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.
