Does PriorityStart! disconnect the battery while the engine is running?
No. PriorityStart! is designed to provide battery protection when the engine is NOT running (ignition switch in the off position). It will not disconnect the battery when the engine is running, even though the battery voltage level drops below the factory-set safe threshold. Circuits within this product recognize an “engine running” condition by sensing electrical “noise” (30 millivolts) created by fuel injectors, fuel pump, fan motors, etc., and will not disconnect the vehicle battery. If a vehicle alternator or alternator belt fails, the “engine running” circuitry recognizes the condition and prevents disconnection at the 11.9-volt threshold, allowing the vehicle to continue on the reserve capacity of the battery. In such a situation you are entirely dependent on the reserve capacity of the battery. Installed correctly PriorityStart! will not disconnect the battery while the engine is running.
