1987 Johnson 90hp alarms

[kamfonik]

Can anyone tell me what type of alarms and what they sound like on this motor, this may help me with my next question. I have a constant alarming when the key is turned on and the motor is not running. The motor runs great, plenty of smoke, thinking the VRO is working fine. When I wiggle the ignition switch the alarm goes away.

Al....your engine should have three different alarms as follow.<br /><br />Steady tone......Overheat<br /><br />1/2 second tone every 20secs or so....Low oil reservoir.<br /><br />Unrgent 1/2 sec tone every 1/2 second....no oil or restricted oil flow to VRO pump.<br /><br />Sounds like you may have a short in the control box. Or if you have the newer tone horn instead of the older buzzer type, the tone module may be going bad.

I just had my oil sensor changed which resolve the alarm problem. After 4 hours or water skiing the 20 second alarm has come back. I spoke to a mechanic who suggested to top up the oil eventhough the tank is 3/4 full.

I too had a steady alarm which was not an overheat problem....like Buck, my problem turned out to by faulty electronics in the oil tank sensor. I just decided to disconnect the oil tank alarm since I always check the oil level before heading out anyway.

If you want to check your oil tank sensor, just follow the wire from the oil tank into the engine...you will eventually come to a black sleeve like thing over the wire...it is protecting a scissor connector. Peel/slide the sleeve until the connector is exposed. Disconnect the wire, turn on key, if alarm doesn't sound, you problem was the oil tank sensor. If it still sounds, you faulty electronics are elsewhere.

Cheers.
