hello
today i took out the pse vacuum pump and put in a new 20amp fuse , it did not blow so my pump is toast. i took the pump apart and the ground wire going to the motor was not connected. i was happy for a second thinking , i found my trouble, but that would not make the fuse blow. i put power to the motor and it was seized which heated the ground wire and the solder dripped off , thats why the wire was loose. i took the motor apart cleaned it, it ran for 3 minutes than stopped again. i ordered a new pump for $600. i cant wait to get it. is there any programming that needs to be done? and what is the other black box and theres also a plastic tank with air or hydraulik lines they also connect to something that is covered in grey foam, its rectangular about the size of a small loaf of bread. the box, tank and rectangular foam cover are located behind the vacuum pump.
thanks
