15.4 Hydraulics
 When diagnosing hydraulic problems you should first determine if the electrical system is
ok. Check all cable connections and ensure they are tight and free of corrosion. Measure
the electrical output at the valve to ensure there is voltage at the connection.
 Most valves will have an override pin. This is a small brass colored hole located at the end
of each coil in the center. There will be one for each valve. By pushing in the pin you can
manually activate the valve. There must be pressure at the block for the function to move.
 If your sprayer is equipped with a bypass valve it must be activated anytime a hydraulic
function is required.
