60 HP Evinrude VRO ( alarm )

[duke3]

Hello out there.<br />My alarm system on my Evinrude 60HP VRO from 1990 is not working.<br />The purple wirer from the remote control, is not connected any where in the motor. But the purple wirer from the VRO-pump hase the owner of the motor before me, placed at the primer solenoid valve together with the purple/white wirer ???? WHY ???? According to the diagram, the purple from the VRO-pump, should have been connected to the purple from the remote control.<br />I have tryid to put the wirer to the temp.switch directly to ground, when the key was in start pos. but there was no sound from the buzzer. I know there is a purple wirer (+ 12V when ignition switch is in on-pos.) to the buzzer, and a black wirer to ground. Also the TAN wirer is connected to the buzzer. But how is the buzzer electrical build ?? Is it the TAN-wirer there is giving a signal to a coil in the Buzzer ?? Or ???<br />And also, how is the VRO-pump electrical build up ( I have 4 wirers to my VRO. purple, gray, black and TAN ) ????

here's what I did with my 86 Johnson 60hp (an absolute piece of junk from day one). After two VRO failures, I just said chuck-it.<br /><br />The first time, I had no oil pressure, fortunately died at the dock. The second time was excessive oil usage, twice the normal rate and lots of smoke.<br /><br />I just emptied the oil reservoir, disconnected the wire to the oil pressure alarm so it would not bother me, and ran premixed 50:1. So the VRO just sits there pumping gas, but no oil.

Thanks h_lankford for your answer.<br />The motor is not smoking, runs okay and the VRO pump seems to work OK. So I will keep it on. But its the buzzer (horn alarm) there is giving me problems. There is three wirers to the buzzer (purple, black and TAN). If I shall use a buzzer with only two wirers, how shall I then connect it ? Is it OK for a two wirers buzzer to connect purple (+ 12V) and then use TAN wirer as ground ?

Re: 60 HP Evinrude VRO ( alarm )

You dont wana mess with that tan wire. Thats your overheat warning sensor. It blows the horn when it gets hot and grounds out.<br /><br /> You can test overheat warning by sticking a sewing needle into the tan wire and use jumper wire on needle and touch head bolt. Horn orta blow.<br /><br />Good luck!

Duke....the wires to the horn module are there for a purpose. The purple and black provide power to the horn module. The tan wire is the signal input to the module to make it sound. The tan wire goes back to the engine and is either fed a signal from the VRO pump or heat sensor. I don't know why the previous owner placed the purple wire at the primer solenoid. It should go on the terminal strip on the engine. (I don't have a diagram in front of me so I'm just going from memory) The purple wire from the pump should also go to the terminal strip. If you are not getting any tones from the horn module, it maybe that the horn module is bad and needs replaced. Recheck the wireing and make sure it's correct. Recheck the horn by grounding the heat sensor lead. If no alarm sounds, either the horn module is bad or the diode (I believe there is one in your harness) is open.

Thanks for answer.<br /><br />I have tryid ground the heat sensor lead ( when key switch was in "ON" pos.) but no sound from the buzzer, so Im sure the horn module is bad. (the diode is OK) !!!<br />Well OBJ, you are writing, that theTAN wire, is the signal INPUT to the horn modul. But how can the signal from the temp.sencor be an INPUT signal for the horn, when the diode only will pass current the other way ? . As I can see in my diagram, the TAN wirer must be a signal, there is sending to ground through the diode, temp.switch and is ending at engine ground, or am I wrong ?<br />Also how strong is the signal in the TAN wirer (volts and amps) ???<br />I know the puple at the horn is +12V, and the black is ground. But what happens electrical in the horn when there is comming a signal ? And what is it electrical, there is giving the three diff. kind off signals (heat: as constant signal, no oil: signal every sec. and low oil: a signal every 20 sec) ?<br />So......yes I would like to now, how it is electrcal build . Also if I later on, want to build in some diode-lamps, together with the horn. <br />And can I use those rpm, temp. for my motor, that I can find from TRENT ??? http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=28;t=006584 <br /><br />Best regards from DUKE3

Re: 60 HP Evinrude VRO ( alarm )

Duke3,<br /><br />I just went through this after installing a new VRO on my 89 50. The directions say to connect the purple wire on the VRO harness to the purple wire on the motor harness. The propblem is that at the big red main connector of the motor harness, there is no pruple wire on the motor side of the harness. The previous owner who connected it to the primer probably thought that the purple white wire was the one to connect. After looking at the wiring diagram for my motor, a pourple wire is located in the wire harness before the big red connector and stops at the connector. I peeled the covering of the harness and spliced my purple wire from the VRO into that pruple wire. This wire is necessary becuase it supplies power to the VRO to monitor everything and to pass power to the horn in case of a problem. Hope this helps.

Re: 60 HP Evinrude VRO ( alarm )

When I repaced my old style VRO pump with the later version, the wiring was different, but.... The instructions covered how to make the proper connections on the old style harness. It's been over a year, but it seems like it was pretty straight forward and easy to understand. (Heck, I did it)<br />You might be able to get some information from a mechanic, but remember that his knowledge is part of what he sells. It would only seem right that you offer to pay him for that information and possibly even a copy of the correct wiring diagram.<br />If someone has wired the alarm in some manner other than intended, chances are it either won't work correctly or they have already messed it up.<br />The factory way does work and probably is the best path to take.

Thanks a lot.<br />Thats correct, that on the big red connector, there is no purple wirer going out. so I have spiced the purple wirer from the VRO, to the purple wirer from the controlbox.
