Test the pump. you have to take it apart though. you run them with a dry seal. remove the impeller. how long does it run before blowing the fuse?
I just removed the the pump. I'll take the impeller off next. It moves freely now. Somes times the fuse would blow imediately and some times it would run for 10 to 20 minutes. And it didn't matter whether it was a 20 amp fuse or a 30 amp fuse.
I visually inspected the cord and the molded connector. It appears tha there was some slight over heating going on and one of the prongs feels a little loose.
More later once I find a motor shop and put on a bench test. Thanks
Ralphyboy,
I know it sounds stupid and I don't want to insult you, but are you using the right kind of fuses? Motors with a high starting amperage vs. the running amperage usually require a time delay fuse. Maybe someone sold you the wrong type.
Greg.
Would SB fuses be at your local hardware store?
