Are you sure you have a solenoid? I know the 700 series does not come with a solenoid and after looking at the 600 manual it does not seem to come with one. If you don't have a remote control or foot switches you likely don't have a solenoid. They use a circuit braker and heavy duty switch to control the windless. If you have one you should be able to hear it click when you throw the switch to activate the windless.
