Hi, I have a 12V DC Hargraves brush pump with four wires and I'm hoping someone can help me figure the wiring. I have attached a picture of the pump to this post.
So there are four wires; a red, black, blue, and white. Can anyone confirm if the below configuration is correct?
Red: positive 12V DC supply Black: negative 12V DC supply Blue: PWM control input White: sense (maybe; not sure if this is correct)
I have looked for wiring schematics on Hargraves site but did not find anything.
