General Information The electrical system operates on 12 VDC. The proper battery size is 300 CCA. Before performing any electrical troubleshooting, always: • Verify proper battery voltage (above 12.4V), batteries reading 12.4V or less are considered discharged. • Check that all engine and chassis ground wires are securely connected and not damaged.
Starter Solenoid Replacement Starter Solenoid Removal 1. Park the machine on a level surface and disengage the PTO. Stop the engine, wait for all moving parts to stop and remove the key. Engage the parking brake. 2. Disconnect the battery by removing the negative cable first, then the positive cable from the battery.
