Water temp installation

[gilos]

hello guys,

need some help here...
i tried to wire up everything but it seems that the meter doesn't get any signal from the water temp sensor :(

what i did..
1. tap ciggie lighter wire and connect to (+)
2. tap ciggie lighter ground wire to (-)
3. wire up the sensor
4. ground meter body to dashboard metal frame

when i turn key to ON, needle goes up a little bit....means power ok(i think...)
then i try to heat the sensor with my lighter... the needle does not move

anybody can help?appreciate it...thanks :)

hi there.

Many possibilities. Firstly the lighter flame is in excess of 120celcius (max on ya gauge) use hot water.

 

[gilos]

it didnt max the gauge...needle didn't even move.. :(
maybe i'm confused here...thanks anyway :)
any other possibilities?? :unsure:

maybe ur sender (sensor)unit not ground .eg. car engine, body ground.

just my 2cent

 

[gilos]

can i just tap ciggie lighter ground wire(black color) to ground the sensor unit??
is this correct?

or i have to ground it at the same point as engine ground?

 

[limau]

yeah ,just tab the cigar lighter ground wire will do the trick.

 

[phat7]

simply find any unpaited nut/screw on the car body should act as a good grounding point

okie guys...solved the problems hehee :D

sensor didn't ground properly...my bad...heheh
wire sensor and ground wire touching...causing short circuit(i think) and then needle shoots up to max(120degrees)..lucky the gauge didnt spoil.. :P

then ground it again properly...heat it with my lighter and needle steadily rise to about 80-90degrees...woohoo..

thanks guys :lol:

u need use hot water to test la...and ur temp sensor will sense the temp slowly ma..... ;)

hmm..now i need to find an adapter in between the hose to screw in my sensor...
anybody know where i can find one?

 

[BEan]

where to install the sensor?n what do i need (eg.sensor,adaptor n etc)?

 

[gilos]

sensor is already got with the gauge...

the only thing u need to get separately is the adaptor in between the upper radiator hoses to screw in the sensor...which is what i'm trying to find now heheh... :rolleyes:

like this one..see

fren... fitting the adapter with ur radiator hose is a good idea.. provided the size fits... and it shouldn't block the flow of coolant travelling to your engine... i would strongly suggest u try to get a NPT thread (-t- ) fitting to your original water temp sensor together with your aftermarket gauge sensor... thats the best place to monitor water temp.
btw, i have the adapter for sale.. the one connecting via the radiator hose... around RM60. better looking than the picture u provided. cheers.

there's two NPT thread given(1/8" and 3/8")...but both also cannot fit ngam2 to the original water temp sensor...sigh...

that's why i am looking for the adapter...may i know ur contact no. & location...thanks :)
