The PowerPulse is designed to take a small amount of power from the battery and “Pulse” it back into the battery. It takes roughly 2 seconds to “load” the circuit to provide the Pulse input. The complete pulse cycle (load > pulse > re-load > Pulse again) takes about 5 seconds. So, a connection of good solid integrity (bolted on) would need to be made for at least 5 seconds for the red LED Pulse indicator to begin to flash indicating that battery conditioning has begun. On an extremely discharged battery or battery pack flashing can be slower.
