Electrical & Starting System Diagnosis

Starting system problems are frequently misdiagnosed — a new battery doesn't fix a bad solenoid, and a new solenoid doesn't fix an open safety switch. We test each component in the starting circuit to identify the actual fault before recommending any replacement.

What We Test

  • Battery load test (not just resting voltage)
  • Starter solenoid under load
  • Safety switches — seat, brake, PTO/blade
  • Starter motor current draw
  • Charging system — stator output, voltage regulator
  • Parasitic drain — current with key off
  • Wiring harness condition and grounds

Troubleshooting: Mower battery good but won't crank
