Abstract: A block heater test system for testing continuity in a vehicle's block heater. The block heater test system plugs into the power cord of a block heater to test continuity for the purpose of making sure the block heater can be powered. The block heater test system relies on a battery. So, no other power source is needed; but alternate power sources can be used. An indicator light or audible tone indicates a fault in the block heater or indicates correct operation of the heater depending on the design. The small nature of block heater test system and the weather resistant housing allow for easy use during inclement weather.
