I have a AD II pump that shorts out and blews the fuse too. I talked to them, and they said it sounds like water got in to the actual motor, and its shorting out. 175.00 for a new motor, as I bought the truck with the pump, and warranty doesn't transfer. They said if I buy the new motor, I would get the warranty for the whole unit. What do you suggest? New pump motor, or replace the whole thing.

 

there is a new version out since august
mine went again on the road out of town
replaced the whole pump motor again

when i phoned said they had a problem

installed new pump and turned down to 25 psi

si far it is running ok

 

they had some seal issues but they said they have got that fixed now.
