Questions and answers
how do you fix the flashing light issue
@Troy R Wilkins Jr its killing the battery on the ambulance
The flashing LED on the Blue Sea Systems Sure Eject 7850 indicates an ejection alert or that AC power is present. If the LED is flashing unexpectedly, it may be due to one of the following:
1. Improper AC connection: Ensure the 120V AC shore power connection is properly plugged in and GFCI protected as required.
2. Vehicle ignition status: The unit automatically ejects the power cord upon ignition. If the ignition is on, flashing may indicate an active ejection process.
3. Wiring issues: Check that all wiring connections follow the wiring diagram:
- White (12–10 AWG) for AC Neutral
- Green (12–10 AWG) for AC Safety Ground (must be securely connected to the chassis)
- Black (12–10 AWG) for AC Line
- DC negative (–) and positive (+) connected properly
- 16 AWG wires for engine start and solenoid circuit with a 10A fuse
4. Ejection failure: The unit will attempt automatic re-ejections if a cord does not fully eject. Repeated flashing may signal multiple failed attempts. Inspect for obstructions in the ejection path or worn connectors.
Correct any wiring issues, check for obstructions, and ensure a secure AC connection. If the issue persists, the unit may require service.
