I have a compressor that is giving me a problem. I think I know what It is, but not sure. When I turn it on, it pumps fine, but as soon as the PSI starts to build up, its as if I am letting less volts to the unit, and gets slower, like if it needs more electricity. The other day I was on the trail, and had to air up, and It started to slow down like half or 1/4 its strength. So I turned my radio off, lights and anything else i had, and the compressor ran faster, but not up to full speed. Its never done this. Its 8 months old. The 7 months that I had it, I ran it with out a tank nor a check valve. And I blew a 150PSI hose cause the pressure built up in the lines. I also found out I had the Oiler backwards. So the cylinder got no oil. So the only thing I can think of, is the cylinder head is shot or seal is broke, thus fighting its own pressure. Anyone have an idea. I now have it connected to a tank, and it only goes up to about 80 PSI and dies. If I let some pressure out, it comes back.

well from my view it seems that if ur turning all the other stuff off, ur not gettin enough input, possibly your alterator's going bad, if the compressor is going bad then i dont see how it would matter, that is if theres is a fuse which i dunno, if not then yeah it prob is trying to draw more amperage from ur battery

which unit do you have? what is the amp draw?
I agree with the other poster; our alternator is going out.

Its the DC5000 from AIM Industries. I believe it only has a 18 amp draw. But depends on PSI. I never had a problem with it before. I might try, re, wriring the whole thing to see if that does the trick. I just fell like it might be something wrong with the unit itself. But not sure.

Hmm, you're first guess may be correct. as it heats up now it starts to freeze up drawing more power to keep going until it can't get enough to pump the same volume of air. I would stop using it until you find out what the problem is before you do blow your alternator.

I have been told it could be my alternater going bad. But Kirk has the same setup, and can pump his tank up no problems with the truck off. So it could be my Optima Battery. I have ran it dead 4 times since I got it a year ago, and had to jump my neibors truck about 15 times. I have been told that I need to trickle charge the battery for a couple of days since its a dry cell battery to repair it to its normal state. Everytime I ran my battery completly dead, I jumped my truck to go to work and have never charged it.

I had a 110v air compressor do the same thing..It was a poor ground problem..May be worth a look..

Sounds like your battery or the wire (and connections) bewteen the battery and compressor.

You might what to get your Battery Load-tested.

 

[Blacksheep]

I think you are right, its the Ground. IM going to bust out the Dremmel and sand down the frame, put a new connector, and re ground the wires. Also going to trickle charge the battery.

 

[1bille1]

Well that's your problem. GEt a good automatice RVcharger and it doesn't have to be trickle. ALso optimas aren't "dry cell" batteries- they just don't leak when punctured due to a sponge ( AGM- absorbed glass mat)holds the electrolyte. Maybe you still can save your alternator before it dies of overexertion.

 

[Blacksheep]

If I were to get a new alternator with better higher amp, which one do you recommend. Cause I plan on adding more electronics to the truck.

 

[Blacksheep]

Got it working. It was the ground. Used new Bolts and sanded down the frame raw, and kaboom. And now that I have spent 6 hours wiring my ARB, IT WORKS. WOOHOOO

weee! ain't the simple and cheap fixes the best?

Hell Yea. Now I can;t wait to use the locker on the trail this weekend.
