Fooking hate these gauges

after messing around with the wiring to the oil pressure gauge it now reads alot lower than it used to.

got me really paranoid even tho the prob started right after i re-did the wiring.

problem is, the pressure is spot on at idle but never really rises as it should.

for example it used to be 79 psi at cold start idle now only 65 then at hot idle would be about 28-30 which it still is.

As you drove the car and the revs incresed it rose up to 50-60 psi under normal driving.

Now it wont rise over 40 psi no matter how high the revs are??

if by some weird coincedence its not the gauge whats the worst im looking at?

pressure relief valve in the pump jammed or something?

I still think its a Euan problem relating to you messing with the wires

Seems to much of a coincidence that this happened after you did what you did.

I think your panicking over nothing mate! Chill

im sure it is andy but you know me, car has to be 100% perfect from top to bottom.

have bought a high tec TIM oil press gauge so will get that hooked up to confirm and get the SPA sent back yet again...

Have you maybe got reversed polarity euan ?

rapidcossie

would putting the live into the neutral and vice versa cause that?

Sure can i did it with some gauges on my old s2.

rapidcossie

will need to take out all the wires and start again...

i should know to leave things well alone

Plus the fact its positive and negative not live and neutral lol.

vroooom ptssssh

Euan, their bolloxed, i'll take them off your hands

rapidcossie

im no use with wiring

Take it it's wanky electric and not capillary?

rapidcossie

yeah its electric...

fitting a capilary one the mora to confim then the SPA will be back out to get tested.

probs my dodgy wiring tho

rapidcossie

dont think any wires are trapped or broken but its hard to tell...

rapidcossie

checked today with another gauge confirms the engine is cool and its the gauge at fault

Hi lads

I have had mine in my car for yrs and no problems yet

the only problem i had was the back lighting wasn't working properly

they were sent back and was sorted

Cheers marco

rapidcossie

think its narrowed down to the sensor for oil press as i have hooked the plug for oil press onto the boost sensor at it reads fine.

another new sensor needed i think

rapidcossie

haven't changed the wiring at all. Just multiplug to back of the gauges with the ignition live, earth and sensor IIRC.

so whatever the factoy wiring is for them.

rapidcossie

yeah thats what it should be..just checking...
