This system has two compressors, so the second red wire activates a second relay which in turn powers the second compressor.

This could be due to a stuck valve if you are hearing a click or it may be the wiring if there is no valve click when the switch is activated. I hope this helps. I would start by listening closely to the valve body once you trigger that wheel to deflate.

Comps would stay running.. it's just an on and off pressure sensor.

@@x2industries would the compressors get burned up if your going over the maximun psi (200psi)

@@streetclasscc5189 they will not burn up immediately, it will be pushing the compressors max pressure / duty cycle which means if ran at that rate for too long can and will cause the compressors to generate too much heat which in turn will compromise the output and or cause premature failure.

just saw the image you posted bellow tks for that !

@@HiFiP you can use one relay if it is large enough to handle the current of two compressors. The main power line will also need to be able to handle 2 x the current.

@@x2industries yeah I saw that ! I watched a guy video and he was saying 80 amps should be good

There are two diffrent gauge wires, the pressure switch circuit is a smaller 16 - 18 gauge and the compressor wire should be 8 - 10 gauge.

Yes, a positive will run from battery to relay then to your compressor.

Hello, you can do either way. If you want to use a larger 4 or 6 gauge wire and split off then that is ok,. It is also OK to run 2 separate power wires. If you are using two compressors then two relays would be needed.

@@x2industries very confusing.the pressure switch turns the power on & off to fill the tanks,bags,diff. why you need a manual switch.?.my comp needs to be on,all the time, the pressure switch controls when on/off. i need a relay so it doesnt burn out, like the last 5,. this vid does not show or help..i have 3 tanks, 15 gallon, for tires ect. a power tank would be better, but illegal in aus..stupid..

@@harrywalker5836 here is the wiring diagram if that helps: www.x2industries.com/wp-content/uploads/woocommerce_uploads/2018/07/dual-compressor-circuit-wiring.jpg

www.x2industries.com/product/40amp-heavy-duty-relay/ If you need it quick you should be able to pickup a standard 40 amp relay from a local auto parts store. Use one relay per compressor so you don't over draw your relay circuit amperage.

Thanks for the copy, we don't use the center closed circuit 30 amp pin for air suspension. Compressor pressure switch wiring only uses the 40 amp open side hence why we trim the center wire which I believe is 87a.

Sorry you are having trouble.. I think the following document will help with installing our sensors into the VU4 manifold... www.x2industries.com/wp-content/uploads/2021/08/VALVE-SENSOR-WIRING-VU4-VALVE-DIGITAL-5Z-GAUGE.jpg

@@x2industries thank youuuuu

This is likely due to the pressure switch being wired directly to the battery instead of a keyed on connection... If you would like a dual compressor wiring diagram, you could check out the link below: www.x2industries.com/wp-content/uploads/woocommerce_uploads/2018/07/dual-compressor-circuit-wiring.jpg

Sorry about that.. This document may help a bit more.. www.x2industries.com/wp-content/uploads/woocommerce_uploads/2018/07/dual-compressor-circuit-wiring.jpg

No it is not necessary to replace all the valve plugs.. Just the ones that are having the issues.. But many times it is not the plug but the surface that the valve plug sits on.. Be sure to check for debris in the valve channels and check the plug contact surface and well as the rubber end of the plug. I hope this helps,

It depends on the compressor, we include a 30-40 amp for initial turn on spike amperage. You should be good with the same type of rating in a fuse as well.

Im running a single fire stone compressor for airbags.

@@moneymay1062 should only need 30 amps or so..

They are usually 15 to 20 amp consistent, so 30amps should cover the cold start spike.

re pin it or solder direct temporarily and replace.

The valve block has 2 black wires centered on the top of the connector, all other 8 wires are +12 volt valve triggers. 2 per corner, 1 fill, 1 dump. You can take a positive test lead to check function.

Are those the wires going into the power connector? Red, white, and yellow wire?

@@x2industries yes red on + black on - and yellow on switching+ white is Illumination.

@@gordong6792 tie the red, white, and yellow together and connect to +12. This will get you running.

@@x2industries i know. It is working. This is not the problem. My problem ist how can i do the settings for warning. I can change the color and psi to bar. But what can i do with AC.1 AC.2 and AC.3 ???

@@gordong6792 ac1, ac2, ac3 is diffrent startup routines.

My compressor stopped kicking on this morning it is connected to a switch first time I've owned a vehicle on air ride with a switch for the compressor I've always connected straight to the battery what could be the issue or how would I go about fixing it.

@@classic9147 have you tried to bypass the switch by tieing the two wires together? Does this switch connect to a pressure switch in the tank and then to a relay or is it just a switch in the circuit? To elevate any issues with the compressor, you can take a hot 12 volt lead and touch it to the power input on you compressor to see if it will power up, if not then it's most likely a worn out brush or armature in the compressor and likely need a new compressor.

Might be a bad relay or bad compressor.

I can't say for sure who did make it but I can say for sure that AccuAir did not. This is very similar to a VU4 and works in the same manner but it is an imitation manifold.

You have to drill a hole into the handle, to feed the power wire. Be sure to use common sense as you want to hide the strips as best as possible..

Okej Thank you !

More recently, some folks are adding truck air horns (and even louder train horns that sound a small-seventh chord rather compared to major chord of vehicle horns) to their individual autos as a pastime or addition to the actual culture. I suggest you a site www.pbmissions.com/ which is really amazing for the car horns. Your video is very informative. Thanks for the video
