Icon8 Compressor issues!!!

K so I don't know what's been happening with my compressor...

But it seems maybe my wiring isn't good enough? Maybe I need to move my ground because I'm using well over the gauge wiring for the compressor to make sure I don't over draw through a small wire.

My compressor has been going out, before it was a lil smoke here, then one pushed out water, then one would pump up to about 80 psi, but it wouldnt push anything into the actual tank lol... I don't know what's happening, but tonight was a different story.

With everything how it normally is when I flip the switch on the dash, turns the compressor on. Then I did it tonight, nothing happened at all. Checked all the fuses and tested the wire going to the compressor, making sure it had power. Everything was working. Took the compressor apart and everything was still connected, I'll go get a new one tomorrow, but I'm getting tired of replacing my compressors once a week.... I know I know, it's not a Viar, but I only paid $50 plus $6 for a 3yr warranty, and when it works, it doest the job no problem! I just don't know what's causing me to go through pumps like this...

Should I just move my ground? Try a new ground wire? It's on the same bolt as the ground wire for my courtesy lights under my doors (come on when the door opens)... I need some ideas guys! Thanks.

How long is your ground wire? You want it as short as possible.

Where is it mounted?

Are you running the power for the compressor through a switch or are you using a relay?

I'm running the ground wire about 7ft or so I want to say... It comes up through my bed But I actually think I can use the aluminum in on the toolbox as a ground, I think I used that as a point when I was using the test light...

Also it goes as follows for the power..

Battery to fuse to switch, from switch to compressor with switch on compressor always on. I'm no good with wiring relays, I never can remember the numbers and where they go lol...

what kind of compressor is it? I was having problems with losing ground, and I just had to move it, that and make sure that your ground is on bare metal, not paint. And are you useing a pressure switch, if you are it sould be bad.

It's a cheap $75 dollar compressor from Harbor Freight. I've got 3 buddys runnin em and never had a problem... So I think it could be my wiring... I'm gonna shorten the ground to like 3ft at most... See if that stops it.. But I don't have a Pressure switch yet, I'm gonna be getting one soon for 120psi since the tank is only rated at 125psi.

Trevor...remember, i eliminated the switch on the compressor. Shorten that ground, and see what it does. After that, get a good compressor.....after i eat through 3 of the el cheapo harbor freighters, i'm getting a nice Viair.

and use a relay.. you can even use the relay to control the gorund OR use a ground signal to turn on the relay, either one significantly lowers the amperage draw on the switch..
