2001 Kenworth T2000. Cruise inop. Jakes okay.
Truck is parked and in PTO mode, high idle:
1. When clutch is depressed the idle does not go down - is this normal?
I bypassed clutch switch - no change.
I compared ohms with a new switch and have same reading.
1A. What should the input voltage be, with key on?
2. When service brake is depressed idle does not go down - is this normal?
I bypassed the service brake switch - no change
3. When parking brake is released idle does not go down - is this normal?
I bypassed the parking brake switch - no change.
When I remove either of the 2 connection leads idle will drop.
Is this a good question?
