Automatic bilge pump logger

I considered using an engine hours counter, then it turned out the one in my bits box was actually 240v rather than 12, and I didn't bother to order a new one. But it ought to work.

It won't tell you how many times it switched on, but an analogue click from a car scappy wired in parallel to the pump will tell you how long it ran.

An analogue click?
