[C320-list] Bilge Pump

[Gary Magnuson]

Joe,
  Not sure I can offer any help, but is there water to pump?  I think 
some models have an internal sensing circuit that automatically runs the 
pump if there is water present.   I think I learned this the hard way 
and replaced a perfectly good pump.   Perhaps you can check the rule web 
site to see if there is a chance that it could be this type. Rule Pumps 
12 Volt DC Automatic Bilge Pumps 500 GPH - 2000 GPH feature computerized 
operation on the principle of impeller resistance. Float switches are 
not required. The pump will turn on every 2-1/2 minutes to sense for 
water. If water is present, the pump will sense resistance and continue 
to run until all the water is removed. Thereafter, it will check  for 
water every 2-1/2 minutes.Power use in the checking mode is minimal.

   Also, they can come apart to be sure the impeller is free and not 
obstructed by something.  If you can pull the pump off of its base and 
submerge it in a bucket, to see if it runs.   Then check for voltage at 
the pump, and go from there.   Let us know what you find...
