I have one of those cheapie 15 gallon sprayers. It has a Shurflo on-demand pump, so it comes on when there is a pressure drop. I haul it behind my riding mower in a little trailer and spray along my driveway, the road and my yard.
It decided to blow fuses. First time it ran just a few seconds to build up initial pressure, then the fuse blew. I replaced the fuse, it ran fine for about 20-30 minutes before blowing a fuse again. 5 amp fuse, 4.3 amp pump. I probably have 30-50 hours on this setup with no previous problems.
Checked the hoses, the wand, the entire flow system and found no obstructions that would put unusual load on the pump.
The wiring appears undamaged and with my ohm meter there are no obvious shorts.
So, where do I go from here? Suppose the pump motor is bad? How can I check it out? What else can I check and how can I check those things?
Thanks.
