we have a problemon an ac-130h that we have been unable to solve for a while. when you have any power source on but our atm generator the aux pump will come online fine, if the aux is already running the atm will run with no problem but if you have ATM online when you turn on aux pump it drops down to 350 htz and goes off line we have changed almost all components that apply. currently we are changing our aux pump relay due to our supervision the only thing that is strange is that we are getting 30 ampres higher than our other aircraft if anyone has any tricks that would help us please let me know
