Sorry Kassim503 - What is that supposed to mean??? I would maybe call the 1009 a tank but definitely NOT a locomotive! LOL
This is what I need answered if anyone actually knows:
Wiper Switches
Q: What is the difference between dynamic and non-dynamic brakes?
Your vehicle has either a dynamic or non-dynamic (coast-to-park) braking mechanism on the windshield wiper motor. If you are replacing a switch, you need to know which type. This is all you need to know. Consult your Vehicle Owner's Manual (The TM does not specify). For those who need to know how they work, read on...
Dynamic brake:
Essentially, when you turn the wipers Off, they stop when they reach their park position, but they get retarded electrically to bring the motor to a rapid stop. When you turn the wiper switch Off and the wipers reach the park position (left or right), the armature of the wiper motor is disconnected from the load and immediately connected across ground. The motor then functions as a loaded generator and develops a retarding torque that rapidly stops the motor.
Non-dynamic brake:
Essentially, when you turn the wipers off, they stop when they reach their park position. When you turn the wiper switch Off the wipers continue to run by a separate set of contacts mounted on the motor, until the wipers reach their park position. At this point the contacts open, removing power thereby stopping the wiper motor. If the motor is not in the park position for the wipers, it continues to run until it reaches the park position and the switch opens as before.
Thanks in advance anyone that actually may know.
