CG 125 electrics

[pdg]

Anyone got a link to a wiring diagram? I'll trace it all and draw my own if it comes to it, but it's raining.

2004 CG125 (electric start only model).

Everything I've found on Google so far appears to be for kick only models so is quite different...

Its in foreign money but easy enough to follow

Ta muchly, closer than any I managed to find as yet.

Still doesn't seem quite right - there's what is listed on cmsnl as a "thermo switch" present on the bike that doesn't appear on the diagram that I'm struggling with (struggling in this instance = I saw it, found it on the parts list and said hmm, and haven't investigated further due to aforementioned rain).

The electrics seem minimally messed with, however part of the reason for looking is previous owner expressed difficulty in getting the indicators working correctly...

I like the porfeshinal wiring on the flasher relay

Fowlers fiche lists a thermo switch too
but why would a cg125 need a thermo switch?
its air cooled and has no carb heater I can see.

I'm wondering if someone has confused it with with the diode
used in the starter circuit which basically stops the neutral light coming on when you pull the clutch

Edit
Checking the fiche again I see It shares this part with the XR125L which has a carb heater element presumably controlled by
the thermo switch in question, so in the case of the CG125 its a redundant part unless it has heated carb.

Mechanical indicator relays rely on a bimetal strip and heat to make it switch thus 'thermo'....

Yeah, original flasher relay was a 3 wire too...

And, apart from the fact that I've forgotten how to embed images, I haz pics.

Thermomabob next to the diode, and electrocuted carbamatutor.

Could be worse, could be better.

Wht you are looking at on that diagram for the indicator relay is the 'Interrupter Da Embreagem' (excuse my portugese....)

What colour are the wires to your fluttering relay?

Yellow with red trace
Blue with white trace
Green with red trace
Black with brown trace


Edit: it's in the pic a few posts up next to the orange flasher unit.

Y is yellow
L is blue

At this point Im really not finding anything in that wiring diagram that fits.

Presumably if four wires it's a relay, trigger, earth, triggered input, triggered output.

If fluttering the only thing I think of is marginal amps...

Red on green is usually neutral light on a honda. Red on yellow is usually starter trigger.

This probably isn't helpful...

First thought is it's a starter relay used to trigger the solenoid which incorporates a neutral safety lockout. If it is, I'd expect the red on yellow to be live when the starter is pressed and the red on green to be earthed when the bike is in neutral.

That leaves two other wires, black is usually a switched live feed of some sort on a honda so I'd guess the white on blue goes to the solenoid.

Or I could be wrong.

Aaaaaaalrighty then.

I decased it. It's a normally closed relay.

I also traced wiring.

Yellow/red and green/red are parallel with the starter solenoid coil.

Black/brown is ignition switched live.

Blue/white - goes to the headlight dip switch...


So - you turn on the key and press the starter button, this energises the starter solenoid coil and also the coil within this ex-mystery relay.

There is no light switch on this bike, just a dip switch. Lights are permanently on with the ignition.





It turns off the headlight when you press the starter.





It would appear that is done to reduce the load on the battery during cranking. I can think of no other reason (I suppose it may have a secondary function of ensuring the headlight bulb doesn't see a low voltage).


Other diagnosis - the fluttering was due to a poor contact in the harness connector from the starter button. It also wasn't cranking because the starter solenoid was stuck (I hit it on the floor and freed it up, shall likely replace).

Other fixes - The orange flasher unit had water in and was stuck, I stole the 3 wire flasher off the scrap chinky scoot and a chunk of the harness (to obtain the connector), crimped that in and indicators now function correctly. They're broken physically, but they work electrically (shall replace).


Still got a to-do list, but it's getting shorter.

To be pedantic, I'd say Light green/red is neutral light onna nonda

Well, it's been all day and it's still working - so I'm declaring it temporarily fixed.

That part at least...

Ok, this is going to turn into a show and tell, I found another indicator related electrical problem - in fact, it's highly likely that this particular thing is the root cause of all of it and it's been waiting since the bike was built 20 years ago...

As a taster, I shall drop two pairs of words on you:

Wiring loom.

Manufacturing defect.
