Who knows about CG eletrics ?

[X9-125-Evo]

Hello.

For last week i have been having problems with bulbs Blowing  2 indicators, main back light, 2x headlight bulbs blown and MELTED spedo light bulb  and flickering main headlights.

Picture of bike has it is, totally striped down trying to find Evey wire end to maybe find a bad earth?



so far bulbs have blown, and fuse next to battery blown, i replace the fuse, and a new battery fully charge, all going well, but flickering main lights, and indicators have mind of there own some times working something not, some time when turned on they just say lit and don't flash but start flashing when reved up.

Anyone know whats wrong with it ?

Regulator I would guess.

Its a  HONDA so I would agree regulator 90% of things that go wrong on a honda its usually that and its quite often goosed the battery before you notice

[X9-125-Evo]

had a look at the while the tank was off? there cheap to buy, but how can i test it ? the bike is supplying 14vs to the battery and is charging while riding. The Regulator as i found was in a protected rubber cover, and for 20yrs old was clean with no rust or dirt!  looked brand new.

Is there away to test, rather then say buy one, pop it on and find its not the Regulator ?

Thinking about it the battery was fine weeks ago then started discharging.

PS looked on ebay and foud a few, but diffrent years of Cg, must my Regulator that i buy be for a 1989 BRJ model ?

http://www.electrexworld.co.uk/pdfs/Troubleshooting-3P-PMG-&-RR.pdf try this to try and sort out problem

[X9-125-Evo]

thanks ill try it and iv book marked that page

Do the volts stop at 14v or do they continue to climb as the revs are increased? If the volts stop rising at 14 it is probably not the regulator.

[X9-125-Evo]

Hi

When i had the Volt meter on it, when revved the volts increased, ill have another go later and post results, iam sure they stooped at 13.5v. ill check later

[dididowell]

As I recall you were talking of doing some sort of mod to the headlight, And were warned against it. Did you do your mod, as this could well be the result you were warned of.

[X9-125-Evo]

no i didn't  do any mods to the bike as i wanted it to stay bog standed, i have only replaced the head light with a holegen equivalent of the current old bulb that is in the old bulb was a 35w old globe type bulb now have 35 halogen bulb, Same wattage, don't think that could done anything ?

[Dave Milnes]

Just fit a new regulator.

[X9-125-Evo]

I have got it on order cost ........      8.00     cheap! god the bike is easy to Fix and easy to work on,  so Far i have learned to strip it down, do valves, check pistons rings ( that was hard ) reassemble the whole engine even harder for a first timer, after dismal to find the pistons rings are necked, red drum brakes replacing, chain sprockets.

If i i wanted to do the valves on the x9 i would have taken me hrs, as you have all the plastic the only down side to a scooter like the x9 been enclosed unlike the CG.

thinking of keeping this along side my next bike, you know the feeling when u maintain and look after a bike and hard work on it you don't wan get rid of it .

The things i did  on the X9 like -Brakes - valves- belt - oil -  toke ages compered to the CG

They should make a scooter where the engine is very accessible to work on ? think they will one day ?

[julian]

I think everything is very accessable on the old skool scooters. The panels unclip from the side of the rear wheel and you can get to everything. Being two stroke also helped ot keep things simple.

[Big Ears]

Quite so.



 But the whole point of the original scooter concept was that it could be ridden wearing fancy day clothes, without getting covered in oil and muck.

HELLO

I have just fitted the regulator i ordered, turned on bike, and lights still flicker, indicators been AWOL. plugged the wires from the CG ( wires that plug into the battery ) into my volt meter, and revved it, volts it reads is 4.4v - 5.0v.

So the regulator hasn't solved the problem, iam baffled as to whats next to check ?

[Dave Milnes]

In that case the stator that sends the charge to the regulator is not doing so.
Check the connectors where the stator output wiring plugs into the loom, or the regulator input.

When you check the voltage, you do it across the battery terminals with everything connected up normally and the engine running.

Check for any master fuses on the starter relay (like the X9 has) or on any thinner wires going to the battery terminals.

What is the voltage measured across the disconnected battery. If the old regulator was allowing excess voltage, enough to blow bulbs, it could well have fried the battery cells too. The new regulator won't work as it cannot properly sense the battery load if it has dead cells. Can you borrow a known good battery?

[X9-125-Evo]

Hi Dave.

I have 3 battery and tried with them all.

ill see if i can check the stator, but iam due to be delivered a Honda CG engine tomorrow Off my mate who giving me it free .


These are my test results as of today done at 12:30 :

Bike off, CG Battery reads                                        13.30v
Bike ruining, CG battery reads                                   14.60v

CG Wires from loom plugged into volt meter rather then Battery, Idle speed no revs :    8.56v

indicators are annoying, once side flashes, but becomes awol when reved, other side just lit and no flash

starter relay

   does this have one, been kick start only.

[Dave Milnes]

Battery sound OK then as does the regulator.
What about all the earths particularly the main battery -ve lead?
Try measuring the voltage at the headlight or a sidelight and if less than 13V measure between the +ve wire at the light and the -ve battery terminal. If that is OK then the problem is earthing somewhere. Hence the poor flasher, as that works on resistance to ground.

[X9-125-Evo]

Just taken your advice and tested the side light ( 1 side light bulb 5w ) reading at idle is : 0.74v revved  Reads: 1.60v How i did it ( so you know if i did it correctly )  2 wires on the side light bulb + an - connected + to the + on the volt meter and - to the - on the volt meter.

[Dave Milnes]

OK so now test between the +ve on the bulb holder and the -ve battery terminal. If you now get 12V-ish, then you have a serious failure of the -ve battery grounding to the frame/engine.
You could do a resistance test (ohms) between the -ve wire at the bulb holder and the -ve battery terminal. It should be virtually zero.

[X9-125-Evo]

OK i'am back just did that test as you said    0.70v    +ve on the bulb holder and the -ve battery terminal

[Dave Milnes]

You did test it with the lights turned on?
If not try again. If the voltage reads 12V or more the fault is a dud ground from the battery -ve.
If it's still low (try a few +ve connections) and the battery -ve the same as between any two wires on a bulb holder it would seem the fault is not with 'ground' but with the +ve supply.
Where does the +ve power tap off the battery? If there is no starter solenoid being a kick start, there must be a point where all the fuses get their +ve feed from. Does the battery +ve lead go to any sort of terminal block or fuse block? Check the voltage there, and if it's dropped, there must be a break in the main battery lead.

[X9-125-Evo]

The + lead from battery goes throw a fuse 10amp ( that's not blown  ) then from there heads into the loom and leads up to pass under the tank and to the dash and lights. i can see no splits or tears along the loom, and its never been touched and its warped black thick tape.

yes when i did the test on the side lights i had all the lights on. I tried it with my brand new battery on and the old one, even fitted My Piaggio x9 12v 14hr battery to it. still no change

Iam totally at lost ends with this.

Volts have same reading on side lights and main lights .

There is an earth lead that comes out of the loom near the battery and is bolted to the frame, toke that off cleaned - but nothing.

[Big Ears]

Have you measured the voltage from the +ve terminal of the battery to various points on the frame (with the battery connected as normal)?

You should get the same reading as going across the battery. But I'm thinking that you have a high impedance somewhere on the -ve side of the battery. In other words a duff earth, caused by corrosion on a connection, or a rotted lead.
