A. No! Spikes and transients can be generated by any sort of ‘inductive’ load. Here are a few examples of things that we have found that generate spikes and transients: Solenoids, Starter Motors, Electric Anchor Winches, Bilge Pumps, Water Pumps, small DC Relays, Electric Fuel Pumps, Watermaker Motors, Autopilot Motor Drives, Electric Clutches, Electric Valves (for Propane, Butane, etc), Battery Chargers, Alternator Field Coils, Electric Refrigeration Compressor Motors, Generators, Engine Shutdown Solenoids, Vacuum Cleaners, 12 Volt Tools, Fans, Inverters, Bait Tank Pumps, Electric Air Pumps, Bilge Blowers, Shower Drain Pumps, Electric Toilets! And more! The intensity of the problem varies depending upon the type of device.
