Hello, I have an 02 z45/25 with the ford dual fuel power that will not rabbit.
When it starts it will run at a higher rpm and when the pedal is pressed it will idle down and stay there.
I have checked LS1-4 found loose connections and checked terminal 6 on the horsepower board all checked ok no shorts meter read 1.6 ohms.
Checked for codes showed a 12 low tps voltage removed the throttle body cleaned it up opened up and checked the wipes on the board, no wear was replaced in 2010 (by the date inside the cover).
Then yesterday I was out playing with it ran the boom up and back down and bottomed out the hydraulics and and it went into rabbit, I also tried it with the boom extension same result when it was bottomed out it went in to rabbit.
So I am thinking that the low tps voltage is not the cause of the problem.
Is there a pressure switch that could be the cause of the problem?
Thanks
