04 F115 Buzzer

[silversides]

My buzzer sounds after extended cranking,no start.Is this because of low volts to ecu,? starts fast after charge to batt,this normal?Time for batt?

I am fairly sure some motors had an alarm for low voltage, but I could be wrong
with a complete Model # (motor ID) I am sure someone could tell you for sure.

And I am sure if the motor does not turn fast enough and has low voltage while cranking it could keep some motors from sparking properly

read here about flashing on gauge,its a TXRC,it does sound with lanyard off.Much appreciated!

Your primary issue is "extended cranking" itself.
An EFI engine should start within a second or so of cranking -
correct whatever is preventing it from starting
and then you don't have to worry about the buzzer.

owners manual only talks about flashing on gauge,its a TXRC,it does sound with lanyard off.Much appreciated!

where does this flashing come into play

[TownsendsFJR1300]

Fully charge the battery and get it LOAD TESTED... Basic's first..

As stated above, there shouldn't be ANY extended cranking..

Some tachometers will flash for an over temperature event, a low oil event or a low oil pressure event.

Thanks for the explanation, does the buzzer sound also when that happens?
so does his motor have a low voltage alarm and if it does would it flash on gauge also or just buz

Read about flashing here,i'm guessing oil, temp icons.Charged batt will load test.Curious if alarm sounding is telling me low volts.By extended crank i'm talking 5-6sec.

Do you have Yamaha gauges? This thing is difficult to follow....

[silversides]

yes,digital tach oil ,temp icons,eng hrs trim bar. Thanks again for your knowledge

So any of the indicators flashing when this happens?

It is not a low voltage alarm per se. It is just a symptom of what might happen if the voltage gets too low.

Generally low voltage can cause any one or more of a number of silly things to happen. A light or lights may flash, the horn may sound, the motor may go into RPM reduction mode, or the motor may simply quit running.

[99yam40]

OK I thought I had read some motor had a low voltage warning alarm.
does this F115 have an ignition system that could be affected by low voltage?
maybe that could cause the long crank time before firing up, with a bad battery or bad connection

pstephens ,icharged batt if it runs down i will check for flashing gauge.
