Abstract

A control method for high power accessory loads that is established by engine speed wherein a microcontroller and associated process control algorithm controls the state of a relay which in turn prevents the accessory loads from turning on until the engine speed reaches a set threshold. An optional accessory switch may be included to provide the ability to prevent the accessory from turning on regardless of engine speed.
