Just purchase brand new single engine key switch and after hooking everything up and am now getting any buzzer when key on and no buzzer when kill switch is pulled. Motor starts when key turned over. Could this be a defective key switch?

can you explain that a little better?
what do you mean by any buzzer when key on?
and how are you testing the buzzer when kill switch pulled

I was under the impression that when the key switch is turned to ON that the buzzer should beep and also when the kill switch is pulled with the key turned to ON the alarm is supposed to beep continuously. My switch does neither.

some motors should beep with the kill switch disconnected and the key turned to start,but the motor should not start when you do that
never heard of a Yamaha to beep when just turned to the on position.
also no one but you knows what motor you have

Single engine Yams do not beep when the key is turned to the on position.

As 99yam says, pull the kill switch and turn the key to the start position. The horn will sound.

I have a 2008 90TLR 90HP. I tried testing the alarm with the kill switch pulled. The motor will turn over with NO ALARM. Also i installed new digital tach and oil sensor harness. When i turned key on the tach says my oil level is at lowest (No alarm here either) but reservoir is full. How to i drain this oil out and check strainer and sensor? See picture below.

After doing some research I believe that the hose circled in photo is drain hose. I should be able to test sensor and alarm by draining the tank till it sounds correct?

is there a buzzer mounted in you controller?
have you tested it with 12 VDC to see if it works?

well if it has a new buzzer in it, you need to find out if it gets 12V+ to it with key on, and if the other end of the buzzer has a good ground to make noise

I drained the tank with the key on and checked out the oil level sensor and strainer. I cleaned the strainer out and the alarm did go off once. I’m not getting any oil level on my new tachometer so I’m thinking the oil level sensor is bad. Am I missing anything or should I replace sensor?
