Posted January 20, 20241 yr Has anyone opened up the turbo actuator to see what failed? Some have core charges so maybe there is an easy fix.
October 29, 2024Oct 29 Funny you post this. I am having a hell of a time with the actuator on my DPS turbonator! I found replacements from China, ordered two. One has already died. Now it goes into limp mode every time I hit about 35psi because the actuator draws too many amps. Long story short, I'm diving head first into making my own controller with a hella actuator...
October 30, 2024Oct 30 Author The man I was helping had to turn in the old actuator and the core was voided if I opened it to see what was wrong and what was rebuilt on the new one. I suspect there is a potieometer inside for position sensing that wears out. I see John Deere uses a lot of oil pressure powered actuators on VGTs maybe better choice.
