  If the key switch is ON but there's no power to the MCU or RCU on your Jacobsen Lawn Mower, here's what to investigate: * Check to see if circuit breaker 4 is tripped, as the main contactor might not be on because of this. * Review any fault codes on the LDU and take appropriate action. * There might be an overcurrent protection device in the LDU tripped. Check for open connection or shorted wire to battery for main contactor coil power.

  If the key switch is ON but there's no power to the LDU on your Jacobsen Lawn Mower, check the following: * Ensure the 48VDC Battery or 48VDC Buffer Battery is connected and not discharged. Check battery connections and voltage. * There might be no 12V power to the LDU because the overcurrent protection device in the PDU may be tripped. Check for an open connection or shorted wire to GND for LDU 48V power, then cycle power once corrected.

  If your Jacobsen Lawn Mower isn't moving, here's what you can check: * First, ensure the machine was started and the LDU Green Lightning Bolt is steadily on. If it's flashing, initiate the start sequence. * Review any fault codes on the LDU and take appropriate action. * Manually release the parking brake, then remove release screws and cycle power. * Check if the seat switch is functioning. MCU LED #24 should be on when you're on the seat and off when you're off it. Check the switch and harness connection. * Check connections for CAN communication. * Cycle power once corrected if an overcurrent protection device in the PDU tripped. This could be due to an open connection or shorted wire to GND for throttle pedal power, TCU logic power, and park brake power.
