  Melissa RandolphAug 7, 2025
  If the entire electrical system of your Gehl Compact Loader isn't working, there are several things to check: * Ensure the battery disconnect switch is in the ON position. * Inspect the circuit breakers on the engine panel for any that may have tripped; if tripped, identify and resolve the issue causing the trip, as the breaker resets automatically. * Confirm that the main wiring harness connectors at the rear of the ROPS are securely plugged in. * Check the battery terminals and cables for looseness or corrosion; clean and retighten if necessary. * Test the battery to determine if it is faulty and needs replacement.
