RE: Engine Warning Buzzer

Tim: The transmission(zf630) sender is on the top, next to the neutral safety sensor. The overheat sender is a switch, closes at some oil temp showing an overheat. It was set up from the factory to sound the buzzer, same buzzer as the low engine oil pressure and high water temp.
If the Tach is coming of the alternator there would be an extra wire. Try disconnecting it to see the tach go to 0. Agreed if the tach does come off the alt a broken belt would make it go to zero. You gotta notice it though before you start cooking things.

FlyWright: feel free to contact me here, your Balmar install souldn't be to bad, single engine? I will try to post a picture of what I did here on a new thread. I'm sure you know you will need a larger cable coming off the alternator.
