Note On Intermittents

If an intermittent Code B673 is being set, manipulate related wiring while in BO02 display and listen for solenoid to cycle (or stop cycling). This will have to be done slowly as this function cycles the solenoid on and off every 3 seconds. Be aware that solenoid could be at end of 3 second interval. Ensure intermittent condition can be induced a few times during the on (or HI) output interval.
