It had alarm previously after engine started to remind me release the key to stop the starter motor operation. But now this alarm not working. Any idea what is wrong?
Thanks.
I had these engines and never had an alarm telling me to release the key.
I could be that you had a fault the the alarm came on when starting and now you don’t
Similar on my ad31. Alarm sounds when key turned to "On" and sounds for about 5 seconds after start up, until oil pressure comes up to spec. I think as has been suggested, you had an issue beforehand, as opposed to having one now. Did you change your oil or filter lately?
