I'm doing a few repairs/tasks on the Coach this week and came up with two questions.
Previously my Cruise Control was not working. Pressing the Set or Resume (cruise control) button did not raise speed and in Aladdin the Cruise Control always showed OFF.
So I started troubleshooting with the SmartWheel manual. I found a loose connection on the J1 connector. With that repaired, I can now raise engine idle speed with the Set or Resume buttons.
Question 1: On the Aladdin display > Engine/Trans Status shows "Cruise Off". However since I can raise the idle now, the Cruise must be on. Is it normal for cruise to show OFF when the coach is not moving or should it show On whenever the steering wheel button is pressed On? Maybe I have more troubleshooting to do.
Question 2: With the engine off, and coach plugged into shore power (20A) i am hearing a (pretty loud) high-pitched humming coming from the Big Boy solenoid. Is this normal?
Thanks.
