I have two SR400na heaters. One is older and only runs on 120v the other has the plugs in the control box that let you switch out to run 240v (Red plug) or 120v (black plug).
On the old style the blower motor only has three wires going to the blower motor: White, Black, and Green. I wired a plug from an outlet and hooked up the white to white, and black to black and the blower motor came on. Test complete.
On the newer heater the blower motor has a six wire plug: White, Black, Green, Yellow, Red, and Blue. Is there a way I can test this motor seperate from being connected to the rest of the system by wiring it to a plug like I did with the old style motor? Or how do I test the blower without it being installed into a pool yet?
My goal is to use the most updated parts that are in the best condition to make one good heater and then know what parts are still good for spares incase something goes wrong down the line.
