Waeco Asc 1000 Service Manual Jun 2026

The unit is a voltage-sensing relay with a timer logic board. It monitors the voltage of your secondary (leisure) battery. When that voltage drops below a preset threshold (usually 11.8V–12.2V), the ASC 1000 sends a pulse to your vehicle’s ignition starter or generator starter motor. Once the alternator brings the leisure battery back up to a safe level (≈13.8V), the unit disengages.

Regular maintenance ensures the longevity of the unit and prevents costly downtime. Key procedures outlined in the manual include:

If you have Rev B and it fails, the service manual suggests a "hard reset": removing all power for 24 hours to drain the MCU's internal charge pump.
