Warning horn system brain fart E40TELEDS

E40TELEDS

Side mount controls with the buzzer inside the remote control.

Warning intermittently horn stays on solid. Does this regardless of wether engine is running or not.

Everything has been checked, actual temps, wireing harness, key switch, checked for faulty sensor (I think, see below), etc... Tan wire has been checked for short to ground on both the vessel side of harness and engine side. I even swapped out the harness with a known good one.

I am having a bit of a brain fart here. I can't remember what component works the buzzer for the self check. The buzzer has brown and purple wires going to it. I am fairly sure that I have either a bad buzzer or a fault in the self check system that leaves the buzzer on.

Is it the purple wire that is supposed to activate the buzzer momentarily when key is first switched on? If so, what component controls this? Seems to me that the Purple wire is the power for the buzzer and the Tan completes the circuit to ground? Is there a check for the buzzer? Even though I am getting a solid tone would it be possible for the oil tank or the VRO to send a solid tone if they had a fault? Disconnecting each component individually has no effect, is that a valid check to rule them out? Maybe I should dig out a manual...

Replace the buzzer.

Thanks Racer...Thats the direction I have been leaning...will order one this AM.

this might help if its not the buzzer, from another parts site​, interesting about 3 and 4 wire plugs.
5007421 - Johnson Evinrude VRO Fuel Oil Pump

4 Wire Replacement VRO Pump for Johnson / Evinrude

Used on 2 cylinder 40-50 HP and 3 cylinder 60 TTL Replaces the following previous VRO pump part numbers: 0438404, 0435554, 0174875, 0174725, 0174568, 0174262, 5004562.

The 5007421 comes now with a 4 wire plug instead of a 3 wire plug that your original VRO pump had. This kit includes the attachment to make it a 4 wire plug. The extra wire provided is a purple wire. It is to be attached to your terminal block. The reason is to be a more reliable way to get the 12 volts to the warning horn. In the past with the 3 wire the warning horn was ran off your charging system, Which in cases has sent faulty alarm sounds or not sent one when needed. Now with the purple wire you get 12 volts as soon as you turn the key on.

1985 and 1986 motors that were never updated to a rubber mounted pump will need conversion kit number 0175225 .

Check for the original part number for your motor from the parts listing for your engine model number.

Had the same thing happen Turned out the buzzer itself was shorted. Replaced and fixed.

Well is seems obvious the actual buzzer works and does it's job. Now the circuitry feeding that buzzer may have issues. But the buzzer itself works, otherwise you wouldn't be hearing it. I don't know how it is connected, or if there are other circuits associated with the buzzer as a complete replacement item. If so, they replacing the entire buzzer module is your only fix. But it the buzzer is only a buzzer, then you have other things feeding it as the problem. JMHO

Thanks guys, I just put an extra set of controls I had on it. Problem solved. Now I just have to remember that this set of controls needs a buzzer.

These buzzers have a wee circuit in them.---This is what sounds the buzzer momentarily when the key is turned on.---And as it now obvious that this circuit fails and the BUZER needs to be replaced.
