I have a wiper motor that will be steering the wheels on a full size go-cart. http://monsterguts.com/index.php?act=viewProd&productId=4
I see it says at full load 12V/2A. I tested the wiper motor and it has 9-10A continuous output with a load(person) on it sitting stationary. A 13A stall current.
Well, I have a 18V 15A motor controller for the wiper motor with a 15A fuse in between. The wiper motor is on the front of the go cart to turn the wheels. When a person is on the cart, and the person tries to operate the steering, the 15A fuse blows. I have measured the stall current on the low speed and it pulls approx 13A. But when we try to drive it and steer with it moving it blows the fuse. Would there be a reason it pulls more than 15A when the stall current I re-measured earlier is 13A?
We actually had it stationary and had someone sit on the cart, and measured the current output for 10-15 seconds and it was pulling 8-10A continuously. But then when we connect it to our 12V power supply and roll the cart and try to steer it blows the fuse.
When you hook up the positive power to the side that is negitive in a car, you may be shorting it to ground through the housing.
