Ok, this is a long story, but I am at my ropes end here. Please, please can someone help me figure why I am having so much trouble with my 12 volt pump.
First off, about 2 years ago I ordered the pump in a box 7 gpm with accumulator set up from Pressuretek.
Hooked it up and it seemed to cycle a lot, not blowing fuses but just every 10 seconds it would cycle, figure it was a leak somewhere. Cleaned a few cedar buildings with it and flushed it out and put it away for the winter.
Had a roof job last fall, the pump hadn’t been out in over a year. Set it up and realized the accumulator had a broken bladder. Bought a new accumulator, but the pump still never seemed to work right. As soon as you would pull the trigger it would switch on. The accumulator (2 gallon size) really did nothing. I tried different pressure settings, all kinds of fiddling, but it never really worked like I thought it should. And it blew about 10 fuses over the course of the job.
Fast forward to this spring, first job of the spring. I go to use the pump to post treat a driveway and it was dead.
So I figured, ok that pump was always a problem. And truthfully maybe I had somethings wrong. Maybe my wire was too small, switch too weak, etc.
So I bought a new Northstar 7gpm on recommendation of some guys on RCIA. The thought was these don’t need the accumulator because of the pressure switch they have. So I hook it up and when you pull the trigger it just short cycles. About 10 seconds, blew the fuse. So I am going for beefed up wiring.
Now I have a battery with terminal lugs, about 3 feet of #8 wire, to a 120 volt 50amp switch, straight to the pump. Pull the trigger it runs for 2-3 seconds and blows the fuse. I just don’t get what I have wrong. I put a full charge on the battery, 200 of kukri hose, I open the ball valve with no fitting so it is not restricted, blown fuse.
Please tell me what I have wrong. I need to clean some roofs and driveways. It doesn’t seem like it should be so sensitive. What do you guys think?
I’ll put some pictures in the next post.
Thanks for the help.
