If the circuit breaker pops during a cycle in your Wipaire Aircrafts, it may be due to bad or corroded wire connections. Try cleaning the terminal and protecting it with grease. Alternatively, the motor brushes may be bad, requiring a motor overhaul, or the circuit breaker itself might be faulty and need replacement.
What to do if the Wipaire Aircrafts power pack cycles on and off after the gear is in position?
If the power pack in your Wipaire Aircrafts cycles on and off after the gear is in position, it could be due to either an internal or external hydraulic leak. To check for an external leak, visually inspect lines, cylinders, and hoses, replacing them as needed. If no external leaks are found, verify that the leak is not external by checking the fluid level in the reservoir and looking at couplings for oil leaks. If isolating the entire system still indicates an internal leak, the power pack check valve (located in the pressure port of the pump) is bad and needs replacement or reseating.
What to do if the Wipaire Aircrafts power pack does not run after gear selection?
If the power pack in your Wipaire Aircrafts does not run after gear selection, it could be due to several reasons. First, the circuit breaker may have failed; try resetting it. If that doesn't work, the pressure switch might not be pulling in. Try shorting across the pressure switch leads to see if the motor runs; if it does, replace the pressure switch. Another possibility is that the solenoid switch isn't pulling in, so short across the solenoid pressure switch leads and see if the motor runs; if it does, replace the solenoid pressure switch. If none of these steps work, the pump motor may be faulty or not properly grounded, so verify that voltage was applied to the motor and check the motor ground.
