Sorry for the big avatar, just try to change it<br />I have a continous sounding alarm horn on my <br />OMC 90 HP 1991<br />I searched the board and found a lot of similar entries that helped my track down the problem unto<br />the followinf stage.<br /><br /> I followed the tan GROUND wire from the control box alarm horn to the red connector female side, over to the male side and up to both temp switches. <br /><br />Everything fine (No Ground) until then. <br />The 2 tem switches have no ground as well.<br /><br />This is ONLY true if I disconnect the 2 wires shown on the picture. <br /><br />
<br /><br />If connected, the horn sounds all the time as soon as the ign. key is on.<br /><br />The tan wire on the right is connected to the <br />"main" tan line from horn to temp switch. AT least to my OHM meter.<br /><br />The black one I dont know, has some 18K Ohm to Ground ?<br /><br />Thought this could have something to do with the<br />disabled VRO, but cant trace the black ones origin. Maybe I should get all that electric tape off of the harness ?????<br /><br />Thanks for your input
