Why Jacobsen ECLIPSE 360 Lawn Mower key switch is ON but there is no power to MCU or RCU?
- BBrenda MontoyaAug 7, 2025
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.
