Hello,

I am a new sea ray (and boat in general) owner and was hoping someone could help me. My bilge blowers will not turn off unless I kill the starboard on port engines controls on the DC Main panel.

I have even tried killing the blowers 1 and 2 switches on the breaker panel and they still stay on. The helm switch panel does absolutely nothing.

Thank you for your help
 
Does your 99' have the switch pads and EIM's or do you have discrete switches?

Welcome to CSR!

Edit:
Never mind, I looked it up... You have discrete switches. I would suspect a failed switch first.

He has separate switches.

The bilge blowers have a Sea Ray proprietary electronic controller that allows one switch to control multiple blower motors. The relay in that controller is stuck in the closed position. It is a sealed assembly with no serviceable parts and is only available from a Sea Ray dealer. The controller itself should be located under the dash panel fairly close to the actual blower switch and show have "blower control" stenciled on the outside of the case. You might try tapping the control module but if that doesn't work you will probably have to order one from Sea Ray t hru a dealer.
 
since this is a 'new to you' boat it may be possible that the previous owner rewired the blowers to stay on any time the engines are running.....i have heard of this being done before....

Sounds good. When I first used the boat, the blowers were not on. Once I hit the blower switch however they turned on and stayd on so I think that FWWEBSTER reply makes the most sense.

I will take a look at the wiring as well CliffA. This boat definetly had a "tinkerer" using it before me.
 
Discrete fused systems
Discrete switches for everything
EIM and CanBuss are pure junk
