Re: 1988 Evinrude VRO Wiring
LA..... When you refer to the "tank", I assume you're speaking of the oil tank. The black wire would lead to a powerhead ground, the other wire (tan) would join in with the other tan wires (VRO and Heat Sensor) which lead to the warning horn.<br /><br />The warning horn should sound off when you ground any of those tan wires (have the ignition key in the ON position). If it doesn't, find out why as that will be your only warning of big trouble (No Oil to the engine or Overheating).<br /><br />With the engine being underwater, the VRO pump should absolutely have been replaced. Was it?<br /><br />You say at the beginning of your post that the engine was/is a 1988 model. However, at the end of your post, you refer to it as a 1998 model. Which is it?<br /><br />Hopefully you've been able to verify if the engine has been rebuilt or not as saltwater, even if someone was able to get the engine running within a short time, may cause damage that will only show up later.<br /><br />The VRO pumps that first came out with a warning system had three wires leading from the back of it to its rubber connector plug. This warning system would create a false warning. Later, the VRO incorporated a four (4) wire warning system that corrected that condition..... and this type VRO has been superceded many times.<br /><br />You can check the oil side of the VRO by simply having the engine running, then clamp off the oil line close to the engine. The warning horn should engage within sixty (60) seconds or so, beeping every other second. If it does not, find out why! Let us know what you find.
