Hi Folks,
I am working on diagnosing and repairing a 1979 JLG 80F Telescoping Boom Lift.
Right now there is one electronically controlled solenoid valve for the "lift" function. It is part of the Racine Proportioning valve assembly. The ground wire for the solenoid broke off and parts are unavailable for this model. However, after talking with United Rentals and looking at the schematics for 80H and 80HX models, it looks as though 80H possibly uses the same Racine valve body and possibly has the same individual solenoids.
Could anyone confirm whether or not the solenoid valves are the same on the 80H and the 80F?
Currently I am dealing with a wiring problem and a bad control module at the basket controls. After that is sorted, I'll be looking into the solenoid issue. I have not removed the solenoid yet. It will probably be a couple weeks before I can get back to it.
