Hello,
I have a 12v DV motor like this one in my car that has burnt out (stopped working) several times. I replace the motor and it works for a while then stops.
The motor is connected via a fused line to the battery.
I measured with my multimeter and found that there is 12v to the motor when the car is off and 14v when the car is running.
This is a reversible motor hooked to a DPDT switch.
I did notice that there is constant power to the motor even when the switch is not pressed but there is no ground to the motor unless the switch is pressed.
My questions are:
1. Do I need to limit the voltage to 12v?
2. Would the constant voltage burn out the motor?
Any help is appreciated.
Thanks
