I was at a repair yesterday where the fuse was blowing on #4. I took out the fuse and was checking the solenoids to figure out which was #4. Without the fuse in the timer, I was zapped! And it was more than 24 volts. WeatherMatic Lawn Master timer. I did not have my meter to check out what the xfrmr was putting out, but it was more than 24 volts that zapped me. She then informed me that when she bought it years ago, she bought it on sale for being "re-built". Hmmm.... I'm thinking timer is shot. It shold not be putting out power with the fuse OUT of the timer. And dial was turned to off. Weird things man.
