I have hydraulic monarch jack on my trailer,lunde electric roll over switch ,will not raise unless I switch wires down on celunoids ,or if it don't want to lower I swich wires from one cellunoid to the other ,any ideas on if it's in switch or should I get 2 new cellunoids ,

got pics but don't know how to shrink them,the cellunoids are 2 red little boxes on the right and left of reservoir with one wire plugged into each one

Unit requires proper voltage. Any attempt to operate below the minimum required voltage could cause system failure. Refer to Battery Cable Guide. (Following page)A. Signals which point to low voltages are:1. The minimum voltage between the motor stud and ground is 9.0 volts at maximumload conditions.2. The minimum voltage between the valvesolenoid power wire (“hot wire”) and ground is 9-1/2 volts at maximum load conditions.C. Causes for low voltage are:1. Battery capacity too small.2. Cable ends not electrically secure tobattery cable.3. Battery cable size too small for load andlength of run. See Battery Cable Guide below. Larger copper battery cable, #1, #0, or #00, may be required for cable lengths over 25 feet to keep performance from deteriorating.4. Ground cable size not equivalent or larger than the battery “hotside” cable.5. Bad joints where cable ends are bolted to battery, motor solenoid, start switch, ground and etc.6. Burnt contacts on motor solenoid or start switch.

Check for low voltage as follows: (A volt meter will be required).1. On vehicles equipped with an alternator thevoltage should be approximately 13.5 volts with no electrical accessories operating and the engine running - Check it.2. Operate pump unit under maximum conditions; this would be either under full load or when pump is running over relief (cylinder dead headed). Use the volt meter to probe each connection, cable end, and cable from the battery all the way back to the motor stud and note the voltage losses. Make the necessary repairs. Increase the voltage above the minimum required.

Defective switches are a common cause of electrical malfunction. What seems to be a serious system defect can often be caused simply by a faulty switch, especially where the switch controls two functions, that is: start the motor, and shift a valve. In those cases one half of the switch might be defective while the other half operates correctly and the fault appears to be with some other component.Troubleshooting can be done by any one of three methods:1. Use a “continuity light” to test switch. (SeeTest Equipment).2. Use a circuit “test light” to test switch. (SeeTest Equipment).3. Remove the wires from the switch and“touch” them together in the proper order to operate system.

I replaced the rocker switch,no change,i got 2 coils coming now as monarch pumps recommened it next ,you can releast the little pressure valves that the red coils set on and it will lower,got to get new tires and brakes checked this summer so if those aren't it ,when I take it in I'm gonna say FIX IT,(I can break your horse for ya,but mechanical I don't even change my own oil) Thanks everybody....

Weeeeeeeeeeeeeeeeell Paul I think right on,one of the swmall wires on under battery terminal on the dual batteries which are brand new was not contacting good enough, oh well i''ll have new rocker switch and 2 coils in case I need them,coils haven't got here yet but I will have them anyway

Monarch hydraulics by the way are great to work with, they hadn't sent the coils off yet and said no problem as they couldn't figure out my mechanical explanations,i just happened to have the battery box open and tried it again and started wiggling wires and VALA.......Thanks Everybody
