What causes battery voltage to fall below 12VDC on MULTIQUIP LS450 Water Pump?
If the Battery voltage falls below 12VDC on the digital display of your MULTIQUIP Water Pump, preventing the engine from starting, check the fuse. Also, check the charge on the battery. Finally, check the wiring connections inside the Control Box and verify power is reaching the ignition switch.
Why Pump Engine will idle but not increase to full operating speed on MULTIQUIP LS450?
If the Pump Engine on your MULTIQUIP Water Pump will idle but not increase to full operating speed, check the Throttle Control Block Solenoid for a burned-out solenoid and computer ground activation voltage.
Why there is concrete slurry in lubrication box of MULTIQUIP LS450?
If you find concrete slurry in the lubrication box of your MULTIQUIP Water Pump, it is likely due to worn or defective urethane cups or a worn material cylinder. Replacement is necessary.
Why Material cylinder piston cups squeal on MULTIQUIP Water Pump?
If the material cylinder piston cups on your MULTIQUIP Water Pump are squealing, it is likely due to low lubrication. Check the oil level.
