Our 1999 Aerbus has been providing us with great service. We recently made a short move inside the same rv park. Everything worked. Now, at the new site, the jacks won't go down. We checked all fuses wecould find, brought the oil resevoir back up to one inch below the fill hole. No leaks, jacks look good, Found two fuxes next to motors under the hood. Found a fuse described as F10 in good shape. Tried lowering with engine on and off, withgenerator on, cleaned terminals to battery. Hear clicking sound T the two little motors under the hood but no action to the jacks. What has happened.?
