Does the pulser affect other equipment connected to the battery ?
Quite possibly. While the typical unfiltered battery charger is not a problem, some other types of loads, such as inverters, might shunt away some of the pulser’s output. In such a case, place a choke in series with one of the inverter leads to keep the high frequency spikes from traveling further. This can be a simple ferrite toroid with one or two turns through it, or a few ferrite beads placed over the wire.
