John Deere Z425 zero-turn mower won't turn over.
John Deere Z425 zero-turn mower with 23-hp Briggs & Stratton.
Turning the key produces nothing more than a click and no cranking, even with a fully charged new battery and freshly wire-brushed terminals and lead connectors. Brake is on and steering handles are stowed outward for correct microswitch positions.
Relay? Wiring? Leads?
Any insight would be much appreciated.
