Hmm.. that didn't work for me.. All I get is a doc with the name of the wave file. Can you just add the wave file to a zip and upload it or give a link to it?I enclose a recording of the sound I hear from turning off the ignition or engine until the noise stops when you hear a relay click. The duration is about 40s. This recording was done just turning the ignition on/off with a cold engine so it's nothing to do with cooling fans. The noise is a bit louder than you normally hear since I left my phone on the cylinder head cover to make the recording. I had to be creative to embed a .wav file in a .doc file then compress that in a .zip file to meet the forum file upload requirements!
I expect this noise is entirely normal but what is it?
