It takes just one hand for you to turn to reserve. an indicator that you are about to enter reserve is when your RPM suddenly drops, and your bike starts to splutter from the sudden increase in AFR (air-fuel ratio).

 

when that happens, you can use your simply turn the tap while you are still going.

Thanks a lot bruders!!! This is really valuable information.

U're welcome. But spai_duhz's method above is highly not recommended, esp for newbies. His' is 1 of those 'the following stunt u're abt to see is performed by trained professionals, pls do not try it at home' type. Meet him and u'll get wat I mean

ALARM sensititivy Update III

 

AFter yesterday grounding, i found out that my alarm is still over sensitive... it keep sounding in the middle of the nite till i cannot take it, but have to disarm it.

 

Just now, this what i did... I snip the green cable and i cut off the two "ear" of the alarm module and tape it on the side flaring. i will con't to test it and update u guys later....

 

 

stay tune

[Nemesis]

Wah seh, type so much until finger numb

 

:D

 

lindavw, can provide a photo of the sensor and maybe let me know the concept of the sensor as in how it is activated to trigger the main unit?

 

:D

 

It might be the module itself.... we never mount the module to any secure place....

[Nemesis]

Let me know when u going to AGL to replace ur hub n sprocket. Wanna change both my sprockets n chain. Any day is fine as long as the next day is not a sch day. But no need to make any special accomodation for me lah

 

too late, he is inside already when i post this msg... i going in now also... :cheer:

Alarm sensitivity UPDATE II

 

Just now, I have R&D on two bikes. This is the result. UG2 and UG3

 

UG3, onli connect the earth cable while,

UG2's green wire had been snipped into two pcs. (NO TRIMMING)

 

Result (I travel and zoom past these two bike...)

 

UG3 alarm went off

 

UG2 alarm never went off....

 

Conclusion.....

 

The earth cable is optional. My bike is config the same as the above UG3 test bike.. still when bike went past, the alarm went off...

 

 

how to do....

 

Sniped the green wire in the center. from there u get 2 pcs of green wires... one pcs, tap it to the chassis of the bike. 2nd pcs, just leave it as it is.

 

Neverthe less, we can wait for feeback from WEICONG. I will con't to test it. most likely confirmation will be out by monday.

 

Bro, after cutting the green wire it seen to be less sensitive as in the impact near my bike wont trigger the alarm so easily but whenever there is a plane flying pass my alarm will still trigger and thunder sound will still trigger my alarm..

any more advise that i can try to adjust ??

 

Cheers,

Project to change 6 holes wheel hub to 4 holes wheel hub is a

TOTAL FAILURE!!!!!!!!

.....It can be done only if u change the rim also

 

:cry: :cry:

[SuVespa]

Now I wonder whether can return the wheel hub...boooohoohoohoooo

:cry: :cry: :cry:

Bro, Grounding just helps to reduce one possibility. As it is clearly tested that it is not the main cause of your problem, you should look at other settings that can be done to rectify the problem.

no problem bro... i will still con't to ground it cause "i see no harm to it" hahahaha. please con't to give suggest on how i can reduce the sensitivity.

:cry: :cry:

 

By rite it can fit one leh. can explain in detail y cannot fix???

u bought the 4 hole sprocket??? maybe we can try to DIY something to make it fit...

When there is no solid reference point for the voltage, a +12v might not be a +12v in the alarm. In a floating ground situation, the shock sensor will not be a problem but the input to the controller chip that is connected to the sensor might become more/less sensitive to voltage fluctuations.

 

 

Depending on what kind of diode you are talking about, but diode generally are not used to stabilize current. They are used to guide electrons to the path that you want it to go, or block electrons to paths that you do not want it to go to. Sensitivity to the controller need not be less sensitive, it can be either normal, more sensitive or less sensitive, depending on the floating reference level at the point in time.

 

 

That is just an example of reducing the sensitivity, if the sensor is operating in the way you described. Spy 2-way uses a potentiometer to change the sensitivity level of the shock sensor.

 

 

 

As with most china made alarms, I noticed that the same wiring diagram is being used across different brands of alarms. I bet if we were to compare your manual and mine, we will see the same wiring diagram on both. The black wire should be going into the ground rail of the alarm's power supply. Unless that black wire is totally isolated from any connections in the PCB, then it makes no sense to connect that black wire as it goes to no where. Erratic as in unstable brightness or not turning on at all. Alarm sounding off for no particular reason can happen but it will be a random kind of symptom.

 

 

 

 

The alarm system does not solely run on 12vdc, most likely the RF components are running on 3vdc. There might be more than 1 voltage logic in the system, you really have to take out the main PCB to check on that. My SPY 2-way has at least 2 voltage logic levels in it. One is 12vdc and another is 3vdc. I am not sure if there is a 5vdc for the other ICs involved as I did not check on that.

 

I am suggesting ground as a possible cause and not the only cause.

 

 

We do not need a particular impact force to activate an unstable system, any induction (interference) can cause the alarm to trigger.

 

A controller is a digital device, it is either a 1 or 0 at its inputs. Outputs from a sensor can be analog, usually goes through an amplifying circuit and converted to digital logics for the controller to understand.

 

I have not seen the type of shock sensor used in the RD008, Spy is using this http://i338.photobucket.com/albums/n426/joajas/DSC01871-1.jpg

 

It is using electromagnetism as a trigger.

 

 

So far the systems that I have been involved in designing, uses 12vdc, 5vdc and 230vac as power source. Each has its own reference points which as eventually brought together to a common reference that is the Earth point. In the initial stage of design, during testing, one of the ground points of the trigger portion was not brought to the common ground. That cause hell lot of a problem, as the system would trigger for no reason. A light touch to the trigger contacts also cause the system to go into alarm mode. We spent hours troubleshooting, and found a ground point not brought to the common ground. After bringing this point to common, the system became very stable.

 

One final point and I hope we can close this discussion as it is getting out of topic. When we connect a +12v to the alarm, we need to give it a 0v ground aka return path (battery -ve terminal). The alarm is designed to work in a max +15v potential difference environment. If we do not give it a solid 0v ground (return path), the ground point will be floating. It can be 0v, +?v, or -?v caused by many possible reasons, one being induction.

 

For example, at a certain point in time a if a -2v develops at the ground point for whatever reason. With the engine off, battery +ve usually has +12.8v. +12.8v to -2v there will be a total of +14.8v potential difference in the system. Turn on the engine and rev, we can get over +13v. Coupled with the -2v at ground point, we could be over the voltage limit of the design, this can potentially damage the components.

 

If instead of -2v, we have a +2v at ground point, when engine is off, we could be getting only +10.8v of potential difference in the system. After voltage drops at various points in the system, some components might not be getting enough voltage to drive it, causing the whole system to be unstable.

 

This might not be the cause of the problem that everyone is facing, but it can be a problem given the right conditions. Simply saying,, it is a time bomb waiting to explode.

 

Giving the system a solid ground reference, we can eliminate this probable issue in future and ensure that the alarm functions reliably.

:cheers:

 

http://en.wikipedia.org/wiki/Ground_(electricity)

Taken from the URL above:

Voltage is a differential quantity, which appears between two points having some electrical potentials. To measure the voltage of a single point, a reference point must be selected to measure against. This common reference point is called ground and considered to have zero voltage. This signal ground may or may not actually be connected to a power ground. A system where the system ground is not actually connected to another circuit or to earth (though there may still be AC coupling) is often referred to as a floating ground.

Hmmm... I understand wat u r trying to say...

But now grounding is not the issue anymore so think of other possibilities... typing a paragraph so long will only confuse pple more hahahahahahaha

 

I didnt take a pic of the sensor the other time when i autopsy the alarm. but it does run on a spring n snap disc. Unless another GP wan to let me try lor lol.

[joajas]

I have read some of the manuals of the more expensive alarms, and they all suggest securely strapping/ double side taping the main unit to the bike.

 

Maybe in addition to that you can use some cotton wool to support the green loop wire to the frame and hopefully it can help absorb some of the vibrations.

 

The best is to find out how the sensor works and from there try to find a solution to the problem.

 

Right now i can only guess how the sensor works from bits of info here and there.

:lol: End up all blur. :D

[lindavw]

don't do that please! later you end up staying at home and play psp only. =x

 

 

can la maybe i sit in shopping centre or macdonalds got another pretty lady oso playing psp then end up linking up n playing 2 players wait later become my gf u oso dunno wat . muahahahaha.

Does it work like, when there is vibration, it will cause the disc to come into contact with some contact point there for triggering the alarm?

 

Could it be the spring being too soft, allowing the disc to touch the contact points too easily?

in some sense it does work like that. the spring stiffness will play a huge part in the sensitivity.

For those brethen

 

who still consider whether want to go for the pagoh trip, here some update.... (I attended the briefing last nite)

 

1) there will be a safety car following behind.

2) any minor problem to the bike will be rectifty on the spot. etc, tire kenna nail or so... engine overheat, not euff petrol

3) Any Major problem will be tow back to singapore... no hassle, all arrangment have being made.

4) There will be a medic following there.

5) marker and sweeper had being deploy. so no one will be left behind.

 

I have further arrange a workshop to do a pre-ride check on sat before the ride.

 

So guy. what u waiting for ??? since all issue have being covered. if you still have any worried... Feel free to contact me at 82888807

 

This trip is to build up confidence in ur bike and build up ur on the road exp. Once we overcome this trip, we will be prepare for the next trip to cameron highland. once it have been overcome... the next trip will be thailand.

 

 

I need the confirm pple who will be going as to arrange the pre-ride check.

Is the green loop part of the spring assembly?

 

what happens when the green wire is totally remove?

 

Assuming that the green loop wire works as a kind of weight to amplify vibrations by works of physics. Will it be possible to totally remove the green wire to allow the spring and snap disc to solely work on its own?

guys .. sorry to distract you away from the alarm cabling and electrical wiring dillemma..

 

i just need to ask whats a guarantor..?

 

sorry for another stupid question from a noob..

A person. so that should you 1 day run away, the bike shop got another person to look up for to pay up the money you own.

[Roadrunner71]

whats a guarantor..?

A person who gives a guarantee that u'll service ur loan without fail till it's fully paid up. If u default on ur payment, then ur guarantor is legally bound by law to pay up for u instead.

 

So dun suka-suka be somebody's guarantor hor!
