HELP - Wiring a electrical 220 V motor.

I'm trying to configure this motor on the dock. I followed what I think is the correct setup based on the diagram. But really need a second opinion, can't afford to replace the motor if it goes poof!

Please look take a look at it.

The dock power has Orange, Black, White Red and Green

The Motor has Blue, Yellow, Red, orange, black, white

I read the diagram to say.

Connect Dock.Red and Dock.White to Motor.Red

Connect Dock.Black and Dock.Orange to Motor.Blue

Connect Motor.Orange, Motor.Black and Motor.White

Connect Dock.Ground to Green ground screw on motor.

It looks like you wired it for CW rotation. CCW rotation takes a different wiring configuration. Is this the right motor?

It appears to be a single phase motor so how could it be reversible unless the motor leads are reversed by a outside controller ? Is there a reversing drum switch being used ? The motor nameplate schematic is showing a two conductor power in, yet I see 4 "dock" wires with a white neutral on a 220 service . Huh ?

I was assuming the "Dock White" was a power wire and not a neutral since he is using the 208-230 volt diagram and he titled the thread ".............220 V motor". I also assumed the power wiring is coming from a controller of some sort because he also seems to have 4 power wires and 1 ground.

The dock power has Orange, Black, White Red and Green
Assuming this is a replacement motor, what happened to the original motor and how was it wired?

Motor Switch

it's got an up/down switch mounted near it. I was assuming it just changed the way the current was sent.

The original motor had 8 white wires labeled 1-8. So there wasn't an easy way to just 'match' them up. There was no information on the original motor, it was 25+ years old.

I found a wiring diagram for a similar up/down switch. I couldn't find the original. It seems to have all the right colors, only I had a difficult time following the diagram. Maybe one of you guys can translate it.

not sure if this helps.

More info

ok... So after pulling the carcase of the old motor out of the garbage. It appears to be a Baldor VL3507. I replaced with a Us Motors, Tefc, 3/4 Hp, 1-Phase, 1725 Rpm Motor, T34c2jcr.

I was able to pull off a better wiring diagram from their website.

Based on it, I think the wiring should be:

Dock ------------------|------------ Motor @ High Voltage
_______________________________________
Black (L1) -----------|------------Blue (L1)
White (L2)-----------|-------------Yellow & Black (L2)
Red---------------------|-------------Red
Orange----------------|-------------
Ground (Green)-----|-------------Ground Nut
--------------------------|--------------Orange, Red & White

So it looks like my problem may be that I have the Orange wire (not sure what it does) going to my L1 on the motor.

Fixed it.

Figured out that I'm not an electrician... So, the fix was to hire one. Came out and repaired for $60. I'm ok with that. Lift works flawlessly now.
