Yes thank you, Google was indeed the first place I looked.
I obviously wasn't cear in my original post, a turbo timer isn't quite what I'm looking for.
I don't need to keep the engine running, I just need to have a 12v supply to my electric pump and electric fan for a few minutes after switch...
I have a pump and fan that run when the ignition is on.
I need them to continue for a few minutes (to avoid heat soak) when I switch off.
Basically I need to delay the relay switching off when the power is removed.
I thought it should be quite simple but I'm stumped - any ideas?
