Does a Toro zero 5000 have an alternator that can be replaced since it is not restoring the battery power ?

The automatic brake actuator provides for the start solenoid return path to battery negative, i.e. the green wire. The brake actuator must be in a "BRAKE ON" state or engine cranking is disallowed.

If you measure battery voltage at the solenoid green wire then likely the brake actuator is not in a "BRAKE ON" state.

With engine off and key in on/run position you should hear the brake actuator move from brake on/off/on with control arms out/in/out movements.

Are you sure battery is not worn out? you can have power in the battery but if it does not have 12 volts the starter will not work. If that's not the problem check the starter solenoid.

Give this link a try. Once you have the belt diagram, and the right belt, it has to fit.

Remove starter and check with battery and jumper leads.

Its called a charge coil and you'll have to have this checked by someone with knowledge. It maybe something as simple as a diode.

you need to check the actual alternator. The starter has nothing to do with the charging system so replacing that wouldn't solve a charging issue. Also make sure the battery is good

Check wiring for ground. Ensure battery is fully charged or replace. Replace spark plug. Clean or replace air filter. check oil level, all mowers have a low oil start cutoff. Bad gas? Flush out fuel tank by removing gas line, flush fresh gas thru. Reattach gas line, fill with fresh gas, always use Stabile in gas! Check fuel line for cracks and secure connection to carb. Battery should read 12.8 volts or higher. .

IF ALTERNATOR AND BATTERY BEEN REPLACED.REPLACE THE BATTERY CABLES AND CHECK ALTERNATOR FUSE AND CHECK ALTERNATOR POWER BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES FOR DAMAGE.

Usually when you have zero spark, it's one of 3 things. Either there's a shutoff that is trying to shut it off when it's not supposed to, the coil is bad, or the flywheel key is sheared.
