Hi all! I am having trouble getting a new bilge pump to work. I have checked connections and all are good. It is a 1100 Rule ( manual ). I need some help troubleshooting, any ideas?

Re: Bilge Pump

It should be real straightforward.<br /><br />Is it a three wire or two?<br /><br />If it's a two, there are only two things needed, power (12V pos) and a ground.<br /><br />If it's a three wire, you need the last two, plus a "switched" wire.<br /><br />Whatchagot?

Re: Bilge Pump

Check the motor windings with an ohm meter if you do not get continuity thru the motor, rotate the impeller manually , the brushes may not be making contact with the commutator, if it acts as if the contact is intermittent, return it to store for replacement.

Re: Bilge Pump

and after that dont work try to spray a small amount of oil on the shaft while rotating the blades.and if that dont work replace it.if it is like my boat(takes on about 1 gal. of water every 45 min) you dont want to get it to work now but not when you are far from the dock.then you will have to pull the plug and take off to have the water drain out.good luck

Re: Bilge Pump

Thanks for the responses! The 1100 is a two wire setup. I bought this unit new after the previous pump stopped working. The original pump was five years old, so I figured it was time for a new one. When the new one was installed and tested, it too had no response. I have traced from battery to ground and everything seems fine. Help!!!

Re: Bilge Pump

Can you bypass your switch to see if pump is working... could be your switch

Re: Bilge Pump

If the wires test fine then, take it back for another pump. Its possible but unlikely you got a bad 1. I have had hard drive fail after a format to install the O.S..Brand new replacement. :)

Re: Bilge Pump

Connect the pump directly to the battery terminals. If it doesn't run it is no good. That is presuming your battery is charged ;)

Re: Bilge Pump

Do you have a float switch in the bilge? If you do, make sure the float is lifted up to switch power to the pump. If you don't have a float switch, disregard.<br /><br />Did you check your fuse block?<br /><br />Did you pull your fuses and clean the terminals within the fuse block? (disconnect battery for this)This is something I do every season for preventive maintenace. 9 times out of 10 if something doesn't work right off, it is a corroded fuse block. It doesn't take much corrosion to stop the flow of 12 volts. <br /><br />If your fuse block is now cleaned and the fuses are good, make sure you have 12 volts to the switch. A test light would be handy for this test, but anything that you have that uses 12 volts will work for this test. Find the backside of your bilge switch. With your test light connected to a good ground you should get a light when you touch a terminal of your switch. Turn the bilge switch on, you now should have power to both terminals. If not, the switch is bad. <br /><br />If you have power on both terminals of the bilge switch, now test the wire that is in the bilge that goes to your pump. If you do not have power there, then there is a broken wire between your switch and bilge. If you get power and the pump still doesn't work, then hook up your ground lead to the ground wire for the pump. If it doesn't light, then the ground wire for you pump is open.

Re: Bilge Pump

It sounds like there's a decent chance it's not the pump itself. Perhaps your old one is still good. Might want to do the diagnostics suggested before you get rid of the old pump...
