Hi, Nick. Sent you a PM (or a couple).
The lights are probably not run off the battery circuit, but fed off an internal to the engine alternator, ac voltage. So, the battery has no effect on them.
No solenoid click could be several things: bad ground connection from battery negative terminal to mower chassis, bad battery connections on battery posts (either pos or neg), or bad positive connection and ground at the solenoid.
You said you replaced the fuse.
If the seat, clutch, or attachment interlock switches aren't making up properly, you won't apply power to the solenoid.
Check all connections for cleanliness and tightness.
Once you get a click, the starter should work. If it doesn't, either the starter is no good, bad starter connections, of the switch within the solenoid isn't working properly.
Let's get that 'click' back, to start.
