I have a Husqvarna RZ5426 that won't start. The starter spins. We had a lightening strike while a trickle charger was hooked to the battery so I assume that caused the damage. The 20 amp in line fuse is good. All safety switches appear good. Any suggestions for troubleshooting would be greatly appreciated.

Is the starter engaging the flywheel gear?

Very good chance the lightning strike fried the chips in the coils.
Remove the blower housing then remove the kill wires from the coils.
Check for spark.
No spark now= dead coils
Spark = problem with the mowers wiring

Is this 26 hp the command EFI or the non EFI, Or it is a Courage twin 26 hp, Or one of the newer 7000-7500 series engines. Model and spec would help us to narrow down the possible caused of your issues.

At one time most mower engines had a single wire located on the engine that could be disconnected to determine if the coil(s) were faulty or some other problem like safety switches.
