Eric,

Here is what I think:

When you say this capacitor has 4 leads, I assume that you are talking about 4 terminals on the capacitor. Some capacitors have 2 pairs of terminals. A quick-connection wire terminal can be connected to either side of the pair, and the other side can be used for a parallel capacitor connection. In the case of the pump, and if my memory serves me correct, the capacitor plugs into a receptacle, utilizing the terminals on the end of the capacitor.

An electric start motor capacitor is used to momentarily boost the current to the motor to get it started. The two terminals on the capacitor are wired between the "load" (a/k/a positive) source and the load IN on the motor. When power is applied, the capacitor "charges" with boost voltage and delivers it momentarily to the motor. When the capacitor fails, the motor fails to start, and the breaker opens. I believe that this capacitor is a start capacitor rather than a run capacitor.

That is all I know about it, and by no means am I an expert on this...much of it is a mystery that I accept. I have replaced this capacitor once in Malaysia where the country voltage is normally 250 volts, and I believe the cause of the failure.

I hope this helps you.

Bill,

Thanks for all the info.

I still do not understand why this capacitor has 4 leads, can it be replaced
with one with two leads and how is it wired?

Eric,

I bought a capacitor in Malaysia at a hardware store for about $4USD.

In the US find an electronics parts store. Bring the specs to them, if they
do not have it, they will order it. Probably about $10.

You could also find a capacitor at a water-well and pump store. A 220v pool
pump probably has about the same capacitor.

The one I bought in Malaysia was not an exact fit, but had the correct specs
and works fine. Buy 2 of them.

Or go to:
Coastal Climate Control, Inc.
PO Box 4535

They will have one for about $50. Any/all of them will work. A/C people love
to sell $5 capacitors for $50.

You can get the pump to work without a capacitor. The capacitor only helps
get the motor turning. It takes some coordination. With a screwdriver spin
the shaft of the pump at the same moment that the A/C is switched ON. It
will reach its proper RMP and you are fine until you lose power or turn it
off. If you are really, really hot, I suggest doing this until you can find
a capacitor.

I believe your description of the black tubes describes the anti-siphon
plumbing for the toilet saltwater pumps. Salt crystals do accumulate where
the small ones join the larger one. To test my thoughts, have someone fill
the toilet while you are in the engine room observing. BTW, this is the
reason that the sump pump will sometimes start a pumping cycle when the
toilet is flushed...the saltwater draining into the sump is just enough to
raise the water level which will trigger the micro switch.

Salt buildup is an indication of a leak and likely a small one. I had salt
buildup at the A/C pump hose output connection, until I changed the
"one-way" valve, hose and clamps.

The A/C pump should be part of the bonding system. On BeBe, the same y/g
bonding wire that connects to the fresh water pump is also stripped about
1.5 inches and clamped to the A/C pump on the "one-way" valve. Check the
wire to the fresh water pump and see if there is a portion about 1.5" that
is stripped. It is likely that the clamp fell off.

Hope this helps,

Do you notice a lot of salt buildup at the pump hose output connection.



I also notice the same kind of salt buildup ( green) where the return
lines
enter a larger pipe on the upper starboard side forward bulkhead in the
engine room I do not know what they are for about 3 or 4 black small metal
pipes draining into an empty black metal pipe

I still do not get why there are 4 poles.

Some capacitors have twin connection poles on each side which allows a
parallel connection.

Does anyone know the specs on the raw water AC pump capacitor on the
Calpeda pump. It has 4 connections; I do not understand why 4. Possibly
2
run and 2 start? But it is one unit.
