Air compressor not charging

[Dead pirate]

The needle moves up to eight at the edge of where the alarm would go off, but stops there. Could this be an electronic issue, a cold issue or is my compressor (?) Only making a little Air?

Could be a sensor...a pressure relief valve...of course the gauge could be bad...if you're getting air it's probably not the compressor

It should read more like an RPM guage but in the hundreds not thousands.
My alarm shuts off at 80-psi and if I hit the brake pedal before it reaches at least 100-psi I get the alarm and normal range going down the road is 120 for me.
Does your alarm go off and everything works as normal?
Does it just go to 8 and the alarm doesn't shut off?
This time of year it is very important to blow the moisture out of your tanks.
There could have been moisture in your guage lines and it blew the cheap plastic stuff apart somewhere which really means you have a leak that the compressor can't keep up with?
Could be a safety valve on the tank
Could be a diverter valve somewhere?
But probably a plastic line ran to something like the old stop arm on the front bumper and whoever just plugged it. Now it has been doing nothing but collecting moisture.
Run it for a while and have someone with good ears outside the second you shut it off to chase the air leak sound.
Even the old stop arm tubing could be a culprit?
Even a little 1/8" tube could compromise the entire air system?
Just my thought?

Thanks. That's definitly food for thought. Im going to try all those.

So it's working now. Its either a bad sensor or a line froze and thawed out.

It healed itself! It's a new year miracle.

Do you live somewhere damnably cold (like pretty much everywhere now, except here . . .)? If so, you may have problems with moisture in the air lines, compressor's unloader valve or air tanks freezing. This is why it's so important to have a good air dryer and to drain all the tanks of any water. The air dryer's heater for its purge valve also should work. Even if you don't live where it's brass monkey weather half the year, the air system must be kept in tiptop condition all the time - it's the only part of the bus whose failure could be fatal to you and others.

Yep...I'd go with the water issue

It had an air scrubber (?). I can't manually discharge the water from the air line. So our vet well could be. Its cold as a witches tit in a brass bra here.

It's not filling the air tank again. It's hovering at the 60 lb mark. That's the cut off for the alarm. It worked while i was driving earlier, but stop and go city driving got it below the cut off. Now I'm stuck in the city can't move. And this alarm is driving me crazy

Take a line loose and blow the lines...you've most likely got a water issue

Right on. Ill have to get a way to do that. Like i said I'm stuck in the city. Every other tool but a portable compessor. I managed to move around the corner and it dropped to 20 lbs and is staying. And it's idling really bad. Sounds funny

It would help if people could see what you're working on in your profile.

Running rough and the air compressor acting strange. I figured you had a piece of rust stuck in a valve, but the rough idle sounds like you've got something else going on there.

do you have an air dryer? a heated air dryer is a MUST to drive in cold climates.. most of them are bendix air dryers and have a 2 wire heater on them.. if the fuse is blown or heater element goes bad the dryer may get stuck in purge mode and release all the air as the compressor pumps up[ or sometimes water can run back down into the governor and freeze it.. but normally a frozen air dryer is the cause of failure to build pressure..

if there is no air dryer then you'll have all kinds of freezing issues.. including the possibility of brake failure.. you can buy air line anti freeze and put a little in the system to help keep it de-iced..

I had the air system completely freeze up on my red bus last year.. its hydraulic brakes but I had no air dryer.. the governor froze on.. the pop-off valve froze.. my air compressor pumped the gauge off the scale... cracked the head and blew high pressure air into my cooling system(the compressor has coolant in the head of it).. and blasted all my coolant all over the ground.... now I have a Heated air dryer.. its been below zero and my air system works perfectly now..

EDIT - it also froze and ruined my air gauge so I had no idea hopw much air was really in the tank.. the bus would shake when it idled because the compressor was pumping well above its design capacity..

It has an air dryer. Ill check that out. Hopefully they are not too much money. I think it's the cold. Maybe i can thaw it out and get the water out.

check the wiring to the air dryer if you can.. if the heater goes bad it can be replaced separately on most.. you should have a Bendix AD-4 or a Bendix AD-9 most likely.. thats what international used most times wasd Bendix systems.. on my DEV bus when I got it the wires to the heater had no power.. there was a fuse on the in-dash chassis panel labelled air dryer.. it was popped.. I replaced it.. hasnt happened since..

I heard you say you are in a city? i dont suppose you sare anywhere near my city?
