Release Valve Coil Test
If one or both release valves on lift cylinders are not opening up, low voltage
may be the cause. A minimum of 9V is necessary to properly energize each of
the release valve coils.
If the minimum voltage is present at both coils, the coil may not be generating
the magnetism needed to open the release valve.
How to check coils for resistance
Multimeter set OHM function.
Place test leads on coil nodes.
Reading shows 5.5 to7.0 Ω→ Coil is good
Reading shows 0 Ω → Coil is shorted out
Reading shows Overload → Coil is destroyed by burn or physical damage
