aerator and recirculate problems

I have a 1999 Sprint bass boat that has developed a few elect. problems.
About 3 months ago my aerator pump which pumps water into the live wells
quit working. I removed the pump and checked it, was bad. So I replaced
the pump, but when I tried it with the switch- nothing. I can run a hot wire
to the battery and it works fine. Now I started having the same problem with
the recirculation pump. Pump went bad but when replaced I get the same
results. The lights on the switches come on but the pump will not run. The
switches look the same but have different #s. Both say Carling but the #s
are VJD1 9842 and VJD1 9747. They have 8 terminals on the back but only
7 are used. I have a volt/ohm meter but do not have a diagram for how they
are supposed to operate. If anyone can tell me the way to test for a bad
switch or has a diagram of the switch operation, then I can tell if I have a
switch problem or a wiring problem. Also it has switches for the same operations on the bow panel, but will not work from these switches also.
Any help will be greatly appreciated.


Thanks
Les

Labor Day,
I went out this morning to check the voltages comming out of the recirculation pump switch and it was working.. Gremlins I guess.. Now to the
aerator pump switch. I hope my diagram will help. I checked the voltages
comming from the aerator pump switch and here is what I found.


With swtch in up pos. With swtch in neut. pos With swtch in dwn
12.29v- neg post 0.00v neg post 12.35 neg post
12.29v- not used 0.00v not used .200v not used00.80v- 12.30v 12.33v 00.0v 12.33v 12.37v
12.37v- 12.28v 1.50v 00.65v 00.60v 1.00v

This is looking at the switch from the back side
Maybe this will help with the trouble shooting.

Re: aerator and recirculate problems

A swtich does not have a NEGATIVE post unless the switch also has a built in indicator light. The ground terminal in that case is ONLY for the light and has nothing to do with anything else. Your numbers are also meaningless because we have no idea which terminals you are referencing. A swtich with eight terminals has a high number of connection combinations and we also don't know the arrangement of those terminals. If there are two rows of terminals arranged vertically, the switch is essentially two separate switches operated by a single lever/rocker. If there are four terminals in each row, placing the switch in the center position probably connects the center two terminals. Placing the switch up connects the bottom two terminals in each row. Placing the switch down connects the top two terminals in each row. Switches are ON-OFF devices so you either measure 12 volts or you don't. All measurements should be between a swtich terminal and battery ground (wherever you find it). If you have a companion switch at the bow, you have what is very similar to a 3-way switch in your house where the lights can be controlled from two different switches.

Re: aerator and recirculate problems

Sorry Silvertip
The way I tried to post it showed each terminals voltage but when I tried to post it, it was always rearanged. Lets try it this way. Looking at the back side of the switch there are 8 terminals. 4 on each side. Starting at the top it would be L1 then L2 and so forth. Same on the right. Now with the switch in the up position (it is a lighted switch) L1 shows 12.29v-L2 shows 12.29v-L3 shows .8v-and L4 shows 12.37v. On the right side terminal
R1 is ground for lights. R2 is not used. R3 shows 12.30v and R4 shows 12.28v.
With the switch in the off position L1 shows 0.00v- L2 not used- L3 shows
12.33v and L4 shows .65v. On the right side R1 ground- R2 not used -R3 0.00v and R4 .65v.
With the switch in the down position L1 shows 12.35v. L2 shows 0.20v. L3
shows 12.35v and L4 shows 0.60v. On the right side R1 is ground- R2 is not used- R3 shows 12.37v and R4 shows 1.0v
I hope this represents the picture of what I am trying to say better. I just
dont want to order a switch if it is just a wiring problem.

Thanks a bunch
Les
