I did as directed. But, it didn't make any sense to me.
Is this true?
Nope, doesn't make any sense at all.
The only way a Jake brake is going to come on is to let off the fuel. Why would you let up off the fuel while going up a hill? The Jake brake is turned on and off by a electrical switch so there is nothing mechanical in the switch (being a Jake brake is mechanical), thus making no difference if the switch is on or off when the Jake brake is not activated.
I might be wrong? But I can't see how there would be a difference?
