I've been given a sailboat which is in a significant level of disrepair. Hooray, projects!
The problem I'm currently facing is that there's no water pressure, even when I turn on the switch that gives power to the water pump.
I took a multimeter to the wires that feed into my water pump, and I seem to be getting 12 volts there. That then leaves the problem somewhere past those wires. I'm pretty clueless on how to run it down, though.
Shurflo has a parts list (PDF) so if you know what's busted you can order individual pieces.
How can I diagnose this? I have lots of time but little in the way of financial resources. I also have little background knowledge but I'm keen to learn.
Book recommendations are more than welcome if you know any. I don't really know what this kind of repair is called, tho.
