The auto function setting on the Rule bilge
switch no longer works with the rule
750 bilge pump
with built in float valve. Switch in auto worked fine till the delivery
from hell. Don't know when it quit but a breaking wave over the quarter that soaked the cabin
Now it doesn't switch pump on when water
level rises above the 750 pump when in 'auto'. Installed a new pump thinking it was a bad switch on the pump but it still doesn't work. When switched to 'auto' there is no voltage at the panel to the Brown 'auto' wire to the pump with the old switch. Tried a generic on-off-on switch but the pump still won't work even with 12v on the brown 'auto' wire to the pump. 'Manual' works fine with 12v to the brown and white pump manual wire. Local chandlery
didn't have the Rule 'auto-off-manual' switch so will have to drive 30 miles to West Marine
to get one.
What voltage should I have at the Rule auto-off-manual switch poles??? Does the rule switch have some kind of sensor on the 'auto' pole that works in conjunction with the float switch on the pump to make the 'function' work. Otherwise do you have to use a rule switch for the 'auto' function to get the Rule pump to work on 'auto'. Do I have two pumps with bad 'auto' function???
