That's your Pressure Switch. It's actually for turning on the compressor automatically when the air in your tank goes below a certain PSI.

[frame_basher#1]

How much would it cost for a new one

[$krap_IN_flesh]

about $18

[frame_basher#1]

where locally can i get one

[$krap_IN_flesh]

that i couldn't tell you but I can say get those dam wire nuts off there

[frame_basher#1]

the wiring on this truck is fucked up those wire nuts are everywhere on my truck and zip ties to lol and would anyplace that sells compressor stuff have them like sutherlands

[$krap_IN_flesh]

they may

[ScottXGTR]

if you have a grainger or other industrial supply place nearby they would carry them. might even check with big rig suppliers as well.

[frame_basher#1]

I went to checker lastnight and they said that they can get them for semis but they have 5 wires instead of 3 but I have to compressors but only one of them is hooked up so should I go with one with more then 3 wires and same psi

[ScottXGTR]

depends on what the other 2 wires are for. they might be for a manual override switch or something else. but long story short a pressure switch is a pressure switch. you just gotta figure out the wiring portion of it.

[frame_basher#1]

ok thanks guys for the help

[frame_basher#1]

ok i cant find one that looks like this one and all i can see in the old one is 175 psi everything else is rubbed off

[ScottXGTR]

it will have 2 psi ratings. the lower one is the turn on rating, the higher one is the turn off rating.

the ratings will depend on what compressor you use and what its rated for. 110/145, 145/175, and 160/200 are the common ones ive seen.

[frame_basher#1]

so can i just use one of the small one i have seen online just as long as it has the 175 on the shut off end

[$krap_IN_flesh]

if your compressor's are rated to go that high then yes

[frame_basher#1]

i have to viar 380c's and a 12 gallon tank but only one of my compressors is hooked up

[$krap_IN_flesh]

thats alot of work for 1 380 to fill up 12 gallons

[frame_basher#1]

i have to of them but i cant figure out y the other one wont work its hooked up but wont run when i get the pressure switch im goin to try and hook up the one that hasnt ran to c if it works or not but where on line is the best place to buy the pressure switch i need suicide doors is out of them

[$krap_IN_flesh]

take a straight hot wire to it if it doesn't come on then its more than likely fried. cause thats even to much tank for 2 380's. I'd only do a 12 gallon with a EDC. I' dont use electric on more than 8 gallon.

[frame_basher#1]

will do and it might not be a 12 but it look thats big lol here is a pic of my set up the compressor on the left is the one that donw work

[frame_basher#1]

ok new update i got the switch to work but the one compressor that dont wok i think its fried cuz it has power and ground is there a way to rebuild it

[Mr.Ryan]

Not for a viar that I am aware of. Air Zenith can be some what rebuilt but as far as I know the viar comps are not rebuildable.

[frame_basher#1]

well that sux lol
