so i just installed my boost gauge today and i love it. very snappy and looks great. only 2 things. when just starting in first when im still in vacuum, the needle is very shakey looking. is that normal? and also its a little bright. i have it hooked up to the pink wire for the positive and the black wire for the ground. should it still dim with the dimmer knob? tell me what you think??

anyone know if the dimmer still works if hooked up diff and any ideas on the shakey needle

 

If u jave the cobalt series its actuall eletrical gauge yes u have a vacuum line to the map sensor from the autometer package. But its not a true mechanical
I have a mechanical gauge myself I don't use a.d it directly goes to a vacuum source from the gauge to the line. About it being shaky. U can have a loose vacuum line, ow compression, sticky valve, bad tune ect.

Jave means have lol sorry bout the mispellings

 

I still don't understand why people swap the factory gauge....something to do?

 

i think so

 

match with the other cobalt gauges mayb =p

 

this.
i have a blue led dash kit blue dome lights and dual blue interceptors.

 

im pretty sure it is a mechanical. it has a vacuum line that goes from the gauge to the vacuum source. and then it has a 12v and ground solely to power the light

 

i think my dims a little is your always lite up or just let up when the other gauge lights are on

 

I've never seen. A cobalt series as a mechanical bit u can,see it icant. Lol our gauges in our cars are junk. There off by either. 5-1.5 lbs that I've seen and a mechanical gauge sees whays happening that secound.

 

im pretty sure its always on. when i use the dimmer knob nothing happens either
this gauge sees whats happening in real time too. it doesnt take forever to the needle to get to where its going. you floor it and it jumps right there

 

if the light is always on you have it hook up to the wrong power wire

 

i have the + hooked up to the red wire and the - to the black wire. where should they be?

 

you want to use the gray wire for power
then the light will come on with the other gauge and will dim with the dimmer

 

alright ill switch it. thanks for your help

 

i have the cobalt mechanical gauge and it is not an electric gauge at all not sure where that horse **** comes from. this is a mechanical gauge that has a back-light that uses electric to give you that sexy blue.

 

gotcha

I've seen a mechanical shake before, but it had a small leak..

 

I think its a small leak bc I didn't get teflon tape for the treads yet

 

so im still having problems with my boost gauge needle shaking. only if first gear and then its fine. i checked for leaks and everything seems fine. any ideas

 

its fine my does that also a little at part throttle i cant look at it at wot lol

 

alright good to hear that its alright... just my intercetors in today and look great above the boost gauge

 

irrc the cobalt gauges are not mechanical, they're electronic but don't have a remote sending unit. ie, the gauge needle is still moved by electricity even though there's a vac line running into the gauge. I just dont understand why people keep buying autometer gauges, they're super expensive and the still use shitty incandescent lights inside... and they're sold at autozone, instant turn off as to their quality.

 

the electricity that runs to the gauge is soley to like up the LED yes LED on the inside. it is a mecanical guage that was cheap. i paid 60 bucks for it. not expensive at all
