installed a bilge pump this week and it seems to work but then today it would turn on and off by itself with the switch on. I then turned it off then turned it on and it didnt run, did the same again and then ran is it to do with my wires?? Is it not always getting the signal when i turn on the switch.
check your connection on the battery, if you crimped terminals check these, sounds like a loose connection... its not on a float switch???
