicator.

Right front indicator flashes, rear doesn't flash, I think the rear maybe an earth problem.

Left flasher switch lights up both R and L front indicators? I think it's an issue with the switch, because if I back the switch off a fraction the L front indicator works, rear flasher doesn't maybe earth?

Foot brake light works.

Still no luck with the starter button.

Brand new loom and switches

[MickB]

I get continuity when I depress the starter button?

How do I insert a photo from a Mac? When I hit the Insert Image icon all I get is ??

Can anyone help?

Well back after moving bedroom furniture, ripping up carpet for 3 bedrooms, landing and stairs. Visitors over the weekend, carpet layers on Monday, work got in the way also!

Cal your suggestion worked, plugged the Gr/ R wire into earth, pressed starter and it spins over.

After testing continuity the rear blinker mount (bought from Z1) doesn't ground. I removed the earth and ran it through the blinker stem and fixed it to the bulb housing screw, now I have earth.





I now have the horn, brake, rear light, starter working, the R blinker working and 3 idiot lights working correctly.  But when I switch the L blinker on the R blinker comes on???

Left switch



I also still have 5 wires coming from the L switch control I can't find where to plug into? Br/W, Br/R (is this power or earth?), light blue, light Blue/ W and a dirty Yellow or is it orange?



Hi/ Lo beam switch, light green on right is horn.

Mick,
I just thought of the reason for this.  Could it be that it's because you're in Australia and the southern hemisphere that everything works upside down/backwards? 

[MickB]

Thanks for the correct way, and the obvious upside down theory, why didn't I think of that!
That's why Jared Hayne and the 49'ers is turning them inside out with his unorthodox upside down style.

[MickB]

Good news is I have the headlight Lo/ Hi  (including Hi beam idiot light)and taillight all working correctly.

Mick - in the LH switch, you've got the L and R indicator wires backwards.

Turn L - Orange/White (dingy Yellow wire in your unit)
Turn R - Blue/White

The "Brown" wires are always carrying current, for instance, Br/Red is headlight power from the fuse.

Cal I see in the paper I've incorrectly written the L and R wiring colours, I've put them down on the wrong side, they are correct eg Orange is on the left side etc.

New clutch adjuster from CMSNL, 3 days from Holland!

Indicators aargh!

This is the flasher unit with only 2 spades, the wiring diagram shows 3 spades? Could this be the problem? If I take the Br/ Dark Blue wire and move it over to the Left Orange side the left indicator works fine,

But if I use the R Light Blue indicator switch the Left indicator goes and visa versa if I move the Br/ Dark Blue to the R side the

2 ire flasher just don't use the green wire, common on US 3 wire seems to be European model, the blue/white and orange/white are for the front running lights used in US along with twin filament bulbs and fittings if you have only single wire type just don't connect them

[RAFster122s]

Front markers from factory used two wires with ground through the metal body of flasher assembly/stalk/fork ears/forks/frame for ground path.
Aftermarket need the ground wire to function properly,  normally.
The rears were usually just a turn signal so, they are one wire with ground in same manner as front.

Thanks boys but I think the issue is with having a 550 control. The 500 had only 3 wires coming from the indicator switch Grey, Orange and Sky Blue whereas the control I have has 6 wires (as best I can see) for the indicator and this is where in stumped.







Some wires I presume need to be either joined or discarded.

BJ any ideas? You mentioned a way to get a 550 switch work with the 500.

[MickB]

I put an earth wire in the front left indicator to take away the problem in case it was caused by a bad earth, it didn't work.

I turn on the left indicator and the right one comes on?!

I presume there must be a cross over in the wiring occurring somewhere to cause this?

I have 5 wires left from the LH Control. Could there be a cross over occurring in the switch itself?

Do some wires in the switch need to be cut out in order to replicate the 500 switch which only had 3 wires.

Any thoughts?

I'm stumped!

[bryanj]

The blue/white and the orange/white you leave unconnected, you should then have a grey, orange and blue, Orange to an indicator doubler in headlamp same with orange, grey is from flasher relay.

what is the sixth colour?

[MickB]

BJ thanks for your reply, attached are photos that show the exact state of play.

Trust you can advise which wrist to slash.

Photo shows wiring left over from left switch control.

With the right indicator working with power from the Br/ Dark Blue wire, What powers the left indicator? If I put the Br/ Dark Blue wire over to the Orange left plug the left indicator works and not the right. It's like I'm missing the left indicator power wire.

Is or should the power coming from Blue (shows as Light Blue on the photo) wire from the control switch?

When I use the left indicator the right indicator cons on instead, could that be caused by a bad earth?

[bryanj]

Brown/blue has nothing to do with the indicators disconnect it and insulate it, same with qrange/white and blue/white.

Blue from switch should connect to a multi connector with:-

Front indicataor
Idiot light
loom to rear

Same for orange

Grey goes to grey from indicator can

That should work OK, perhaps the brown/blue went the the 'orrible buzzer?

[MickB]

Bingo! You beauty, it's a goer.

BJ your blood's worth bottling!

[MickB]

BJ I was just thinking about how simple the solution was, blue, orange and grey. Exactly the same as the book, now why didn't I think of that? Dur!

I think I'll cut and paste your solution to Tips and Tricks so some other Neanderthal can make life easier for himself.

[bryanj]

No problem, it just takes a bit more thinking about when its different bikes, different countries and not in front of you!!

[MickB]

Mick - in the LH switch, you've got the L and R indicator wires backwards.

Turn L - Orange/White (dingy Yellow wire in your unit)
Turn R - Blue/White

The "Brown" wires are always carrying current, for instance, Br/Red is headlight power from the fuse.

Cal you came close but no cigar.

Replaced the cheap rubbish Asian fork boots with genuine Honda, a big difference in rubber thickness.

Rubbish boots, theses boots split and perished just sitting on the forks without and riding.



New boots located with holes pointing down and facing the rear.



Peeled off all the lacquer (POR Lacquer is rubbish, loses the shine and makes the alloy dark) from the forks and polished again.
