DRIVE DEVICE FOR ENGINE ACCESSARY LOAD

摘要

PROBLEM TO BE SOLVED: To enable to normally drive a load even when a key switch is switched to a start position during a timer operation is being performed in a drive device for an engine accessory load energizing the load only during a period when a load drive timer is performing timer operation at a time of engine start. SOLUTION: The load drive timer 4 starts timer operation when a fixed delay time passes after the key switch 3 is switched to the start position form an on position and keeps performing timer operation for a period of a fixed time. The load drive switch 5 is turned on and electricity is carried to the load 1 from a battery 2 while the load drive timer 4 is performing timer operation, and operation of the load is completed while the load drive timer 4 is performing timer operation. The delay time until the load drive timer starts timer operation after the key switch is switched to the start position is set a little bit longer than the time required for recovery of battery voltage which drops due to start of electricity carriage to a starter 6.
