T&T: A/C pump electrical hookup

[Michael Liddle]

Hey Listees

I'm having more problems with my a/c pump and installation of wiring.
Anybody out there with input I would appreciate it. Another night of no a/c
in 80 degree and 80% will not be fun.

Let me preface by saying I'm no electrical genius. The motor/pump I bought
was very expensive and I don't want to hook up wrong and take a chance of
shorting it out.

There are three wires that were hooked up to the old pump: green, black and
white. The pump provides water for three a/c units. It has its own circuit
breaker on the panel, so it must be ON, and is wired in series with the a/c
units so an a/c unit must be on before the pump will run.

Unfortunately the pump I bought is not an exact duplicate of the one that
came out, of course. The motor/pump is dual voltage. There is a plate on the
motor that is separated by "low voltage" and "high voltage", which I believe
is between 115 and 220. My boat is 115. I am planning to move the internal
wires with bayonet connectors as indicated on the plate to conform with the
"low voltage" setting arrangement. So far I think I'm comfortable with that.
OK?

Now the green wire coming from the circuit breaker panel on the boat is
ground and I have a place to hook that up. Now the pump did not come with
any instructions or wiring diagrams, other than the plate on the motor.
Additionally on that plate it is marked with numbers that correspond to
numbers at the connectors 1 thru 6. 1 and 2 are marked as "line" on the
plate, with "BLK" indicated for number 2. However, I believe that is meant
to indicate the internal wiring BLK wire and not the one coming from the CB
panel. I know this is probably basic, but where do the BLK and WHITE
connectors from the CB attach to the motor? I wanted to make sure I had this
right before connecting.

Please, some input.  I would like to get some a/c and a good night's sleep.

Thanks for the input for this electricaly challenged listee. It is
appreciated.
