VOLTAGE STABILIZER for Motorcycles

[danvincent999]

---

share ko lang. i know some has already read this in mcp. i got this from hfric.ning.com (forum for honda bike owners) ts got it from mcp. it's diy voltage stabilizer. i'm not an electrical engineer so i can't go into details but benefits are good electric current on your mc so good fuel burning thus gives you more mileage for your gas. here's what i did.

i bought 2pcs each 25V 4,700uf & 3,300uf capacitors; fuse holder; 6Amp fuse; for my case i used a 6 pin double pole switch (its up to you how you want it connected); 3V LED; 1pc resistor; 9V battery if you prefer t use one and 1m wire. ofcourse you will need a soldering iron and lead and if you prefer to put a casing on it then look for a suitable one. in my case, i used a calling card case. you can use a pcb board or not, depends on how you want to construct it.

the capacitors i used are the electrolytic type (this type is polarized) and what you need to do is to connect them parallel to each other,that means negative to negative and positive to positive (you can use a pcb board, in my case i just connected them directly. saves a lot of space). then connect the fuse on the positive side of the connection. if you prefer to use a LED then connect the LED to the fuse. then i tapped it to the center pair of a 6-pin double pole switch. then the 9V will be connected to the left side pair and the connection to the mc battery is connected to the right side pair. you can interchange them though, which one on the left and which one on the right. as long as the connection from the capacitors stays at the middle pair.then you tap it directly to your mc battery, the positive to the positive and the negative to the negative. and viola, your own voltage stabilizer. i've just installed mine this afternoon and when i drove my mc, i felt immediately the difference. the engine is more smooth and the throttle response is much better. this is the original diagram but what i made is already an edited version of this diagram. diskarte na nimo unsaon nimo paghimo sa imo version.

just imagine these are the capacitors...

(in layman's terms)

2. tama si sir roadstar. 12V lang po ang rating ng battery. but its nominal voltage is 12.63V +- adjustments on temperature. yun pong voltage na nakalagay sa electrolytic capacitor ay ang maximum voltage nya. under normal conditions, walang pinagkaiba ang 16V sa 50V cap. but in case nasira ang regulator mo at umakyat sa 20V ang output voltage nya, puputok ang 16V cap kasi lagpas na sa maximum nya, pero ok pa rin ang 50V cap.

3. sa pros and cons naman. i don't see any con, and the fact na it can stabilize voltage is good enough for me and i don't think anyone would argue that. there is much skepticism about the other benefits though.

a.) ignition - if you are using a DC-CDI, it may or may not help. It can act as a reservoir for the CDI so that the capacitor in the CDI can charge quicker. If it maximizes the DC-CDI's function, it can then provide better ignition, which also helps with cold starts. If your electricals are in tip-top shape, it won't make much of a difference since your CDI can already acquire the power it needs from the battery. But since batteries do tend to degrade over time, having caps may help you extend the time before you get ignition problems and get more out of your battery before you would need to replace it.

-if you have an AC-CDI, it would do absolutely nothing for ignition as the AC-CDI gets its power from the stator and not from the battery.

b. starter - it may provide additional power to the starter but it is quite insignificant with only 40,000uF (0.04F) of capacitance. considering that 1F = 1Ampere-Second/Volt and let's say that you get a voltage drop of 4V for 5 seconds. The capacitor can only contribute 0.032A to the 60A-80A that the starter motor needs. If you have a 20F EDL capacitor (no circuitry involved) with the same scenario, you get 16A.

corrections are welcome po, if i got things wrong.

above is for underbone motorcycles...

this one is for 150cc and up motorcycles...

how to do it?
Just 4 pcs of 10,000uF, 25VDC Capacitor installed parallel to the battery
10,000uF 25VDC cap cost 50 pesos in davao... we have to check the prices here

Parts list:
4 pcs. 10,000uF 25VDC Electrolytic Capacitors
1 meter automotive wire, #10 or 12 AWG, red (para sa + terminal)
1 meter automotive wire, #10 or 12 AWG, green (para sa - terminal... wala kasi green sa binilhan ko kaya blue ginamit ko. hehehe)
2 pcs. ring terminals (estimate nyo lng basta kasya sa battery terminals nyo)
electrical tape

Tools:
Soldering Iron
Lead for soldering iron

YOU WONT REGRET PUTTING THIS IN UR BIKE!!! believe me!!!

[dookie3283]

nice idea sir...try sd ni nko nya...lol

[jaze23]

YOU WONT REGRET PUTTING THIS IN UR BIKE!!! believe me!!!

Dan, pwede ni nko gamiton sa ako wave100?
using 4pcs. 10,000uf 25v caps?

[rsvlt]

its much better to vary the capacitance of the capacitor so that your vs is more flexible at regulating and providing current... vs user here. DIY ra pd.

[danvincent999]

sakto si RSVLT!!! hehehe...
it would be good if mag vary ang capacitors...
ang sa akoa lang, 25,000uf @ 25v 4 kbook is ok na ky dagko mn na capacitor.
as wat ive read sa MCP, the bigger the capacitor the better.
naa gani ga butang og isa ra kbook, pero 50,000uf @ 50v asa ka ana! hahaha!
mura tawn og kumo ka dako. hehehe...

@ DOOKIE

Pwede kaayo sir! actualy ang migo na nag push nko ani ky nka WAVE 100 pd. black wave 100 iyang motor nka VS na, DIY pd.

pag taod nko ani sa akng motor na amaze ko ky quick start, murag kusog kaayo og koryente ang starter nya na pino ang minor. limpyo og dagan ang motor.

inig on nko sa tnan lights, dli mag blink2 akng batery meter. nindot jd ni cya na MODS...
mo gasto ramo ani og 250 - 400 pesos

try ang numbers sa capacitor sa ibabaw.. sa first post nko.. pang underbone to..
pwede ra kaayo ang WAVE 100 sir.. migo nko nka wave 100 nka ingon ani na..
pero kanang diagram sa first post sunda.. ayaw ning naa sa ubos ky sa 150cc pa taas mna.

Ok, so i would buy 2pcs 4,700uf & 2pcs 3,300uf capacitors
and connect them parallel to each other then parallel to the battery?
ok na na?
gusto ko mas simple lng...
