bought one of these last week...the digital type...and cant get it to work!!

it works with the ignition on but as soon as you turn the key the display goes blank but still lit?

any ideas?

 

fitted mine at the weekend and it works fine

did you get it from R&B Motorsport?

 

no, i got it from ebay.

i swear thats the last bit of junk i buy off ebay

it was a trader though

he reckons the wiring is dodgy on the car

 

You must have it wired wrong if it works with the ignition off....

 

yes thats what we thought, we have gone over and over it and cant find anything.*

would a change in voltage cause it?




*disclaimer - i did not wire it

 

Silly boy, Mike charges 40 i think for an ACT gauge

Put a claim in on ebay forms, 9 times out of 10 money back

 

has it been wired into a live feed instead of an igniton feed?

think i did a similar thing when i wired in my gauges for the first time when i think about it.

 

i must put a firewall on ebay.....must not use....

i do it everytime and never learn

may buy one off mike soon as i need one...

cheers guys

 

cant see it being the gauge mate if it works when the ignitions on but not when you start it sounds like its not wired up right my brother bought one off ebay his works fine

 

sure if u wanna know what its just turn the car to the reds again ....... ....;p

 

i got one of them worked fine untill you start the engine so i even gave it its own power supply from a 12v batt and still done it send it back and get one from r&b motorsport fitted it and worked first time
all i can say is more e bay s**t

 

ah so not the only one who have had probs

its been really stumping us as we wired direct as well

 

was it from aautoelectronics?

 

evolution_r_auto

had no replys from them at all after i told them i wired direct!!

 

File a dispute for an item significantly not as described in paypal and get your money back

 

You need to put the sensor wire as far away from the HT leads as possible. It's the interference that makes it go blank.

 

you'r saying HT interference is making the unit power down.....

 

this is the thing the unit is not powering down the backlight is still on , its the digital display that goes...

the sensor is mounted very closs to the throttle body so not near the HT leads

 

How many wires has the unit got, and where does it say to connect them to and what is each wires label/function?

 

unit only has 2 wires, one earth and one positive.

wired the positive to both ignition and perm live just see what happens.

had a PDF file with all the instructions so cant really go wrong with the colour of the wires.

going to re-wire before its sent back just to double check.

 

Lol, 2 wires

I don't think you are wiring it wrong then

So, you connect it up, and you say it works until you switch the ignition on?

 

it works with the ignition on, when you run the engine the display goes.

i think it may have something to do with the voltage going to it?

 

Ok

so, with the car running, what happens if you connect it across the battery directly?

 

It dosen't power down all togheter, the display goes blank but the light is still on. This is caused by HT interference, so you need the either place the sensor wire as far away from the HT leads as possible or shield it. I have the same gauge and had the same problem, when I routed the sensor wire differently, it worked without going blank.

 

sensor _wire_

 

Well if that fixed your problem then fairplay, but the words "cheap" and "crap" spring to mind

No offence like
