    I have a non auto pump and want to use it with a float and also wire it so that the float can be bypassed by push button controller, hence manual operation any help please

    You install two wires at the two terminals on the float switch to a switch so that when the switch is toggled the wires will act like the float switch has closed and make the pump operate.

    No power to fuel pump

    First step, a simple step, check the fuse for the fuel pump and replace if needed. Step two, disconnect pigtail from fuel pump, turn ignition on to the pre-start position so that the instrument cluster is illuminated. Step three, determine with a volt meter if sufficient voltage is coming from the wires by connecting negative and positive to their respective polarities on the pigtail connector. If voltage is sufficient, then replace the fuel pump. If no voltage is present, trace the electrical line to its power source to make sure the wires are not cut or missing insulation. Repair as needed. If this does not help, take to your mechanic. Hopefully, this will FixYa problem!

    How to connect the 3 phase power supply to a 3 phase synchronous motor with control panel

    I assume you have 3 phase power where this is going? The panel has 3 legs, 2 are 110 volt and one is 208 volt, you will need a tester to find out which is which if it is not marked, the motor should have a map on it for the wires to attach to, they go the same way, two, 110 and one, 208, I hope this helps, There will be one wire for a ground or a solid wire separate from the unit.

    1 Answer

    Some submersible pumps have a gray motor box to start the pump & some submersible pumps have the new style motor box built in and is not lighting proof. some 240vac are two wire and three! I would like...

    The difference in the two pumps is that with a three wire pump the start and run capacitors are in the gray box. With a two wire pump the caps. are built into the motor. Because of this with a two wire pump you only need to run the 240v down the well to the pump. The yellow wire on the three wire pumps is the igh voltage wire that come from the start cap. I have used both pums but usually use the two wire because they are easier to hookup and the wire is cheaper because you only need to run three wires. (2 hots and ground) On large HP pumps you will always have three wire motors because the caps. get too big to get them in the motor. It is best to go three phase with big pump if you can.

    Wiring a 230V 3 phase heat pump

    yes, this is quite important when it comes time to turn the motor. in 3 phase, motor rotation direction is critical importance. however, it is a simple matter of trial and error if only a fan is involved...not sure of consequences if freon pump is turned backwards...may want to remove pump wiring try "bumping" the fan only...your method for this "fan only" is yours to figure out. try to set to "fan only" somehow then apply power. if fan turns backwards, the take any 2 black wires and reverse connections. fan should now turn in proper direction.
