Controller Function Test

Turn ignition off. Check controller function by connecting a 12-volt test light to test terminal on controller. Position test light so it can be viewed from driver's position. Turn ignition on. Note system operation and compare test light times to TEST LIGHT TIMES  table. If test light times are within specification, system function is correct. If test light times are out of specification, disconnect power at both batteries and replace controller unit. Repeat this step.
