Ok I am having an issue with my Johnson pump blowing my fuse. This has happened three times.
My Setup:
From the power block I come off to a 20AMP fuse. One for each pump. for a total of three fuses for the pumps. I have a switch for each pump. Then from the switches two wires for each pump back to the pumps.
The Issue:
When I turn on my center switch I blow the fuse.
Testing: NOTE All testing was done on land without water going to pumps.
Replaced fuse and blew it again. It is almost instant that the fuse is blown.
Pulled the wires at the pumps and swapped the center pump for port side pump. (Seeing if it follows the switch or the pump). Center switch will work the port pump no issues. Port switch blows fuse on center pump. (Issue followed pump)
Switched back to make sure Center switch still blows fuse when connected to center pump. (It does)
Port switch powers port pump no issues.
pulled the impeller casing off the impeller and was able to spin impeller no issue on Center pump.
Pulled impeller from pump.
Turned on Center switch to Center pump without impeller. No issue.
reinstalled impeller and turned on Center pump again. No Issue.
reinstalled cover to impeller housing and turned on Center pump. No issue.
Now to the Question. When i get her wet again am I going to blow a fuse or what? Is it too much pressure having water in the lines? The other two pumps fill end empty no issue. Same thru hall for all three pumps. Ideas?
