adding an rpm meter to a cub

[BaMBiNo]

hi guys how do i connect a rpm meter to a cub ? i riding a spark135

 

 

thanks

[d0n]

i believe there are some aftermarket rpm meters (e.g. autogauge brand) which detects the rpm of the engine via a wire tapped to the sparkplug cable

[BaMBiNo]

hmmm any idea how to tap ?

[kiss29]

Its very easy.

Just tie the RPM cable around the spark plug cable three-turns.

The wire will be able to sense the spark plug firing each revolution and send a electrical signal to the RPM meter to display.

I think someone is selling such meter for $70 on SG Yahoo auction.

hi kiss29 must i cut off the core? like bare wire to wire connection or? i heard can

can sombong from one of the wire connection from bike cdi or something... anyone willing to share their experiance?

[StingRhea]

just coil round the wire round the spark plug coil. not the spark plug wire.

Do not cut your spark cable lar, u crazy or something.....afterward the bare copper wire will conduct sparks to your bike and to YOU .

 

Just twist the thin wire around the spark cable, it only serve as to receive magnetic pulses . Read up on your Physics textbook

I bought two pieces from this joker before. It works on my Vaspa and 125z.

Or else someone can do a MO for this item.

hi guys i just bought a rpm meter and i tried coiling the wire to the spark plug cable but cannot leh

btw i not using original cable i changed it to ngk red colour type

 

anyone got any idea as to how to make it work ?

 

btw someone pm me but i del off coz my pm box 100% mind if u msg me again sorry

[CarroTT]

[BaMBiNo]

the rpm meter to the spark plug cable? ok i will try that will post tonight

i tried already.... cannot...

i have afew pics

like tat, if touching the meter to the cable oso not reading........i no comment

 

try on another bike to check the meter is spoilt a not........ or u forgot to put in batteries. heheheheee

[BaMBiNo]

mine no batt wan leh

 

mine is tap to ignition and batt. i already found the wiring for everything but the place to tap for the signaling i donno where?

the coil is the black thing in the first pic?

the cable got 2 cores leh... one inner and one outer... the outer wan is red while the inner wan is white... from wad i see i htink its too thick for any signal to pass thru... should i try slicing the outer wan(red) and wrap 3 rounds round the inner core(white)??

[d0n]

how abt try coiling the wire frm the RPM meter ard the top tip of the sparkplug before u slot the sparkplug cable onto the spark plug?

[CarroTT]

dun u think its a waste to slice the spark cable ?

bo pian leh... u got any more suggestions?

i am out of ideas liao... i believe is the connection and not the meter spoil coz i try 2 meters still cannot. i will take a pic of the cable tip to show how thick the cable is.. hopefully b4 6pm

[CarroTT]

take so many pics of ur spark cable, but not one pictures of the rpm meter itself

[BaMBiNo]

the diameter for the ngk plug is 6mm diameter..

 

in total there are 2 red wires 2 black wires and one green wire.

the red one is for meter and light + point and 2 black is for meter and light - point

the green wire is for source point for rpm meter.

These rpm gauges must tap from the coil.

 

Autogauge gauges are designed for cars. Meaning that the gauge is designed to run on either 4 or 6 cylinder engines. There should be a selector on the side opposite the face of the meter.

i checked already they say must connect to a coil???
