    Is DC why my 12V water pump doesn’t run but the LED bulbs on the same circuit are fine? The pump is by the creek and I’m thinking it can’t pull enough amps over the length of the run. Working on that today.

      One of DCs main issues is transmission distance. Its hard to say for your case without details but its a good possibility. If you have a volt meter and know how to use it check the voltage at the start of the run and compare it to the end of the run and see how much the voltage has dropped. If your trying to push 12v over 20-30ft I would say theres a good chance of it being too little voltage over too far a length. Wire diameter is also a factor if its very small gauge wiring.

        No voltage drop, but it’s an easy 80’, maybe 100, maybe even a little more. Hard to say as it cuts through the woods.

        Picked up an old Fluke at the store, I’ll try an figure out how to read amps.
