Where does the neutral hook up go for the pump

talk with an electrician
normally red is active , black is neutral
the white may be the neutral depending on the voltage in use so talk with the electrician

A 3 phase motor replaced by a single phase motor has to be connected to phase one and neutral. You're going to use more power that way. How long does it run before shutting off? Is the new pump getting hot? Have an electrician determine which wires are the phase hot and neutral. Hooking up 2 phases without a neutral will trip the thermal overload in the motor.

Actually the green should be ground, one place is phase and the other is neutral. If the Green / ground wire is not connected correctly you have a shock hazard in water.

tape off the white 220 volts you dont use a white make sure the green is hooked up if you look in the box the white is mounted to the box which is ground

None of the above. You hook your two line leads (the two hot 115 lines) to L1 and L2 and you hook up the ground to the green screw. Do NOT connect the neutral to the motor.

You do not...you only use three of the 4 wires if you have a neutral pulled out to the box. Both line wires go to the motor along with the ground, cap off the neutral.

Is it an automatic transmission?

Neutral Safety Switch not connected back to the linkage?

Put you foot on the brake switch
Put it to neutral ("N") and start the car
Put it back to PARK to warm up

=======

Stick shift

Is the clutch on safety sensor hook up?

=======

Alarm system relay disconnected?

=======

Oil pressure switch / wire not connected.

NO oil pressure will disable fuel pump.

there are diagrams inside the enclosure you can wire it by, 2hots/a neutral/ and a ground wire in and the same out to the pump motor

The light box in your ceiling should have two or three wires. Black and White, or Red, Black and White.

If you have two wires (one switch to control everything):
Black is power - hook this to the fan's power wire (and the fan's light wire if applicable)
White is neutral - hook this to the fan's neutral wire.

If you have three wires (two separate switches):
Red is power for the light - hook this to the fan's light wire if applicable
Black is for the fan - hook this to the fan's motor
White is neutral - hook this to the fan's neutral wire.

With any kind of switch its important to remember to NEVER WIRE A NEUTRAL/WHITE OR GROUND to the switch. The Neutral needs to have a continuous line of un-interupted flow.

If you only have three wires. it sounds like you just need to wire those into the electrical supply.

Hope this helps
