Stuff I do while Truckin

3 years ago I bought a Dynasys APU.Its a Gen 2 series and a pos.I only have 3706 hrs on it and am in Grove City Oh at ELW and they are the best but are having problems and have tried all kinds of stuff all day Friday to fix it and Monday they are going to try a engine harness.The unit shuts down and the code is for a oil pressure.It has 70 psi it runs for about 6 seconds and shuts down. I had spent money on this thing ever-increasing I bought it.Thing that go out should have never happened for 15 to 25 thousand hrs.Dynasys don't even care.Im on stand bye for dispatch and if they don't have a break down for me to get they will get back at it monday
