mike02380 Posted October 16, 2009 Report Share Posted October 16, 2009 I recently remo0ved a fishfinder which was wired in to only allow it on when the engine was running, this seems to have started the following problem; my rev meter and tilt meter constantly have the lights on, the tilt meter doesn't even work (it never did) The wires going into the control box for these are pink, black, green and yellow, coming out of the guages is only yellow, green and black, I have got the lights out by disconnecting black. please help, i'm confused and its dark Quote Link to comment Share on other sites More sharing options...
mw Posted October 17, 2009 Report Share Posted October 17, 2009 If you google trim pump wiring diagram you can get up a wiring diagram. I have this on my boat the only way to turn them off is for me to issolate the batery after i finish otherwise the battery goes flat over time My trim pump is wired from the batery direct hope this helps mark w Quote Link to comment Share on other sites More sharing options...

Bob F Posted October 19, 2009 Report Share Posted October 19, 2009 It's a little difficult to tell what's going on based on your description. What engine do you have? What make of boat? What make of gauges do you have? What is the control box that you mention? Is this just a junction box or does it contain other electronics? Simply removing your FF should not have caused the problems you describe, unless you dislodged a connection or re-connected a wire incorrectly. Gauges typically have the following wires going to them: 12v from the ignition switch which powers the main gauge mechanism. The colour can vary from boat to boat, but typically red. Check for 12v with a meter as you turn the ignition on/off. A ground wire, usually black. Another wire with 12v for the gauge light. This is usually wired from the running lights or anchor light. Usually blue. Lastly, a wire which comes from the sensor. This is used to actually move the needle in the gauge. In the case of a trim gauge this would come from the trim sensor. Usually green. Removing the black wire will remove the ground and so all the lights will go off. My guess is that the wires you describe are doing the following: Pink - 12v for gauge lights (controlled by running light switch) Yellow - 12v from ignition switch Black - ground green - from sensor Connect a volt meter to each wire and read the voltage with the ignition on and then with the ignition off. Let us know the results and then we might have some more clues to help. cheers Bob Quote Link to comment Share on other sites More sharing options...
